editor's note Having recently attended the Geothermal Energy Expo in Sacramento, California, I wanted to give a shout out to the geothermal community—which is seemingly expanding by the day. The Expo, which is the world’s largest assembly of related companies and organizations, was a testament to the significant (and upcoming) growth of the industry; 2011 is expected to be a good year. At the event, a new report was released, which affirmed the industry will add thousands of jobs as dozens of new geothermal power plants come online or enter the advanced stages of development, thanks to tax incentives, the federal stimulus, and strong state renewable standards. According to the report, “Every geothermal project that came online in 2009 took advantage of the tax reimbursement provisions of the stimulus bill, which helped maintain momentum for new projects and continues to create new jobs in America…In addition, the benefits of the stimulus to the geothermal industry have yet to be fully realized. About 95% of the projects receiving ARRA funding are either less than 50% complete or have yet to break ground.” (http://geo-energy.org) Nice to see from an industry that doesn’t always seem to get the attention it deserves—even despite the fact the electrical energy generated in the US from geothermal resources is more than twice that from solar and wind energy combined. Or, the fact, that the US leads the world in installed geothermal capacity with 3086.6 megawatts (MW) currently online in nine states. Today, approximately six million Americans use geothermal energy in their homes. About half of that num-

ber receives electricity from geothermal power plants; another half uses geothermal heat pumps to heat and cool their homes. (http://geo-energy.org | http://geothermal.marin.org) So, as 2010 slowly comes to end, what else can be expected in 2011? According to a report from Deloitte’s Global Energy & Resources (www.deloitte.com) released earlier this year, the energy sector is still likely to experience challenging conditions entering the new year—seems money will always be an issue (even for the geothermal industry, which still has to fully finance all of their projects that are in the works). Fortunately, sustainable energies are predicted to remain pivotal, and more and more industrial sectors (such as solar power) will “trickle down” from industrial use to small business and even residential use. This year alone, US solar power is estimated to have doubled (or will have, by the end of December), with nearly 1,000 MWs installed when factoring in all residential, commercial, and utility scale systems. And, it’s been reported that the US will surpass Germany as the largest market for solar power in the world by 2011; at which time the United States will have an installed capacity of 1.6 gigawatts (www.greentechmedia.com). As for wind power, though related investments have declined as of late, US wind energy production is set to receive a boost from high-wind speeds expected early next year (thanks, La Niña!), at least based on forecast analysis from 3Tier (www.3tier.com). To help with the momentum, this issue we offer our 2011 Wind Buyers Guide, stock full of the latest and greatest wind energy products and developments. Among other topics, we also look at M&A trends (page 8), patent rights (page 30), and some key ingredients for financing renewable energy projects (page 28). Enjoy the read, and all the best in the year to come!

Classical Rationales Propel Solar Industry M&A By C Thomas Paschall (left) & Henry Scott (right)

R

ecent statistics and deal trends reveal that the solar M&A market is undergoing robust activity as 2010 draws to an end. Notwithstanding that renewable energy M&A as a whole decreased in Q3, 2010 as compared to Q2 2010 (139 transactions, 36 disclosed totaling $4.04 billion in Q3 versus 205 transactions, 56 disclosed totaling $5.77 billion in Q2 2010), the pace of solar M&A actually increased, hurdling back to the sizeable deal volume seen in Q1. In Q3, 2010, solar M&A almost doubled the volume of Q2, 2010, with $585.65 million in disclosed transactions compared to Q2’s $298 million (12 transactions in Q3, eight of which were disclosed, compared to 11 transactions, two of which were disclosed in Q2, 2010). Although a small number of large-scale transactions disclosed to the markets can distort the underlying quarterly data, it remains that solar M&A is advancing on many fronts. These transactions are largely precipitated by what appear to be classical rationales for M&A including vertical and horizontal integration, geographic diversification, technology acquisition, economies of scale, and entry into new markets. With Feed-in-Tariff rates under assault in Europe and the US, and §1603 cash grant possibly extinct in the near future, understanding the rationales and trends driving the brisk pace of solar M&A is critical to determining whether such activity will continue at the same rate and predicting if the objectives of the buyers and sellers will be realized.

Solar M&A trends and motivations

1. Vertical integration. The most compelling dynamic driving large-scale solar M&A transactions is the increasingly pervasive maneuver by upstream panel and equipment makers to acquire downstream project generation assets. Solar panel makers, in particular, have emerged as the winning bidders in a number of high-profile auctions, outpacing suspected bids by various funds and independent power producers. The consensus view is these acquisitions are occurring for the strategic purpose of panel makers assuring a long-term end market for their products. Prominent examples of such transactions include: Sharp’s recently announced acquisition of Recurrent for up to $305 million (subject to closing balance sheet adjustments) expected to close by year-end; First Solar’s $297 million acquisition of NextLight, which closed in July; and, First Solar’s $400 million acquisition of OptiSolar in 2009. The apparent dominance of panel makers in auctions of solar energy generation portfolios, with fully commercialized projects and/or late-stage development pipelines, has meant other active bidders for solar project assets have focused on middle market asset selections and bilateral negotiation to achieve their acquisition objectives. In addition, the demand for late-stage project portfolios (i.e. with approved PPAs, interconnection agreements, and permits in place) has triggered surging demand for the management and project talent teams that have developed these assets as panel makers find themselves needing to acquire project development expertise at least through COD. 2. Geographic diversification. Based on the divergent policy incentives, domestically and internationally, both strategic and financial buyers of solar projects and the equipment makers are pursuing geographic diversification. Project acquirers are seeking the highest Feed-in-Tariff rates (e.g. through acquisitions of project pipelines in Ontario, Canada as happened with Sharp’s purchase of Recurrent), and the most green-friendly legislative dispositions. Equipment makers are looking to ensure access to diverse markets and seeking to obtain the lowest cost manufacturing capabilities. In Ontario, in particular, the domestic content requirement associated with the Feed-in-Tariff has forced panel makers and installation companies to outsource panel assembly and equipment procurement to companies with a local presence in Ontario.

3. Emergence of utility scale solar. Recent studies have characterized 2010 as the year that will be recognized as the official kickoff of the commercialization of utility scale solar projects. In 2010, more than 20 utility projects are expected to come online. Additional large-scale commercial PV projects are expected to achieve commercial operation in the near future, including the 45 MW Avenal project in California. Up to 80 MW of CSP-based projects are also expected to come online in 2010 with a substantial pipeline in place for the future. Utility scale solar projects have become more economical as a result of the long-term downtrend in solar panel pricing. In addition, these projects are attractive to large corporate conglomerates and power producers who can afford the hefty capital investments to develop and construct such projects. 4. Technology driven acquisitions. Competing technologies in the solar market are also shaping the M&A marketplace. While project finance investors have shown a willingness to lend to a variety of solar technologies, it’s becoming increasingly clear that different technologies are better suited for different types of project sizes, climate characteristics, and off-take arrangements. Consequently, certain large players in the industry have adopted a diversification strategy, adopting technologies as needed to match project economics and environmental characteristics. Manufacturers and investors alike continue to watch fluctuations in the prices for components, finished products, and electricity prices carefully. An abundance of seed money in the cleantech space means there are a number of young companies with promising technologies available for acquisition. Predictions for future solar M&A activity

The classical M&A rationales will continue to impact solar M&A for the foreseeable future with panel makers continuing to make aggressive acquisitions of project assets and equipment makers pursuing similar strategies to a lesser degree. Smaller developers will look to use M&A as an exit strategy, instead of owning and operating their projects, as larger companies will have greater expertise and capacity to procure project financing. Despite the carnage in the panel supply industry resulting from steep long-term drops in module pricing, there has been recent firming of panel prices linked to the demand for panels in Ontario, Canada and Europe, as well as the growing US market. It is likely there will be a continued emergence of new low-cost panel suppliers looking to have their panels added to the list of known “financeable” panel makers (particularly from China). Distressed acquisitions of panel suppliers, as well as project developers lacking the capital to complete their projects may occur. The solar equipment and servicing industries remain fragmented and ripe for additional consolidation so makers of inverters, mounting systems, combiner boxes, chemicals used in solar panels, as well as EPC contractors and O&M providers will continue to engage in M&A transactions. Federal and state legislation in the US will be monitored with keen interest as the fate of the §1603 cash grant, Feed-in-Tariff legislation, and RPS standards continue to be key factors influencing solar M&A activity. Overall, a seller-friendly market has emerged in the US for sales of advanced solar projects, and it will be intriguing to see how long the sellers’ market continues as buyers continue to have genuine reasons for acquiring solar assets. Competition for PPAs may have already led to many lower-priced PPAs not being financeable, which may lead to future distressed M&A opportunities.

Solar Project Bonds & Corporate Liquidity By Tuan Pham & Michael Holland

M

ention the solar industry to the average person, and he or she likely considers the environmental, renewable, or “green” aspects of solar power. For many in the solar industry, technological prospects, maybe even electricity prices, come to mind. But, for a lonely few, mention of the solar industry elicits cost of debt and corporate liquidity concerns. It is this concern over the cost of solar project debt, as well as concern about the valuation of solar companies, that is the focus here. To begin, the solar industry is quite capital-intensive with most of the capital being invested upfront (during construction of the solar-generating facility), and with relatively little capital invested after the project is operating. For the purposes of this discussion, perhaps the best analogy is between a solar-generating facility and a home with a mortgage. Much like a mortgage on a home, the value of a solar-generating facility derives from the monthly payments and the mortgage rate that an owner is willing to pay—the monthly payments are the amount paid for electricity under a Power Purchase Agreement (PPA) or a Feed-in-Tariff (FIT), and the mortgage rate is the cost of debt. As shown in the following equation, unrealistic assumptions about the cost of capital obfuscate the true value of a solar-generating facility.

