30 FEATURE Isobutanol to the Rescue The U.S. Coast Guard is testing the feasibility of powering its fleet with isobutanol gasoline blends. By Chris Hanson



Brothers in Arms The U.S. military is the largest single user of energy in the world. Its five branches consume every type of energy product available, and in staggering quantities. In a 2010 Global Green USA report, author Schuyler Null notes that if the U.S. military were a country, it would rank 54th in the world in total energy use, edging out developed countries like Portugal, Qatar, Israel and North Korea. TIM PORTZ Add to that the military’s strategic VICE PRESIDENT OF CONTENT & EXECUTIVE EDITOR objective to grow its use of able energy to 25 percent by 2025, and the picture that emerges illustrates the U.S. military as being one of the hottest markets for renewable energy in the world, with needs for abundant electric, thermal and liquid fuel energy. The Biomass Magazine team has been watching this sector develop the past two years and has published news stories in print and online the mandates, strategic initiatives and military exercises that have marked the growth of renewables in the armed forces. When we built the 2013 editorial calendar last fall, we knew it was time to dedicate an entire issue to biomass energy in the military. We thought November would be a great time to honor the men and women, in and out of uniform, driving these initiatives. The mix of technologies featured in this issue demonstrates the variety of locations our armed forces operate near, as well as the varying biomass resources available in each region. Sue Retka Schill’s article “Fighting the Good Fight” (page 17) catches up with the Oregon National Guard as it explores the opportunity for local forest biomass resources to simultaneously move away from nonrenewable petroleum heat energy while reducing the fuel load in the state’s forest acres. In his feature “Isobutanol to the Rescue,” (page 30) staff writer Chris Hanson details the U.S. Coast Guard’s corn-derived isobutanol tests, which the USCG hopes can prove the fuel can perform in a challenging marine environment. Finally, Anna Simet’s article about the landfill gas operation at the U.S. Air Force’s Joint Base Elmendorf-Richardson near Anchorage, Alaska, (page 24) highlights why landfill gas is increasingly earmarked as a reliable source of baseload quality power for military bases. The U.S. military has a long history as an incubator for innovation, so its continued push into renewable energy production and use is not surprising. The mandate now, for the biomass industry, is to ensure biomass has a proportionate seat at the table as the military’s energy future is boldly reimagined.

National Bioenergy Day: Spotlight on Biomass BY BOB CLEAVES

Oct. 17 marked the first-ever National Bioenergy Day. On and around that day, 24 events were held in 13 states—and one in Canada—to raise awareness about biomass and the larger bioenergy industry. We were honored that Biomass Magazine sponsored the initiative alongside Biomass Power Association, in addition to Biomass Thermal Energy Council, American Council on Renewable Energy, Pellet Fuels Institute, Forest Landowners Association and U.S. Industrial Pellet Association. In planning National Bioenergy Day, we wanted the focus to be on the role bioenergy plays in communities. The goal was to bring audiences, ideally people who benefit from bioenergy, to biomass facilities to witness firsthand what goes on. National Bioenergy Day activities drew in audiences from academia, government, media, and local communities. Visitors were able to learn about biomass electricity production, small-scale thermal heating, pellet manufacturing, managed forestry and the carbon cycle. They listened to lectures at universities and saw an anaerobic digester at work. I attended ReEnergy Holdings’ event at its Livermore Falls facility in Maine, where elected officials joined local residents for a tour of the facility and a presentation on the benefits of biomass. I’d like to highlight a few more National Bioenergy Day events:

• New York Biomass Energy Alliance facilitated a day-long event in northern New York where guests could visit a school district that is using woodchips for heating to save $110,000 per year, a 22 MW biomass facility, a shrub willow farm, and a wood pellet manufacturer. • In Michigan, the state biomass trade association joined forces with timbermen and forest products associations to hold a two-day event for visitors to tour a biomass facility, a forest products manufacturer, and a timber harvest/chipping operation. • A whistle-stop tour in the Southeast took a biomass digester to several college campuses in Tennessee, Alabama and Georgia to demonstrate small-scale heat and energy production. Additional events were held in California, Minnesota, Maine, North Carolina, Mississippi, Connecticut and Oregon. National Bioenergy Day was an event that truly showcased our industry, and the environmental and economic benefits it provides across America. We look forward to an even larger and more comprehensive National Bioenergy Day 2014. Author: Bob Cleaves President and CEO, Biomass Power Association





WIN-WIN-WIN: Flanked by dignitaries including Maj. Gen. Mark A. Milley (in uniform), former commander of Ft. Drum, and New York Gov. Andrew Cuomo (far right),ReEnergy CEO Larry Richardson discusses the Black River Project’s local economic impact.