Second, equity comprises almost all of the capital in the solar industry. Consequently, equity investors are more sophisticated than bond investors when it comes to solar. But, despite equity investors’ deeper understanding, solar stocks are some of the most volatile in the equity markets. To offset this volatility, investors must demand premium returns. Given this demand, even though the cash flows from solar projects are more stable than those of solar panel manufacturers, does it really make sense for a would-be bond investor to require only 6% returns, as most solar developers would like to believe? Something like that may work in Europe, where governments effectively guarantee project cash flows through their FITs, but not in the US, where the government does not guarantee project cash flows (the government loan guarantee takes a very long time and has yet to be applied successfully to a solar generating project). Instead, US utility scale solar project economics rely on the feasibility of PPAs, which are supposed to accurately reflect prevailing costs of capital. But, based on the number of uncompleted utility scale projects that litter the US solar market, it’s clear the solar industry lacks the understanding and discipline to provide knowledgeable investors what they want. Corporate liquidity: solar project bonds are not working capital

Solar project bonds

Most solar industry participants underestimate the cost of debt for solar projects. As a result, developers (especially those with low-priced PPAs), who need to find a source of debt that is larger and cheaper than what banks are willing to provide, have begun to discuss the possibility of “solar project bonds.” But, rather than providing a clear path to cheaper debt for the US solar industry, the discussion of solar project bonds winds deep into uncharted territory. First, the issuance of a solar project bond is an exception, rather than a rule. SunPower’s Montalto project in Italy recently received investment-grade ratings on its debt; however, this is unlikely to be repeated, at least in the US. In fact, to date, the closest the capital markets have come to institutionally placing solar project debt has been through bank syndications in Europe. Remember, because the European solar market is much more mature than the US solar market, European banks know significantly more about solar assets than any US-based bond investors. Also, bear in mind, most of the European solar market operates under FITs, as opposed to PPAs that predominate in the US solar industry. For this reason alone, the interest rate on a US solar project bond should be more expensive than the interest rates currently available from sophisticated banks. Of course, global interest rates are at historical lows, and bond investors are grasping for yield anywhere that they can find it; so, why not issue a solar project bond? Consider the following: will US-based bond investors know how to value solar project assets? Should the solar project bond be part of a technology portfolio, or an energy portfolio? Is the placement of a solar project bond repeatable, especially if it relies on a government loan guarantee (which carries its own set of complications)? If not repeatable, but still issued, will there be a liquid trading market for these one-off solar project bonds? What will be the ongoing credit quality of the power purchaser?

Because solar project debt is issued on a non-recourse basis, the only collateral comes from the assets of the project. (The project entity remains completely separate from any project vendors, except for the warranties on equipment and services.) Therefore, even if a solar project bond could be issued, the issuance of the bond would not mean a vendor has the working capital (cash) necessary to buy the materials to sell into the project. For instance, a vendor who intends to sell 10 MW of turnkey systems at a cost of $4/watt must have at least $40 million of cash in the bank to recognize the sale of those systems. This additional corporate liquidity (cash) comes at a price. Reconciliation of solar project bonds & corporate liquidity

As expected with any nascent industry, there are more questions than well-reasoned answers. These unanswered questions result in higher project interest rates than what most developers are willing to acknowledge. Additionally, vendors into solar projects must meet their own set of significant capital requirements. Ultimately, all of these factors create numerous disconnects with respect to financing solar projects—the divergence between project finance and corporate finance is but one (albeit important) disconnect that exists. As a result, these disparate funding silos must be reconciled if the solar industry is to meet its growth expectations, at least in the US. Recognizing the capital intensity of the solar industry is most akin to that of the energy, industrial, and homebuilding sectors is a good place to start.

Banking on Solar? What you should know before betting on a warranty By Tony Foster

ABC Medical Corporate Headquarters in Phoenix, Arizona with Upsolar Modules

C

onsumers rarely make significant purchases without considering the benefits of investing in a long-term warranty. Whether it’s a new home appliance, a piece of office equipment, or an automobile, there is something to be said for the peace of mind that comes with knowing there is a low- or no-cost safety net in place to cover unforeseen issues stemming from manufacturing defects and/or excessive product degradation over time. With large-scale systems setting organizations back hundreds of thousands of dollars or more, solar PV technologies are no exception to the warranty rule. As utility and distributed generation projects continue to gain traction around the world, installation owners are increasingly turning an eye to the importance of implementing long-term insurance coverage.

U n X ˜ U X X T

On the surface, all warranties might look the same but as more and more players enter the solar arena, the bankability of the warranties offered should be placed under the microscope. Indeed, as one begins to peel back the layers of promises and examine the real value underneath, it is apparent that some policies provide owners with nothing more than a stack of paperwork. So, what's most important to ask when investigating solar warranties? Here are a few key questions that can help evaluate and authenticate a decision. • Am I starting with the right product? A warranty should be imposed with confidence that it will rarely, if ever, be required. With this in mind, customers should always begin the process of module selection by concentrating on products from trusted technology providers. Consider the amount of time spent selecting a new television or a computer—items that are regularly replaced. Conversely, solar PV systems are expected to produce for decades, all the while sustaining abuse from the outside elements. It is truly imperative to entrust one’s solar needs to a provider committed to technological quality and longterm product stability. • Does the product have appropriate support? A barrage of solar module producers entered the PV industry in recent years, and logic dictates not all will survive. We’ve already seen the financial downturn sink a plethora of manufacturers, and more are likely to fall in the coming years. Enacting a warranty on a solar system essentially equates to having faith the technology provider will still be in existence decades down the road. • What happens to the value of a module warranty when the organization behind it no longer exists? For the vast majority, the plan is nullified, leaving system owners unsupported in the event of damage or malfunctions. It is no wonder financial lenders have grown increasingly cynical when presented with large-scale projects, hesitant to lend credence to a solar provider’s ability to deliver on a long-term warranty. A few suppliers have backstopped their warranties with insurance to protect customers from this risk. • If a warranty is insured, when does the coverage begin? Policyholders might assume system coverage takes effect the moment their signature is inked at the bottom of the contract. The reality is many plans require a waiting period, with some as long as five years, before the insurance actually kicks in. Though it’s true that the majority of issues with solar PV installations result from years of system wear and tear, a host of unexpected complications can arise within the first few years of use. Before committing to a plan, customers should take the time to read the fine print. If a gap in insurance protection is undesirable, plans are available to provide system owners with full coverage from day one.

In the rapidly changing world of solar, there are no guarantees. Fortunately, a handful of solar module providers are now providing additional backing from reputable financial establishments to provide customers with increased security. This means that even if unforeseen circumstances drive the solar provider out of business, system owners will receive coverage. The best of these policies will provide uninterrupted coverage for the duration of the warranty term. In a world full of uncertainties, the added bankability afforded through PV system warranties—particularly when backed by sound financial partners—allows consumers and lenders alike to take comfort in knowing they’ve made the safest bet possible with their hefty solar investments. Tony Foster serves as sales director, North America for Upsolar, an international supplier of solar PV modules.

Solar Energy and the Impacts on Water Supply By Eric L Garner

A

lthough increasing the use of solar energy can limit the nation’s greenhouse gas emissions, facilities that harness the sun’s energy in the California desert impact another natural resource that is difficult to come by in the arid landscape. Solar facilities can consume significant amounts of water, potentially impacting aquifers that are already over-pumped. In desert areas, the potential impact to groundwater basins from renewable energy projects has prompted California and federal agencies to develop new policies and regulations designed to protect native water resources and limit pumping activities. This has made securing a water source for these projects and getting them approved more difficult. Because large-scale solar plants are, by necessity, located in sunny, dry areas, they almost always rely on groundwater. In some cases, the question of whether those groundwater basins are hydrologically connected to the Colorado River raises another complex issue for solar projects. The legal issues associated with water in California are complex and rich in history. Understanding the hydrology, geography, and the legal framework of those issues is essential for developers seeking project approval.

Limited water supplies

Solar technologies vary in terms of their reliance on water. Photovoltaic and dry-cooled thermal projects, for instance, use relatively modest amounts of water. Wet-cooled solar thermal projects use considerably more. Developers of all projects will quickly find that water in the California desert is extremely limited because low rainfall makes recharge of underground aquifers occur at a slow rate. In some cases, groundwater rights to aquifers, such as the Mojave Basin in the Mojave Desert, have already been allocated by the courts through adjudications, leaving very limited water for new users. Most of the groundwater basins in California are un-adjudicated and are governed by the common law principle of the doctrine of overlying rights. A key principle of California water law is that landowners whose property sits atop a groundwater basin are entitled to pump water for “reasonable and beneficial use” on their overlying land. Despite this basic tenet of California water law, several solar project proponents have experienced significant resistance from state agencies to pumping groundwater for power plant cooling purposes on their property.

Staff of these agencies are making a tremendous push to require the use of treated wastewater, frequently referred to as reclaimed or recycled water, for power plant cooling. Accessing that source can be difficult, though, because recycled water infrastructure is limited and the desert regions are dotted with thinly populated cities to generate significant amounts of wastewater. One of the largest solar projects being proposed—Stirling Energy’s $2.2 billion Solar Two project—is seeking to use recycled water. A recent analysis by the US Bureau of Land Management found that Solar Two would require 10.4 million gallons of water each year to wash solar panels, provide dust control, and support other plant operations. According to the draft environmental impact statement released earlier this year by the US Bureau of Land Management and the California Energy Commission, Solar Two’s water needs cannot be met by the region's existing surface or groundwater because the aquifer is over-drafted and no new well permits are being granted. Tucked in California’s southeast corner in the Colorado Desert, Stirling’s concentrated solar project is expected to have a 30,000 solar dish system across more than 6,100 acres of federal land, according to the draft environmental impact statement. The plant, once completed, would send electricity to homes and businesses in the San Diego metropolitan area about 100 miles to the west. At full capacity, Solar Two could generate enough electricity to power more than a quarter-million homes. Stirling has proposed to use recycled water from the nearby town of Seeley to meet its demand. If all goes as planned, Stirling would fund the upgrading of the town’s wastewater treatment plant so the water meets state requirements for reuse. The company would connect the treatment plant with the solar plant via a nearly 12-mile underground water pipeline, according to the draft environmental impact statement. The river’s influence

Another issue in California is concerns related to Colorado River resources. The US Bureau of Reclamation has proposed defining hydrologically connected groundwaters to the river, which snakes along the southeastern border of California, by an “accounting surface” regulation that would limit river water use in absence of a federal Colorado River water entitlement. The proposed accounting surface in some areas extends more than 50 miles from the river, impacting proposed solar projects with seemingly no apparent connection to the Colorado River. The proposal is currently being revised, but is based on the concept that since California’s entitlement from the Colorado River is limited and groundwater wells connected to the river are considered to be diverting water from the river itself, any additional diversions must be within the California entitlement. Currently, there are three proposed projects that would fall within the 50-mile border, each one using from 300 acre-feet a year up to 1,600 acre-feet. One acre-foot equals 326,000 gallons of water, or enough for roughly two typical households per year. Although one of those projects would use a “wet cooling” technology that requires more water, the others would use the more water-efficient but more expensive “dry cooling” technology. In July of this year, the California Energy Commission weighed in on the issue of water and solar projects in the desert, articulating its stance on protecting native water resources. The commission applauded the proponents of one of those proposed projects for cooperating with the commission and electing to use air-cooled condensers instead of the originally proposed wet-cooling system. Although the decision to use dry cooling drastically reduced water demand for the project, it did not eliminate water-related impacts altogether. Indeed, the commission imposed a set of conditions on the project to offset any potential impacts on the groundwater basin that are hydrologically connected to the Colorado River. Rules for securing entitlements for the water to cool and clean solar plants are still evolving. Carefully evaluating the proposed water source, the quantity of the available supply, and the related water right is critical before initiating the permitting process.

Choosing the Right Battery for Renewable Energy Applications By Ronald Paredes & Dean Middleton

R

enewable energy applications present several unique challenges to batteries. Charging sources are often intermittent in their nature and batteries typically provide a means of energy storage that provide a constant supply of power to electrical loads, regardless of weather conditions or time of day. Loading conditions can change from day to day and the battery may be subjected to deep discharges at low- to high-discharge currents for extended periods of time. This means that batteries for renewable energy systems, such as solar or wind power, must be able to withstand discharge currents in excess of 200 ampere and currents that are as low as a few tenths of an ampere.

Battery specification: efficiency & durability are key

Lead acid batteries are the most common choice for energy storage in power systems that utilize renewable energy charging sources. Considered a mature and proven technology, lead acid battery technology is well understood and found in a wide range of applications, both off-grid and grid-tie. There are as many lead acid battery types, designs, and sizes as there are applications. Choosing the correct battery for a particular application is crucial to the efficiency and durability of an energy storage solution for renewable energy and backup power. Lead acid batteries are divided into two primary groups: shallow cycle and deep cycle. Shallow cycle batteries, also referred to as automotive or starting, lighting & ignition (SLI) batteries, are designed to provide brief bursts of high current over a very short period of time. Automotive batteries are not appropriate for renewable energy applications and will fail prematurely because they are not designed to withstand the regular deep discharge and recharge cycles typical of renewable energy systems. Only deep cycle batteries, designed and optimized for regular deep discharge and recharge cycles, should be considered for renewable energy applications given their superior performance capabilities under the challenging conditions typically associated with renewable energy systems. Deep cycle batteries: superior performance saves operating costs

Automotive batteries are often selected for renewable energy systems due to their initial low price, but are not actually cost effective over the long-term as they need to be replaced more often than deep cycle batteries. The graph, “Deep Cycle versus Automotive,” compares the cycle life of an automotive battery to a deep cycle battery.

As can be seen, automotive batteries have a significantly lower cycle life than deep cycle batteries. Although automotive batteries do present an initial cost advantage, this advantage quickly diminishes due to the battery’s low cycle life. To determine the true cost effectiveness of a battery in any application, one needs to look at its cost per charge-discharge cycle. When used in a deep cycle application, it is not uncommon for automotive batteries to have up to five times the cost per cycle compared to a true deep cycle battery. In addition to the cost per cycle, there are other expenses incurred by a battery replacement that cannot be quantified by the cost of the batteries alone. These include labor and logistical costs, as well as potential downtime of the system due to premature battery failure. “My experience of years of off-grid living and design consultation is that reliable, cost-effective power storage is essential for off-grid, renewable energy power systems. Without the proper battery other system components will not perform to capacity and be problem prone,” says Bob Skinner energy systems design and sales at Hire Electric Inc.’s solar division in Oregon. “True deep cycle, lead acid batteries are the best for these types of applications because they offer a long cycle life and the lowest lifetime cost of any energy storage technology currently available. They are, by that criteria, far superior to the often easily available and sometimes lower initial cost of automotive starting batteries.” IEC Testing: the international standard for battery performance tests

In their battery selection process, operators and installers for renewable energy systems should take into account the true cost per cycle of the battery. Independent performance testing according to international standards help buyers obtain relevant information about a battery’s cycling capability. The International Electrotechnical Commission (IEC) 61427 standard tests the battery’s ability to perform in renewable energy applications where the battery frequently operates at partial states of charge and at extreme temperatures. Some battery manufacturers have their products tested to the IEC 61427 standard by an objective and independent laboratory. This universal standard prepared by the IEC determines the requirements of the secondary batteries used in photovoltaic systems, and the typical methods of test used for the verification of battery performances. Selecting deep cycle batteries tested to the IEC 61427 standard will ensure the best overall performance at lowest lifecycle cost in a renewable energy application. Making the right decision

There are many types of lead acid, deep cycle batteries offered on the global market, and lead acid, deep cycle storage products vary in design and size. By evaluating the battery performance characteristics considering the factors outlined above, buyers will gain valuable insights needed to make the right decision and find a battery perfectly suited to their specific renewable energy application. After all, choosing the right battery for a renewable energy or backup power system will help lower a system’s total cost of ownership by increasing system stability and efficiency, as well as minimizing downtime due to premature battery failure or replacement.

Structural Adhesives A bonding alternative for alternative energy equipment By Ian Quarmby

A

lternative energy applications are a key focus in today’s marketplace, creating new jobs and reducing the world’s dependence on fossil fuels. Solar and wind energy are garnering interest from consumers looking for cheaper, environmentally friendly power sources. To make these methods even more attractive to the end-user, energy equipment manufacturers are seeking to lower production costs while increasing product reliability. One area of potential gain is in the choice of fastening systems. Although mechanical fasteners are commonly used for securing PV and wind turbine panels, structural adhesives are becoming a popular alternative. Structural adhesive benefits

Structural adhesive bonding is an established joining method that has been used in the automotive market for 25 years without corrosion issues. Structural adhesives offer the following benefits: reduced stress points, leaks, and corrosion; resistance to extreme environmental conditions; and, enhanced sealing. Metal-bonding adhesives are used in applications such as aluminum-skinned satellite dishes, commercial signage, and land-based military transport vehicles where thermally induced stresses and wind loads create fatigue conditions. Structural acrylic adhesives offer high shear strength (from 1,000 psi to 4,000 psi) over a wide temperature range (-40°C to 170°C), making them as strong as welding and most other conventional fastening methods. Unlike screws, bolts or rivets, which concentrate the stress at the point of attachment, adhesives spread the stress over the entire bond area. Adhesives act as a sealant by keeping out moisture, and they compensate for dimensional irregularities by filling in gaps on poorly fitting parts. Furthermore, structural adhesives offer a process-friendly solution. Minimum surface preparation is required. There is no need to pre-drill holes or fill in over screw heads, and re-work caused by burning from welding operations is eliminated. PV panel applications

Solar panel construction offers many opportunities for structural adhesives. Adhesives can be applied between the glass and the metallic or composite frame, and are also used to attach the frame to the rack. In many systems, the bolts connecting the array to the racking and tracking systems require continual maintenance to ensure the operating integrity of the system. Reducing maintenance checks by using structural adhesives reduces costs, allowing a portion of the savings to be passed along to the consumer, which in turn makes solar panel systems a much more attractive energy option. Mechanical fasteners can also loosen over time due to wind-induced and/or structural vibration. Structural adhesives not only eliminate the prob-


Disconnect combiners

lem of loosening fasteners, but also the need for maintenance followups. Structural adhesives also eliminate the weight of mechanical fasteners and improve stress distribution. And, huge inventories of bolts, washers, and screws can be replaced with one structural adhesive kit.

SolarBOS has announced the addition of 100 and 200 amp disconnects to their popular Disconnect Combiner box product line. The complete range of solutions now includes 55, 100, 150, 200, and 245 amp disconnects, and these can be specified with up to 36 input circuits in NEMA-3, 3R, 4 and 4X enclosures. SolarBOS Disconnect Combiners incorporate an integrated 600 VDC load-break switch into the combiner box, allowing system integrators to greatly simplify the design and installation of a PV system. Customers can configure Disconnect Combiners to match any project with SolarBOS’ online “product configurator.” SolarBOS www.solarbos.com | www.solarbos.com/products.php?cat=54&prod=14

Wind turbine application

Structural adhesives are also finding acceptance in the manufacture of wind turbine equipment. In addition to offering reduced weight, structural acrylic adhesives have proven to reduce assembly time and corrosion protection. A better bonding system

As environmentally friendly energy sources become more popular, manufacturers will be looking for less expensive, more viable product construction methods. Using structural adhesives in place of mechanical fasteners will enable manufacturers to build a better product faster, more simply and with less cost. There is a big push for corporations to “go green.” Companies are adopting sustainability themes, and their shareholders, employees, and local communities are all interested in environmentally friendly practices. Structural adhesives offer the potential for cost savings, along with the reassurance of product durability and environmental stability. Ian Quarmby is an innovation scientist with LORD Corporation.

Case Study: Solar Cell Structure Impedes Efficiency Structure of all-polymer solar cells yet to be optimized By Harald Ade, Christopher R McNeill & Chris Groves

ovel soft x-ray characterization methods have revealed two shortcomings of all-polymer solar cells, and help delineate the path for reaching the substantial, intrinsic potential of these materials. The soft x-ray scattering and microscopy experiments utilized the Advanced Light Source in Berkeley, a soft x-ray synchrotron radiation facility. In combination with device characterization and Monte Carlo studies, the relatively low rate of energy conversion in model all-polymer solar cells was found to be caused by the structure of the solar cells themselves: domains of the donor and acceptor polymers utilized are too large or impure, and interfaces between them are not sharp enough. Organic solar cells are becoming increasingly popular because they are potentially cheap to manufacture and can be “painted” or printed onto a variety of surfaces, including flexible films made from the same material as most soda bottles. A large community is researching a number of promising technologies (e.g. polymer/fullerene, polymer/inorganic, all-polymer, and dye sensitized cells), and seeks a deeper understanding of the fundamental structure, operation, and limita-

or Current voltage characteristics for devices that were cold laminated (black) or annealed at 140 °C (red). Resonant soft x-ray reflectivity measured a significant increase in interfacial roughness from 0.68 nm for the cold laminated to 2.6 nm annealed device.