Mission Alignment ReEnergy has opened a new front with its Black River Project at the Army’s Ft. Drum, N.Y. BY TIM PORTZ


t. Drum is a U.S. Army post in upstate New York, positioned south of the Canadian border just beyond the eastern reaches of Lake Ontario. The 107,000-acre facility is home to the Army’s 10th Mountain Division and has been utilized as a training facility since its first acres were purchased over 100 years ago. Situated inside of the fort’s perimeter is a power plant that its new owner and operator, ReEnergy Holdings LLC, is hopeful will soon be among the Department of the Army’s growing list of renewable energy success stories. The facility, which ReEnergy has dubbed ReEnergy Black River, was designed and configured to burn coal but was idled by its former owners Energy Investors Funds Group in 2010. While the facility no longer delivered the returns EIF wanted, it fit perfectly with ReEnergy’s business model. In December 2011, the 12 BIOMASS MAGAZINE | NOVEMBER 2013

company purchased the plant from EIF and began an extensive retrofit project. Larry Richardson, CEO of ReEnergy, notes that EIF did well to preserve the value of the idled facility. “The prior owner had really done a good job of laying up the facility,” he says. “Certainly the key elements of the facility, the three boilers and the one turbine generator, had been laid up in a manner where the quality of those items was largely preserved.” Despite the facility’s preserved condition, ReEnergy’s additional investments into the Black River station topped $30 million with significant investments made to the facility’s fuel receiving and distribution infrastructure. “Where coal had previously been delivered by rail, we had to build the infrastructure to accept the biomass by truck, installing truck tippers as well as

a new fuel conveying and storage and processing system,” says Richardson. The plant’s initial design to deliver not only power to the grid but also hot water to an onbase district heating system was scuttled early in the life of the project. Apart from where it sat, the facility had no relationship with the base, with all of its produced energy being sold over the fence and onto the waiting power market. Richardson and his team at ReEnergy hope to change all that. At press time, ReEnergy is waiting to hear from the Department of the Army and the Defense Logistics Agency on their response to the Army’s request for proposal for enough renewably produced power to support the base, about 28 MW. “Without question, the location of the power plant inside the fence at Ft. Drum presented a great opportunity to provide secure, renewable energy to Ft. Drum on an ongoing basis, particularly-




SECURE, RENEWABLE AND BASELOAD: ReEnergy’s Black River Project is the largest asset in its power portfolio and the first on a military base.

FUEL CHANGE, INFRASTRUCTURE CHANGE: Originally designed to receive its coal via rail, ReEnergy made significant investments in wood-receiving infrastructure at the Black River Project, including these two truck dumpers.

since the plant had never delivered electricity to Drum in the past. It was a significant consideration in our investment decision and the alignment with the Department of Defense and the Department of the Army’s initiatives related to secure energy and renewable energy. We felt the alignment was great and timing was right to make this happen,” says Richardson.

Regardless of the Department of the Army’s final decision, the Black River project fits well into the growing power and fuel processing portfolio amassed and operated by ReEnergy. Operating predominantly in the Northeast, ReEnergy owns or operates 13 different facilities in six states with a total output of 325 MW, directly employing over 300 people.

Making environmental performance a core element of its operating philosophy, ReEnergy recently achieved certification from the Sustainable Forest Initiative, which verifies that its biomass procurement practices adheres to stringent, responsible forestry practices. Additionally, among the investments that ReEnergy made at the Black River Project was a new cooling tower. Before ReEnergy’s retrofit, water was simply taken from the Black River, a mile south of the facility, and process water was discharged back into the same river, resulting in a significant thermal plume. Richardson points out the significant advantage the cooling towers bring to the facility noting that it “allowed [ReEnergy] to reduce both the withdrawal of water from the Black River and the thermal discharge back into the Black River by about 90 percent.” Rounding out the facility’s forward-thinking operating strategies is a unique feedstock program being developed with assistance from the Biomass Crop Assistance Program. Hoping to leverage the marginal land in the vicinity of the Black River station, farmers are being recruited to establish shrub willow. Nearly 1,100 acres of marginal land in a three-county area will be planted with shrub willow and will eventually contribute to the facility’s fuel needs. The Black River project in many ways represents a series of firsts for ReEnergy. The facility is ReEnergy’s largest asset when measured by output, its first coal-to-biomass conversion, and the first company-owned asset that sits on a military base. Richardson is hopeful it won’t be ReEnergy’s last. “We definitely see an opportunity to replicate this business model at other military bases around the country,” he adds. “There is no question that the success here should be a differentiator for us as we pursue other opportunities around the country. That is why we are hopeful we will be awarded a contract here and really be a part of one the early success stories in the Army’s renewable initiatives.” Author: Tim Portz Executive Editor, Biomass Magazine 701-738-4969