Accurately Monitoring the Performance of your Solar Energy System

To maximize the effectiveness of your solar energy system, you need to know how it is performing. A Kipp & Zonen pyranometer accurately measures the solar radiation available to your system in real time. Comparing this with the power generated allows you to calculate the efficiency of the system. A drop in efficiency indicates the need for cleaning, ageing or a fault, allowing you to schedule preventive maintenance and to monitor your return on investment. Make that difference and contact Kipp & Zonen for the solutions available.

tions of these devices. The new insight by the team from North Carolina State University and the UK will lead to the creation and use of new approaches in allpolymer device technology to achieve the intrinsic potential of these materials. The active, thin layer in such solar cells has to be simultaneously thick enough (~150-200 nm) to absorb most of the light and have an internal network of electron donating and electron accepting material that is small enough (~10 nm) for that captured energy—known as an exciton—to travel to the interface between the materials where charge separation and conversion electricity can occur. One of the fundamental challenges in the field is to create such networks in a controlled fashion. Conventional tools are often unable to visualize the morphology or to characterize details of the important, often buried, interface between an electron donor and acceptor material. The field frequently advances by “trial and error,” methods that are guided by heuristic principles. Characterization that achieves improved insight can provide significant development shortcuts by providing and guiding rational design and processing strategies. Using advanced charPair distance distribution function for PFB:F8BT blends annealed as indicated. The zero acterization tools at the crossing relates to the domains size and has been determined to be as follows: Advanced Light Source As spun 140 C 160 C 180 C 200 C in Berkeley, substantial ~77 nm ~71 nm ~89 nm ~110 nm ~260 nm In all cases, the domains are larger than the exciton diffusion length, which is ~10 nm, progress has been made in understanding all-poly- contributing to the relatively low power conversion efficiency of these devices. o

mer devices operation. Through a combination of x-ray microscopy, resonant soft x-ray scattering, soft x-ray reflectivity, photoluminescence quenching, device characterization, and Monte Carlo studies, the performance of all-polymer solar cells was shown to be sensitive to interfacial structure. It was also shown that present fabrication methods lack sufficient control over the morphology of the active layer. For the studies of morphology, model polymer blends of the conjugated polymers poly(9,9'-dioctylfluoreneco-bis-N,N'(4,butylphenyl)-bis-N,N'phenyl-1,4-phenylene-diamine) (PFB) and poly(9,9'-dioctylfluorene-co benzothiadiazole) (F8BT) were annealed at different temperatures. The resulting phase separation was studied using resonant soft x-ray scattering and scanning transmission x-ray microscopy. A large dispersion of the domain size was found in all cases with rather impure compositions of the domains in the as cast blends. The observed dominant domain sizes were much larger than the exciton diffusion length for all processing conditions, including annealing at intermediate temperatures that yielded a maximum in device efficiency. Intermixing within these large domains means that not all excitons are lost to recombination; however, this hierarchy of phase separation prevents the creation of “ideal” morphologies of pure domains ~ 10 nm in size by the casting and annealing approach. Therefore, even in the morphology that maximized device performance, some excitons have to travel too far and are lost while some domains are still too intermixed—which hinders charge separation. This contributes to the poor performance of the solar cell devices made from the blend of these polymers and might be indicative of all polymer devices, in general. Other all-polymer based solar cells are presently investigated to see if their low efficiencies are due to this same structural problem. The influence of interface structure on the performance of devices has been investigated using PFB/F8BT bilayer heterojunctions. Resonant soft x-ray reflectivity provided quantitative information on the roughness of the interface as a function of annealing protocol. Only the cold laminated bilayers were sharp, and even mild annealing caused the interface to roughen. The measured roughness was an important input parameter for Monte Carlo simulations, which were used to fit the device’s current-voltage characteristics. Nonequilibrium, sharp interfaces are optimal for charge separation and optimal device performance. The challenge now will be to create small interpenetrating networks with sharp interfaces reliable enough to produce high-efficiency

devices. New fabrication methods will have to be found and might include increased use of block copolymers or processing more incompatible polymers with orthogonal solvents. Research conducted by H. Yan, S. Swaraj, B. Watts, and H. Ade (NCSU); C. Wang (ALS), J. Lüning (SSRL); I. Hwang, C.R. McNeill and N.C. Greenham (University of Cambridge, UK); and C. Groves (Durham University, UK).

Solar fuses for high-amp PV systems The new Cooper Bussmann PVS-R solar fuse provides high-amp ratings with the required fast-acting response to low PV DC faults. The PVS-R fuse is the first fuse of its kind to achieve a UL 2579 listing for “Lowvoltage Fuses—Fuses for Photovoltaic Systems.” With a dual 600Vac/dc rating, the PVS-R fuse is designed to meet the higher amperage levels of today’s larger solar power systems, while withstanding extreme high- and low-ambient temperatures, routine cycling, and opening under low-level fault current conditions. Typical competitive offerings provide only traditional time-delay fuses that are not well-suited for solar power system protection. Unlike AC systems, the available short-circuit current in PV systems is limited and requires the overcurrent protective device to operate effectively on low levels of fault current. For this reason, Cooper Bussmann has conducted extensive research and development of fuses that are specifically designed and tested to address the unique needs of PV systems. Cooper Bussmann also provides time-current curves, which follow as close as possible to actual field applications. Available in ratings from 20 to 600 amps, the PVS-R fuse is well-suited for use in re-combiner boxes and DC safety switches that operate at higher current levels, but experience the same low-level fault current conditions as combiner boxes and PV strings and arrays.

Quick Mount PV now manufactured in Canada by SunRise Power! Substrate handling wands

See us at

Virtual Industries Inc., a supplier of manual vacuum handling solutions, introduces the VWWB-2A series of substrate handling wands. Virtual Industries’ ESD-safe Push Button Wand Kit is ideally suited for handling substrates such as individual PV cells during the manufacturing process. The lightweight push-button wand is designed for connection to an in-house continuous vacuum system. Operation is simple: first connect the vacuum hose to a vacuum source and to the rear of the tool, next install the press-fit handling tip that corresponds to the size of the substrate to be handled and, finally, hold the wand handle and gently lay the tip flat onto the substrate surface. The part is now firmly gripped for manual handling. To release it, simply depress the control button. Returning the wand to the stand when not in use shuts off the vacuum supply to conserve energy.

Sensors Unlimited, Inc., a part of Goodrich Corporation, has announced their high-resolution, shortwave infrared (SWIR) area and linescan cameras are being used to improve the manufacturing yield of PV cells. SWIR technology is well-suited to monitor the quality of solar thin-films, concentrated PV, and crystalline cells to maximize efficiency of the solar cell manufacturing process through final assembly of the completed modules. The InGaAs-based SWIR cameras, which operate between 0.9 to 1.7 microns, are ideal for inspecting silicon boules and wafers due to the material’s transparency beyond 1.2 microns. In machine vision applications, Goodrich shortwave infrared sensors can reveal voids in silicon boules, bricks, and ingots before they are sliced into wafers to produce mono- and multi-crystalline solar cells. They can also detect hidden cracks by mapping stress in silicon wafers and films made for solar collectors. SWIR cameras can further spot defects in the material and/or saw marks inside or on the opposite side of a silicon wafer. By applying forward bias to cells, the SWIR cameras are used to gauge cell efficiency and uniformity. This not only aids improvement of cell manufacturing processes, but also helps in matching cells with similar efficiencies to assemble into modules. The latter step prevents the loss of energy from the stronger cells, which would be lost in heating the inefficient cells. Sensors Unlimited, Inc. | www.sensorsinc.com

Higher energy output for PV systems GeckoVoltaik’s iliofix is a single-axle tracking system for flat roofs. Its uniqueness is the tracking of the rail systems. An astronomic standard setting allows for an optimum angle setting to the sunlight. The system contains two sensors at the outer edges of a module in the module field, which prevent the behind-located module rows from being thrown into shadow during the back-tracking. The elevated track of a PV system with ilioflex will generate an extra output of 20%, according to conservative estimates given by GeckoVoltaik Systems. The higher initial investments can be earned at a factor of four as a minimum. For the system, the extremely short assembly time is worth noting: the assembly time ranges at below two man hours per kWp. Furthermore, the low area weight of less than 10 kg/m2 roof area (including panels) allows the installation of the tracking system on commercial flat roofs with critical static conditions. With ilioflex even possible leakages that have been typical for roof-penetrating systems in the past are no longer a reason to cancel a profitable PV system.

Will your module last? Put it to the test. Your company may be a market leader, but are your products ready for the long haul?

lthough financing comes in all shapes and sizes for wind, solar, and other renewable energy projects, there are basic ingredients that investors use for evaluation. The following items are generally required for due diligence after an initial review of a project to see if it is within the general scope of an investor’s parameters. It is, therefore, important a developer be prepared to provide these. The items can apply to various forms of financing including PPA’s, FIT contracts, debt, equity, and acquisition. 1. Executive summary. Ideally this is one to two pages and gives a highlevel overview of the project including developer experience, site control information, PPA or off-take terms, Interconnect status, system description, EPC experience, permit and approval status, projected capital structure and needs, and proposed O&M. 2. Sponsor & EPC resumes. These should show contact information, prior project experience, website URL, financial strength, bonding capability, and other relevant data. Investors rely heavily upon a project team, and want to be confident the team can execute a project through to completion. 3. Single purpose entity description & documents. This is normally a single purpose LLC or corporation that owns the project, so required documents are the LLC Articles and Operating Agreement or Corporation Articles and By-laws. 4. Site control. For ground-mount solar or wind projects, this is normally a land contract or lease, or option for same. In the case of rooftop solar, it is normally an executed lease or lease option. The critical elements are demonstration of site control and detailed terms going forward. 5. Civil engineering. For ground-mount solar or wind projects, a copy of the site plan showing project location, set-backs, usable acreage, and any constraints would be needed. Soils reports done on land and any other civil engineering documents are helpful.

6. PPA or Off-take agreement. This is the document that provides the cash flow, which is being underwritten, so its importance is obvious. PPAs can be cumbersome in terms of legal time and expense, so be prepared for this. There are four general types of PPA’s or Off-take agreements as follows: Utility PPA: in the case of utilities, they will have their own form of PPA and, usually, do not allow modifications; however, utility PPA’s will normally be accepted by an investor’s legal counsel and are normally very bankable. Feed-in Tariff (FIT): these contracts are set in stone and not modified; however, they are generally the most bankable with investors and their legal counsel. In both cases above, the off-taker is almost always a good credit risk so credit is not usually an issue. Municipal PPAs: with municipalities, schools, etc., these will normally be fully executed and useful for presentation to the investor. These are favored by investors, as well, and the credit risk is normally minimal. Private PPAs: are generally with private or public companies, and normally need to be investment-grade credit to be considered by an investor. In many cases, the investor will require his or her own form of PPA (or a modification of the existing one) so, often times, a developer will get a PPA term sheet to be followed by the investor’s own form of PPA, which the investor’s legal counsel has prepared or approved. In the case of biomass projects, a feedstock or supply agreement tends to accompany the PPA. Financial information such as two years of audited financial statements is often required for credit evaluation. 7. Interconnect agreement. Developers often underestimate the amount of time it takes to get this agreement, yet it is a vital component. It must be fully executed by the utility or Local Distribution Company (LDC), and is normally applicable to ground-mount solar or wind projects. 8. Performance modeling. This will be based upon the solar radiation, wind power density, or other relevant energy source modeling. It is driven by component performance, as well as the above energy source modeling. It should be prepared by an EPC or a design engineer that is qualified to do such projections. 9. Proforma & cash flow. This will incorporate the above performance modeling, PPA/FIT revenue streams, any KWH escalators, project costs, incentives (federal, state, utility rebates, etc.), and any other factors that show the projected income and expenses for the duration of the PPA/FIT contract. 10. System design & construction documents. These are necessary to support the project performance projections and show all components and design for the project. 11. EPC & vendor contracts. These would show the complete project cost in a detailed line-item budget. 12. Permitting & regulatory approvals. For ground-mount solar or wind projects, full land entitlement including all environmental and regulatory approvals will be required. This can be a lengthy process, and it’s advisable to utilize a company or consultant that has prior experience to avoid costly delays. Building permits would be required as a final item prior to the start of construction. 13. System design. Project site plan, system specs, electrical design, and interconnect documents will be required. The EPC or design engineers will provide these.

14. Warranties & insurance. Major component warranties (e.g. solar modules, inverters, or wind turbines) should be provided along with all insurance coverages. These generally include Workers Comp, General Liability, All-risk property, and comprehensive insurance for the system once constructed. 15. Operations & Maintenance (O&M). An O&M plan should be in place with a company that has prior experience. There are several good companies to choose from. Every project is unique, and the above provides a general list that encompasses most project finance requirements. If the project pencils out and the above components are in place, financing should be available. Dick Talbert serves as CEO of Greenpower Capital.

By George Snyder

oday’s successful business enterprise is tech-savvy, nimble, and green. Whether satisfying consumer demand for renewable energy, or for environmentally friendly products and services, a modern enterprise stays informed about government regulations concerning the environment, values observance of voluntary environmental standards, and strives for technological compliance with both. This can be an integral part of presenting a positive image, but is not the only benefit of green awareness. When a business enterprise spends millions on renewable energy pursuits, or to develop new green products or services, the green tech they embody is a highly valuable asset. There is a real-world need for the enterprise to guard its investment against appropriation by others, through patenting that green tech. Patent rights on green tech have become highly desirable as they can improve the bottom line by warding off rival copycats, or by affording opportunities for licensing. However, the trend toward green tech patents is a two-edged sword because others are also procuring them. Therefore, before introducing its own green tech into the marketplace, a business enterprise would be well advised to search for others’ patents and determine if the green tech is “clear” of infringing anyone else’s rights. Otherwise, there could be crippling liability costs (damages, attorney’s fees, etc.). Two recent matters are illustrative. In one, a company named TDM America secured patent rights concerning a green tech solution to protect the technology from unauthorized use. Unlicensed US government contractors then commenced green tech operations to remove and process contaminated materials from navigation channels, which TDM perceived as an infringement of its patent rights. TDM sued to block the accused operations and preserve its technology’s exclusivity. In contrast, consider the plight of several companies that commercialized technology for extracting corn oil from “whole stillage,” a by-product of manufacturing ethanol from corn. Another entity, GS Clean Tech, commenced litigation against them for infringement of its patent rights. Even though making ethanol production more lucrative, thereby encouraging use of ethanol as a green tech solution, the defendant-companies were sued by an entity seeking to exploit its investment in patents. So, how do businesses go about pursuing patent rights to secure green tech advances and preserve their asset value? And, since good intentions obviously do not forestall litigation, how does one mitigate the risk of being embroiled in a lawsuit?


Patent procurement

The first step in capturing portable green tech is to institute an “audit” function that closely monitors innovations on an enterprise-wide basis. Personnel involved in research, consulting, sales engineering, and the like can be recruited to provide reports on green tech solutions that are devised in-house. The scope of their reporting should be inclusive, leaving assessment and decision on what should be pursued to an individual or committee charged with managing innovation. Those advances, which are earmarked as potentially significant, can then be subjected to searching of the patent and technological literature to determine whether the innovation is clearly un-patentable. Depending on the results, a patent application—including a detailed description of the invention and claims legally defining its outer boundaries—can be prepared. It is a good idea to work out a theory of invention-patentability, and present the theory in the application right off the bat. In doing this, rather than waiting to respond to arguments against patentability raised by the United States Patent and Trademark Office (“USPTO”), one can frame the terms of the debate in a favorable way. In general, it is helpful at the threshold to develop a rationale for the invention’s difference from preceding technology—for instance, the invention enables “clean” practice, without any substantial loss of performance in comparison to conventional technology. Of course, it is important in extolling the superiority of the green invention not to indict the applicant’s prior conventional technology in a manner that might create liability for the latter’s utilization.

fication of evidence that the patented technology is unpatentable, should dispel concerns about infringement. On the other hand, if there is no ready basis for concluding non-infringement, finding another route will be dictated (maybe one might decide to inquire about licensing someone else’s patent rights). But, in any event, forewarned is forearmed. Conclusion

Unless a business protects its green tech assets, others may misappropriate them and the benefits they confer. Patenting is a powerful way of achieving this protection. However, the innovative (or even patentable) nature of a green tech development is not insurance against being sued by someone else for patent infringement. The risk of liability cannot be insightfully determined without a freedom-to-operate study. Bearing these concepts in mind should make “greening” not only a noble, but also a profitable venture. George Snyder is a partner at Troutman Sanders’ NYC office. Troutman Sanders LLP www.troutmansanders.com

Unless a business protects its green tech assets, others may misappropriate them and the benefits they confer. Patenting is a powerful way of achieving this protection. The USPTO’s examination process typically takes anywhere from three to five years in the normal course, and there is no guarantee of success. The process can sometimes be expedited pursuant to protocols in the USPTO for handling green inventions but, again, there is no guarantee. Either way, however, staying the course can yield a patent that preserves significant competitive advantage conferred by innovative green tech. Freedom to operate

Best practices call for the vetting of a proposed green tech solution to see if it is clear of others’ patent rights before implementation. The initial step in conducting a “clearance” evaluation is structuring an effective search to uncover any patents and published patent applications of interest (these can be supplemented with patents and published applications already known to you and your colleagues). A useful technique for this is computerized keyword searching of US patent databases. Patents and applications that cannot be discarded as irrelevant must be analyzed more deeply (applications cannot be infringed unless and until they are granted as patents, but they should be evaluated to see what’s in the pipeline). Such an analysis (and any written opinion based on same) should be obtained from outside IP counsel if the goal is to obtain advice most likely to be credited as reasonable and competent by a court. The file histories of those patents and applications are obtained from the USPTO. Then IP counsel can determine whether the patent(s) and/or application(s) are sufficiently limited so that they do not cover the contemplated green tech solution or, at least, can be circumvented by an acceptable design modification. Alternatively, a search can be conducted to find literature foreshadowing the purported invention and establishing the “invention’s” unpatentability. This type of clearance work is known as a “freedom to operate” study, and is best performed as early as possible.

Reliability In Surge Protection

Why VG Technology? DC Power Systems continuously stress Metal Oxide Varistors (MOVs) without impunity. The result is a significantly shorter life (about 3-5 years) for devices that rely exclusively on MOV technology. Citel’s VG Technology is a hybrid protection circuit that incorporates our unique Gas-filled Spark Gap (GSG) with series MOV. This patented combination completely eliminates all leakage and working currents thus extending the life of the SPD by up to 5 times that of MOV technology alone. In addition, the performance characteristics that you have come to expect are not sacrificed.

Catch the Wind, Inc. CENTA CENTA manufactures flexible couplings and drive shaft solutions for torsional vibration, electrical isolation, noise, and misalignment related problems. With over 20 coupling designs, and over 16 million couplings sold, CENTA has the solution for power transmission systems driven by wind, electric motors, or gas/diesel engines. Their coupling solutions range from torsionally very soft, for high inertia systems like gearboxes and generators, to torsionally very stiff, for simple inline pump drives. CENTA’s staff of design and calculation engineers ensures equipment design receives the required attention, as well as the ideal coupling solution. www.centa.info

Catch the Wind is the developer and manufacturer of the Vindicator laser wind sensor, which can mount on the nacelle of large wind turbines to provide advanced wind speed and direction information to a turbine controller, allowing it to better align the turbine with the wind. Recent trials have demonstrated that winds vary continuously, by as much as 20°, making it difficult for conventional anemometry located in the disturbed wind flow behind the spinning rotor blades to accurately position the wind turbine for optimal performance. Analysis comparing performance of wind turbines controlled by the Vindicator system to turbines using conventional anemometry show that laser wind sensor control significantly improves the average power output while dramatically reducing the stress loading on the turbine’s major components. www.catchthewindinc.com

The 300-metric ton LR 1300 SX is one of Liebherr’s most successful crawler crane models. The new LR 1300 SX version of this crane has a main boom that permits worthwhile increases in both main boom and jib lifting capacities. In addition, the LR 1300 SX has a newly developed heavy duty jib for assembly and maintenance work on wind power installations. For this area of application, the crane is equipped with a narrow telescopic undercarriage for cost-effective travel movements when space on the ground is limited. The standard travel width of the LR 1300 SX is 8m, but the undercarriage can be closed up until its width is only 4.8m. The track width adjustment permits crane travel movements with all equipment installed. The new heavy duty jib is 8m long and rated for a maximum lifting capacity of 117t. Its full performance potential is revealed when it is used in conjunction with long booms and derrick equipment. www.liebherr.com

Holmes Murphy & Associates Holmes Murphy, through its Renewable Energy Division, provides financial institutions, equity partners, and purchasers new opportunities for grey market wind turbines. Through an insurance-backed extended warranty solution, those who have invested in a wind farm have the opportunity to sell the turbines at a fair price or refinance to revive a stalled project. The warranty takes effect after manufacturers’ initial two- or five-year warranty expires, and covers parts availability, direct and indirect labor costs, liquidated damages, and serial losses for up to 10 years after the equipment is commissioned. Businesses in the wind power industry benefit by the removal of liabilities from their balance sheets, because bond-rating agencies see the business’ financial statements differently. The result is better equity position and more prosperous balance sheets. www.holmesmurphy.com

EGS Cutaway Diagram

Making Room…Fractures are coming through! Enhanced geothermal systems By Craig Dunn

Enhanced or engineered geothermal systems (EGS), frac’ing or fracking programs, hydraulic shearing...call it what you want, but our ability to alter rock reservoirs has the power to change the geothermal energy industry. Conventional geothermal energy programs need three things to be successful: 1. Heat. Without this you don’t have a resource. 2. A transfer medium. Required to transfer the heat; this is usually water. 3. A rock environment. With enough porosity to move the heat through. In the simplest terms, if a geothermal energy developer can move enough water through hot, fractured, or porous rock, he or she can use that heat to power a turbine—and, therefore, has a potential power project. Seems simple enough, right? But, what if this incredible heat resource is trapped in solid rock? One can’t economically move heat out of a solid rock thousands of meters underground. So, should such a developer simply walk away from the potential project or work to improve the situation? The oil and gas industry had a similar problem with getting precious oil and gas resources out of tight formations. They knew these energy resources were in certain rock but, at first, couldn’t feasibly or economically recover it. However, there was a solution. Fluiddriven fractures could be formed at depth in the oilfield borehole and extended into targeted aquifer formations. Frac’ing or Fracking technology significantly increased the surface area to recover the petroleum resources, and is now commonly used by the oil and gas industry to access “unconventional” natural gas deposits trapped in shale, coalbed, and tight-sand formations. Add in the ability to drill horizontally within the right formation and the oil and gas industry exponentially improved petroleum recovery in that formation. Even for the geothermal industry, the cat is already out of the bag. Many geothermal energy developers have already begun to see the potential of similar technology. Projects in Soultz France, Cooper Basin, Australia, and Newberry in the US have all used pressured fluids to increase permeability and to increase heat recovery. In hard-rock and volcanic environments, manmade hydraulic fractures use internal fluid pressure to help open pre-existing weakness in the rock structure. The new fracture is, then, typically maintained by introducing a proppant (such as sand, ceramic, or particulates) into the injected fluid. Projects that were once left economically wanting now have the potential for increased profitability. And, those in the renewable energy industry understand that slight improvement could take a project into the realm of financial viability.

This technology is not without its’ detractors, however. Environmental and community groups have brought some of the technology’s downfalls into the public spotlight. Fresh water contamination, induced seismicity, and the toxic nature of some fracking fluids are just some of the concerns. To continue to be part of a clean energy solution for our planet, the geothermal energy developers adopting this technology need to closely monitor and responsibly deal with any and all concerns, real or imagined. The industry needs to ensure that any individual fracking program does leave a “black eye” on the geothermal industry as a whole. At the core, our planet is over 5,000°C, is approximately 6.3km thick, and continues to produce vast amounts of heat. To put this in perspective: the heat stored in only the top three kilometers of the continental crust is equivalent to the energy consumed by mankind for some 100,000 years at the present rate. At a depth of 10km, the heat in the of the earth’s crust contains 50,000 times as much energy as found in all the world’s oil and gas reserves combined. In 2007, a US Department of Energy sponsored study, completed by independent experts led by the Massachusetts Institute of Technology (MIT), concluded that geothermal energy could provide 100,000 MWe or more in 50 years by using advanced EGS (enhanced geothermal energy) technology. The problem is clearly not a lack of heat (we have billions of years of heat available), it is getting that heat out of the ground cost effectively. The more the industry can research and test this technology in geothermal applications, the more this technology can be implementing to improve the economics and decrease the project risks of geothermal energy development. Love it or hate it, fracking technology has the potential to forever change how the geothermal energy industry extracts its’ heat resource.

Enhanced Geothermal Clean energy’s Holy Grail By Tom Rand, P.Eng, PhD

E

veryone knows we mine the heat of the earth for clean energy. We use lowgrade heat found everywhere beneath our feet to heat and cool our buildings, and the high-grade stuff in hot aquifers to make electricity. That’s old news. There’s a new game in town, however, and one that holds considerable promise. The guys from Google are in on it. The Australians are drilling like mad for it. It’s the one clean energy that could bump coal off the podium. Tomorrow’s geo is called Enhanced Geothermal Systems (EGS), and it’s based on the simple idea that high-temperature heat can be mined pretty much anywhere—if you only drill deep enough. In most of the world, the ground that’s six miles (10 km) beneath our feet is dry, but as hot as the hottest aquifer. That heat can be mined, brought to the surface, and used to generate electricity. The potential of geothermal energy once EGS is brought into commercial operation cannot be overstated—it is simply colossal. A recent study by the Massachusetts Institute of Technology (MIT) noted that the total geothermal energy available within six miles (10 km) of the surface is 130,000 times the entire US energy needs. Obviously, not all of it can be tapped, but even conservative estimates of recoverable energy indicate there’s between 3,000 and 30,000 times our energy needs down there. This isn’t intermittent power like solar or wind—this stuff is available all day, every day, all year round.

Soultz is not the only project. Drilling has started at several locations in Australia, including Paralana and a massive project at Cooper Basin. There has been an operational plant in Landau, Germany since 2007 that produces enough power for more than 6000 homes. Sweden and Japan are in on the action. The first commercial plant in the US, partly funded by the US Department of Energy, is planned for Desert Peak, Nevada. The guys from Google see promise. They’ve invested in Potter Drilling, which has invented a faster, cheaper way of drilling using super-heated water to fracture the rock. There are pitfalls. EGS is still in early stages of commercial development, and there remain technical uncertainties related to the geophysics of deep-earth rock fracturing, water flow, and loss rates. We need to know more about using and expanding natural fissures and cracks in deep rock formations, and about how that structure will respond to having large amount of heat extracted over time. In Basel, Switzerland, there were reports of seismic disturbances when an EGS system was activated, and we must certainly mitigate that risk. But these are the sorts of challenges the engineering and scientific community solve all the time. The real barrier to widespread deployment of EGS is economic incentives.

How does it work?

Drill down a long way—2.5 miles to 6 miles (4 km to 10 km)—to reach hot rock approaching 400°F (200°C). Drill another hole, some distance away. Pushing water down the first hole at high pressure fractures the rock between the two holes. To mine the heat, pump liquid down one hole, through the volume of rock, and up the other. Grab the heat at the surface and use it to generate electricity. Sound difficult? We already drill miles down in deep oceans (think BP and the Gulf) to get at small pockets of oil, and we fracture rock all the time to get shale gas. EGS is the same expertise. To get a sense of how much energy is there, just imagine a 70,000 tonne pile of coal. Extracting enough heat to lower the temperature of a piece of rock 1 km3 in volume by just one degree, gives as much energy as you get burning that pile of coal. That’s enough to power 14,000 homes for a year. An EGS plant that powers 100,000 homes takes up less than a square-mile (2sq km), and uses a 5 km3 underground reservoir of rock. When that plant runs out of heat, which would happen every six years or so, then you simply drill new holes a few miles away. The earth gradually reheats the original area. This is truly renewable energy. The real magic of EGS is you can drill for it pretty much anywhere. London, Adelaide, Toronto, or New York, it doesn’t matter. What has been done so far?

Starting with experimental projects in the 1970s at Los Alamos National Laboratory, US, and in 1980’s in Cornwall, UK, methods were developed to make fractures in hot, dry rocks way below the surface. A full-scale international collaboration is underway in Soultz, Germany. Small, experimental holes 2.2 miles (3.5 km) deep were drilled in 1997, and the site has been expanded to a full-scale pilot project using three holes 3.1 miles (5 km) deep. Water pumped into one hole emerges from the other at about 400°F (200°C). A power plant big enough to power 1500 homes is in operation.

How do we get it going?

MIT figures EGS needs a $1 billion R&D “kick-start” (spread over 15 years) to establish the engineering know-how. At that point market forces would take over. They estimate that, by 2050, enough EGS systems would be built in American soil to satisfy 100,000,000 homes, or 10% of the total expected US electrical demand. That’s a conservative estimate of the potential, since it relies heavily on market forces and a natural rate of uptake. With a price on carbon, and access to low-cost debt, adoption rats would be much faster. Want to replace coal? Start drilling EGS holes beside every existing coal plant. Replace the furnace with a heat-exchanger. Keep the rest of the infrastructure—turbines, transmission lines, etc. If the input cost of coal plus the carbon liability is more than the monthly bill for the EGS plant, then it’s a nobrainer. Coal plant owners would come onside. There are no magic bullets on the clean energy front; every technology comes with technical and financial risk, particularly when it comes to project finance. But on a straight-up energy front, EGS seems to be as close to being a holy grail as one can find. In his recent book, “Kick the Fossil Fuel Habit: 10 Clean Technologies to Save Our World,” Tom Rand advocates thinking big—as big as we now think of fossil fuels. To spark the imagination, he asks: ‘What do you get for a trillion dollars?’ A trillion dollars of EGS gets around 400 GW of capacity, capable of replacing North America’s entire coal infrastructure. More information and an interesting video relating to this story can be found at www.kickthefossilfuelhabit.org.


Cooling solutions for energy management

Single-well engineered geothermal system GTherm SWEGS incorporates numerous unique and proprietary features that resolve many of the serious problems associated with EGS and transforms geothermal into a broadly deployable, non-polluting, and cost-effective approach to renewable energy. GTherm proprietary “closed-loop� technology allows for the mining of geothermal heat from hot dry rock (HDR). GTherm SWEGS eliminates the need for hydraulic simulation, and the need to drill injection and production wells. SWEGS is based on a unique HeatNest, which integrates a downhole heat exchanger with heat harvesting appendages in a specialized high-thermal conductivity grout to maximize heat transfer from the geothermal resource. The heat transfer fluid is pumped downhole through the HeatNest and back to the surface where it is converted into electricity by either a standard binary cycle generator or an alternative low-temperature generator, depending on the thermal resource temperature. This environmentally benign, closed-loop approach is not only simpler and more controllable than the combination of injection wells, production wells, and artificial reservoirs used in existing EGS, but it also eliminates the massive maintenance issues associated with bringing corrosive, underground fluids to the surface for transformation into electricity.

Industrial Cooling Solutions has simplified energy management for cooling tower applications with its Energy Management System (EMS) controller. EMS controls are typically used whenever ambient conditions and plant system requirements allow for reduced power output. The EMS software and quick-start set-up parameters allow the operator easy access to set control values for a wide range of applications. The Energy Management System will automatically adjust cooling tower operation conditions from single cell to multiple cells as the process variables change, while still maintaining optimum cold water process system performance and protection. By matching cold water demand directly to the process requirements, small variations in the process can be corrected rapidly by an Energy Management System, rather than by other control forms. Any reduction in speed achieved by using an EMS has major benefits in reducing gearbox wear, particularly in bearings and seals. The EMS controller lowers system costs by eliminating large control steps in the cooling tower system. Savings of 20% to 50% can be achieved, depending on the application, by adjusting fan speed to match process cold water demand. Industrial Cooling Solutions | www.h2ocooling.com

Biomass Supply for Electricity Generation By David Benson (left) & John Eustermann (right)

W

ood and other organic materials have been used as fuel for the generation of energy for decades—in fact, for about the last 1.5 million years. Recently, utilities, developers, and stakeholders have recognized the environmental and economic benefits of using these materials, such as forest slash, wood residue, waste wood, and certain non-food energy crops (herein, referred to as “biomass”), as fuel for energy generation. The development of a biomass energy facility is heavily dependent on the ability to economically deliver to the facility the quantity and quality of biomass necessary for a project. This article presents a few of the issues the developer of a biomass electricity generation project should consider to ensure a long-term supply of biomass. Although it doesn’t focus on other organic materials, such as municipal solid waste (MSW) or energy conversion methods like biomassto-liquid fuels, many of the issues and solutions discussed are relevant to such projects.

Production & logistics. Biomass production and logistics require significant upfront attention by developers, suppliers, and financiers. Production issues range from cultivating biomass resources to establishing the rights needed to harvest or collect biomass in a manner consistent with current production paradigms, while also addressing sustainability and ensuring the health and safety of the environment and those engaged in the activity. For logistics, the primary challenge is a lack of mechanized harvesting equipment and the means to efficiently and economically transport biomass from its source to the processing facility. Unlike agricultural products, MSW, or biosolids that have well-developed supply mechanisms, the infrastructure for delivery and storage of biomass for energy generation often needs to be custom built and is not cost effective. This lack of infrastructure introduces additional costs and risks into a project that, unless managed appropriately, can have a detrimental effect on the ability to arrange financing. Generally, the success of a biomass facility requires the facility secure long-term access to the necessary biomass feedstock on a cost-effective basis. Project data & biomass specifications. Given the importance of biomass supply to the success of a project, a developer must obtain a detailed biomass supply study addressing the quantity and quality of feedstock needed for the particular conversion technology being used. Such a study provides a developer and the prospective project financing parties with modeling data for confirming: 1. Sufficient supply; 2. Siting the facility; 3. Biomass suppliers and harvesters (which may be separate parties); and 4. A project’s overall viability and financeability. In obtaining such a study, a developer should engage in the appropriate levels of due diligence with respect to those third-party consulting firms offering such services, as a great deal is riding on the results. The quantity specifications are a function of the size of a facility, the conversion technology, and the economically available quantities of biomass that can be delivered to the facility on a long-term basis. The quality specifications, though a function of the conversion technology, may also include the following categories based on a dry basis and as received: • Heat of combustion; • Ash content; • Particle size; • Moisture content; and • Selected elemental content.

Biomass that fails to meet the necessary specifications should be rejected by the buyer or subjected to a reduction in price as set forth in the supply agreement. Turning biomass into power generally involves either the combustion or gasification of biomass, which energy (gasification involves another step of combusting the biogas) is then used to produce steam to generate electricity from a turbine. With an understanding of the conversion technology and a comprehensive biomass supply analysis, a developer can identify the needed terms in the supply agreement and, hopefully, figure out the project’s economic model. Biomass pricing. The developer should consider several factors when pricing biomass including current and projected disposal costs, transportation distances, volumes (to be made available or delivered), a reliability quotient, quality specifications, and processing costs. To create some pricing consistency and objectivity, certain industry participants are working to create biomass indices based on prior reported transactions. Until such mechanisms become available, creating a pricing model is complex and often involves combining a number of factors listed above with currently indexed energy commodities. Developers needing to formulate a biomass pricing scheme in a long-term supply agreement should not underestimate the value of engaging qualified experts. Biomass supply wrap arrangements. Even if a developer has a solid biomass supply study, solid economics, and reliable suppliers, lenders may still be reticent to finance a biomass project due to perceived market risks and uncertainties that can adversely affect the supply of biomass to the project. Similar to an EPC wrap, lenders would like the same risk protection for the biomass supply to a project. Such an arrangement is being considered and some have recently been formalized, such as the arrangement offered by Ecostrat of Ontario Canada for woody biomass. The goal of such a supply wrap is to reduce the supply and pricing risk for biomass by guaranteeing supply availability and pricing (often fixed to a mutually recognized forestry pricing index) for 10-year to 15year terms. The pricing under such instruments are, of course, subject to certain escalators such as the cost of diesel, inflation, distance (per-mile escalator for hauls in excess of an agreed upon upper limit), and stumpage. Furthermore, as expected, a developer will need to consider the associated cost of implementing such an instrument (some premium on per bone dry ton basis). Naturally, in the case of today’s current debt situation, absorbing such costs may be the only option to arrange financing. Biomass supply present unique challenges for developers. The wise developer is thoughtful when arranging the supply of biomass to meet a facility’s needs. He or she must carefully consider the reliability, costs, and risks in the overall supply chain to properly analyze a project’s economics. The developer should expect to work continuously with suppliers, processors, and transporters to address the inevitable issues and to develop new supply options. Once armed with the appropriate data, a developer is in a position to define the duties and obligations of the counter-parties in the supply, harvesting, and delivery agreements. Finally, implementing a biomass supply/pricing wrap may be an effective method reducing biomass supply and pricing risk to obtain financing.

Portable Fuel Feed System for burn testing of alternative fuels The Portable Feed System (PFFS) offered by Jeffrey Rader Corporation is specifically designed for on-site alternative fuel testing. The portability of these units offers the convenience of a testing system capable of being relocated as needed for testing at different locations and under different conditions. Used for testing boilers, kilns, or other processes, this system allows the owner/operator the greatest flexibility for verifying boiler performance with different materials. Testing materials prior to investing in a large material handling system for a boiler or kiln is an effective and economical way to ensure process performance and emission levels based on actual site conditions, fuel types, and feed rates—something that varies widely with each location and fuel used. This system is skid mounted with a hopper system for storing and metering the material. A twin screw can feed the material directly into a pneumatic system or, when greater accuracy is required, the twin screw feeds to a weight-belt feeder. This material is then metered into a special rotary valve that feeds the pneumatic system. The material is pneumatically blown directly into a boiler/kiln through a port on the burner, or into a pulverized fuel line prior to the burner. When direct pneumatic injection is not an option, and a mechanical feed is used, the material is discharged through a cyclone before entering the mechanical feed system.

Organic biomass into ethanol fuel E-Fuel is pleased to announce its latest innovation, the E-Fuel MicroFusion Reactor, a disruptive technology that empowers users to process all forms of cellulosic waste into sugar water—the key ingredient for ethanol fuel. The E-Fuel MicroFusion Reactor makes available the virtually limitless supply of cellulosic waste materials as a suitable, renewable candidate for ethanol fuel production. Annually, in the US alone, almost one billion tons of organic waste material is available for processing by the MicroFusion Reactor into 100 billion gallons of fuel at little or no cost. Converting this waste into fuel reduces the burden on landfills where most waste is currently destined and the detrimental effects on the environment. The MicroFusion Reactor operates as a continuous process. Every two minutes the cellulosic material in the reactor chamber is completely processed and ready for fuel processing. The method of wood hydrolysis dissolves any wood or other cellulosic agricultural material in a manner that is residue free. Waste output is completely eliminated. The waste output is comprised of: 1) sugar water; and 2) lignin powder. The sugar water is fermented by the MicroFueler into ethanol. (The lignin is a valuable substance used in the pharmaceutical industry as an ingredient in various cancer-fighting drugs among other things.) The reactor eliminates the costs and complexities associated with commercial gasification, aerobic digester, enzyme, and acid pre-processing of cellulosic material typically used in traditional ethanol fermentation processes.

A New Take on Algae Algae offers one of the best opportunities for future biomass production. Algae growth can actually double every day. However, current ways to process algae are not very well executed. There are better ways to utilize algae because it requires UV, warm water, and CO2. What’s required is a process whereby power plants and process plants utilize warm, cooling tower water to grow algae. CO2 would be taken from the combustion process, as it is a natural byproduct, and be injected into the algae growth chambers to help stimulate growth, while also reducing CO2 emissions. Failure of most algae production facilities stems from attempts to extract oil from the algae. This can be counteracted by filtering algae and injecting the entire de-watered algae into a boiler to burn. The oil and the algae fiber are both combustible and burn together. Both process plants and energy plants would get credits for their clean technology, plus they would be reducing their CO2 emissions and generating a natural fuel source. This is a possible process with positive benefits.

Increasing the Economy of Biomass Flow Control By Todd Loudin

D

uring the last decade the importance of environmental awareness has risen dramatically and industrial operators must consider the consequences of their actions on a larger scale. It is essential to reduce carbon dioxide emissions, which can be done in several ways, thanks to the multitude of technologies now available and offered by environmentally oriented companies and authorities. Although biomass technologies have been explored for years, only recently have these technologies become implemented for practical use. For instance, one of the most promising and most cost-efficient solutions is to use biologically decomposable fuel-based ways as a method of producing energy. The improved efficiency coefficient has enabled bio-energy to become a serious competitor to oldfashioned, non-renewable energy technologies. Today, it is possible to receive ready-made products and services applicable for biopower-related industries, which makes the “flow control” at a facility utilizing biomass essential. Biomass is not only related to biofuels, however. It is much more than that. Biomass includes plant or animal components used for the production of fibers, chemicals, fertilizers, or heat. Biodegradable wastes can be burned as a fuel in incineration plants. The combining factor of biodegradable materials is the composition, which includes different extractives, ash, lignin, minerals, sulfur, nitrogen, and solid particles.

Processing biomass

With solids and chemicals, biomass creates big challenges for process equipment such as valves and pumps. Typically, problems are related to the wearing of sealing or moving metal parts, which then leads to malfunction and can prevent the material from flowing, causing pipeline blocking. To solve this challenge, products are offered wherein no moving parts, metals, or seals are in touch with the medium. The only parts contacting the medium are the valve sleeve and the pump hose made from materials resistant to acid, alkali, fat, chemical, and solids. There is also a suitable sleeve or hose for each application, equipped with abrasion resistance. The promise of sustainable development

The introduction of new technologies in terms of making biomass handling more efficient is only one of the actions many companies have taken to uphold sustainable development. Manufacturing, supplier control, and material flow processes must also be taken into account. Using renewable and certified packing materials and methods, and avoiding environmentally hazardous chemicals is also all apart of maintaining positive flow control. Authorities have guided companies to use the best available technologies when they are increasing the production or building new production facilities.

Co-Firing Wood Pellets for Power Generation By Mike Curci

S

ince the 1800s, the United States has been using biomass to generate power for use in homes and manufacturing. Beginning in the late 1980s and early 1990s, European countries began conducting co-firing tests utilizing wood pellets. Today, there are numerous case studies, along with a multitude of generating facilities that use wood pellets to offset the usage of coal. Hasselbyverket in Stockholm has been using 250,000 tons of pellets a year since 1993, and Electrabel is currently co-firing using 300,000 tons a year at its Rodenhuize, Belgium power plant. The United States does not have a generating facility that utilizes wood pellets to generate power, yet the US is capable of producing over six million tons of pellets annually. Much of the US pellet production is currently exported to European countries for use in generating facilities. Recently, plans have been announced in the States for repowering or retrofitting facilities to be powered with wood pellet fuel. However, many of these projects are currently on hold or have even been completely abandoned due to pending EPA regulations. To date, only co-firing with pellets tests have been conducted within the US. The Europeans have led the bioenergy power generation boom for the last 20 years, just as the Chinese led the technology boom. Some US utilities will point out the few problems co-firing wood pellets present such as unit fouling, effects on SCR Catalysts, carbon neutrality, supply chain and, most commonly, the economics. Wood pellets provide more benefits than problems, however, and are a more economical choice for renewable energy as compared to wind or solar. Co-firing can be achieved with minimal capital investment and quick implementation, while simultaneously creating local jobs. Biomass repowering is more cost competitive since it makes use of existing plant equipment. Unlike wind and solar, co-firing is a direct replacement for coal generation capacity, which can be dispatched. The environmental benefits of co-firing, including a reduction in sulfur, nitrogen, and mercury emitted from generating facilities, have spurred the testing and implementation in European countries. Currently, the majority of co-fired boilers around the world are based on pulverized coal (PC) or circulating fluidized bed (CFB) technology. Both technologies exhibit high conversion effi-

ciency, however, CFBs usually offer lower furnace emissions and higher fuel flexibility. Implementing co-firing boiler technology can be ranked in the following order from no capital investment to high-level capital investments: co-milling, direct injection, unit conversion and, lastly and most expensively, Greenfield or Brownfield development. Co-milling presents lower capital costs, but also a lower energy yield when co-firing with wood pellets. Direct injection requires a capital cost of $500 to $700 a kilowatt, but also results in a higher energy yield when compared to direct milling. Unit conversion is another option, but requires a higher capital cost of $1,400 to $2,000 a kilowatt and new industrial boiler MACT policies must be seriously considered. State Renewable Portfolio Standards (RPS) or a Renewable Electricity Standards (RES) are the greatest driving factor for utilities that seek the opportunity to co-fire. Utilities have many options for meeting those standards such as with wind, solar, or biomass. Depending upon boiler technology and whether the project will be co-milled or use direct injection, the cost of meeting the RPS can be significantly lower. When utilities look to conduct co-firing tests, they must take into consideration seven key items: 1. Storage: Pellets are unable to be exposed to the elements like coal piles and must be kept dry; 2. Milling (sizing): Pellets must be reduced in size through the use of ball mills when being introduced into a pulverized coal boiler; 3. Delivery: Existing infrastructure at generating facilities was designed for coal and not pellets— therefore, consideration must be given to getting the pellet fuel to the boiler; 4. Slagging, Fouling: Woody biomass, as compared to herbaceous biomass, is less problematic in terms of fouling; nevertheless, consideration still must be given to prevent it; 5. Emissions: Fuel NOx can be higher if the boiler is not properly tuned; 6. Health & Safety: Off-gassing is a concern in wood pellet storage causing sickness and sometimes even death; 7. Ash Sales: Fly Ash containing biomass does not meet ASTM standards for use in concrete, so it must be land-filled.

Finally, it is apparent that fuel consistency for power generation is wanted by utilities. And, since pellets are uniform in size, shape, moisture, density, and energy content, they are a feedstock that must be considered. Nearly all forms of biomass have some hurdle that needs to be overcome, but the benefits drastically outweigh any problem biomass has—especially when using pellets. Co-firing wood pellets for power generation makes sense on an environmental, renewable energy, energy independence, and rural economic level. Pellets are a viable feedstock for power generation and should be utilized as such. Mike Curci is the chair of the Pellet Fuels Institute Commercial Fuel Committee.

Global Ocean Energy Prospects Boosted by Established Hydro & Wind Players Surge of prototype projects could signal dramatic growth in ocean energy industry

T

he global ocean energy sector is at a turning point, with over 45 wave and tidal prototypes expected to be ocean tested in 2010 and 2011, after only a dozen were installed in 2009, according to a new IHS Emerging Energy Research market study. If these initial projects are successful, the global ocean energy project pipeline is poised to begin scaling. IHS estimates that more than 1.8 GW of ocean projects in 16 countries are currently in the pipeline. The ocean energy industry’s recent development has attracted a slew of established energy companies with renewable growth ambitions, including European utilities and global technology suppliers—many with hydro and offshore wind experience. Boosted by government and policy support, the UK is currently the world’s leading market for ocean energy, with 300 MW of projects in the pipeline seeking to be installed over the next five years. The UK government hopes to add 1.3 GW by 2020, driven by its need to meet legally binding 2020 renewable targets. Ireland, France, Portugal, South Korea, and Australia are also key ocean energy markets and will remain the industry’s primary focus for the next decade, according to the study. Of the various forms of ocean energy, tidal energy is poised to mature first, with the promise of providing predictable, lower-cost electricity and a standard design. Tidal is attracting major original equipment manufacturers (OEMs) into the ocean energy industry’s supply side. “The strong synergies between tidal turbine manufacturing and the hydro power industry have attracted major power sector OEMs,” said IHS senior renewable power analyst Marianne Boust. “Over the past two years, all three of the major hydro power turbine vendors— Andritz Hydro, Alstom Hydro, and Voith Hydro—who account for over 80% of the total global hydro turbine supply, have jumped into the tidal sector.” “Large hydro players see tidal as a synergistic growth opportunity, with at least 150 GW of installed capacity potential globally. Traditional hydro players are critical to catalyzing faster development and commercialization of the tidal industry,” added Boust. Greater involvement by large OEMs will help the ocean energy industry overcome its technological challenges and drive down costs. Several key players active in Europe’s scaling offshore wind industry are also turning their attention to ocean energy as they scale their renewable portfolios. Major European utilities have an extensive presence in offshore wind, and each has broadened its offshore activities to include ocean energy. While a few have taken equity stakes in ocean technology promoters, most are now shifting to fund project development joint ventures. “Continued policy support and the entrance of established energy players competing alongside maturing technology promoters signal the ocean industry’s potential to advance along the learning curve and to emerge as a scalable renewable energy alternative during the next decade,” Boust concluded. Global Ocean Energy Markets and Strategies: 2010-2030

Released in October 2010, this 228-page study analyzes the potential size and timing for ocean energy scaling, outlines emerging competitive strategies of wave and tidal project developers, and evaluates the strengths and weaknesses of competing wave and tidal technologies. IHS is a source of information and insight in pivotal areas that shape today’s business landscape: energy, economics, geopolitical risk, sustainability, and supply chain management.