Fighting the Good Fight

Biomass thermal coincides with the Oregon Army National Guard's energy security goals and has larger-picture benefits such as aiding wildfire reduction and job creation. BY SUSANNE RETKA SCHILL


ellet boiler heating systems will help the Oregon Army National Guard meet its ambitious goal of net zero energy at all of its 53 installations statewide by 2020. ORARNG, which volunteered to participate in broader initiative of 19 pilot projects at U.S. Army sites across the country targeting net zero energy, water and waste, has four thermal pellet heat projects planned at National Guard sites. These projects offer a couple of benefits for ORARNG, says Lt. Col. Ken Safe, construction and facility management officer and Net Zero Energy project lead. “It allows us to reduce our energy cost, because the sites where we’re doing the conversion are on propane,” he says. “The more substantial benefit for the net zero program is it allows us to get off fossil fuels and go to renewable energy.” In addition to reducing energy costs and aiding sustainability goals, the net zero program has energy security and independence goals as well. A net zero energy installation is one that produces as much energy onsite as it uses over the course of a year. ORARNG expects that 65 percent of the reduction from its 2003 energy baseline will come from improved energy efficiency. And, while the unit is looking at multiple renewable technologies including solar, geothermal, wind and wave energy, wood-to-energy rates high for thermal heat since it can be produced on the site where it is consumed, Safe points out, compared to renewable electricity that is transported or given renewable energy credits as offsets.





WARMING TRAINEES: The Biak Training Center, Powell Butte, Ore., will use a pellet boiler system to heat 20,000 square feet in a simulation center, classroom and administrative building.

TARGETING CLUSTERS: Oregon Army National Guard sites are centrally located for wood-to-energy utilization. In particular, the state would like to reduce the fire hazard in eastern forests.

Partnering For Pellets ORARNG has partnered with others in its planning efforts, receiving a $250,000 woody biomass utilization grant from the U.S. Forest Service in 2012 for design work, plus a $489,000 renewable thermal incentive from the Oregon Department of Energy.


And, the project has received funding from the U.S. Endowment for Forestry & Communities Inc., with one product being a case study done by Dovetail Partners Inc. on the lessons learned from aggregating multiple projects into one planning process. Energy efficiency consulting firm Tetra Tech Inc. is helping with coordination and review of

the project design and did the initial evaluation, which identified buildings and locations for possible conversion. Seven National Guard buildings at five locations were identified where biomassfired boilers would be a cost-effective replacement for propane heating systems. Buildings at three of the National Guard facilities already have hot water boilers installed, making the conversion to pelletfired biomass boilers relatively easy. The Burns Armory in Burns, Ore., is a typical older armory, a 12,000-square-foot facility built around 1954. The Biak Training Center in Powell Butte, Ore., will convert to a pellet system to heat 20,000 square feet in a simulation center, classroom and administrative building. Conversion at the Youth Challenge Program facility in Bend, Ore., housing an academy for at-risk youth, has a favorable payback compared to other facilities due to its high heating and domestic hot water use for 10 months a year. Biomass conversion will be a bit more complicated for the maintenance shop at the Central Oregon Unit Training and Equipment Site in Redmond. The 10,000-square-foot building with its high bays and a few offices currently has a direct-fired radiant heat system. McKinstry Essention Inc. was awarded the design-build contract in late September for the installation of the biomass pellet boilers, storage and handling equipment, as well as associated safety and efficiency systems. SolaGen Inc. is supplying the biomass boilers. The Burns Armory is the smallest system with one 150 kilowatt (kW) unit. Biak is slated for one 220 kW boiler and COUTES for one 540 kW unit. The Bend Youth Challenge Program center would use two units, sized at 220 kW and 400 kW. The Biak and COUTES projects have been funded and construction is expected to be completed in April, while the Burns funding request is pending approval. The four heating conversions will annually replace 58,551 gallons of propane with 183 tons of pellets to achieve $85,000 in savings each year. As project planning unfolded, plans for biomass utilization at the Umatilla Training expanded. Initially, the ORARNG was

PELLET¦ looking at utilizing three pellet heating systems for the dining hall, a barracks and a simulation center, but wanted to study the possibility of building a single system or even a combined-heat-and-power system. As investigation proceeded and more was learned about the Army facility’s future following the Base Realignment and Closure process, the ORARNG realized it could have as many 25 or 30 buildings for its use, with other buildings being transferred to an adjacent Native American tribe and county. Thus, a larger system is now being considered that would utilize wood chips for district heating and power generation. A second $250,000 WBUG grant was awarded for the design, plus a $50,000 Wood Energy Cluster grant from the Oregon DOE and USFS. The U.S. Army Corps of Engineers has recommended the project be ranked as one of the Army’s top-five priorities for funding through its Energy Conservation Investment Program. That project is expected to replace 258,910 gallons of propane used yearly with 2,004 tons of wood chips for an annual savings of $362,000.

reducing fire risks in overgrown forests, the state seeks to foster economic development and job creation in communities that have been impacted by the decline in forestry products, he adds, plus there is another long-term strategy. “Creating this opportunity to keep people working in the woods, to keep producing pellets and woodchips and other products locally helps us maintain that workforce so as these new markets and opportunities for more advanced fuels develop, we have the skills and infrastructure and people in place to take advantage of those opportunities and continue to grow that industry.” “It’s really exciting to feel like you’re part of a broader goal,” Safe adds. “We have a forest health situation in Oregon where we’re at risk of wild fires, and to some degree pine beetles and other insects with the congestion in forests. From forest health to jobs for local economy, both in the forest and the manufacturing of pellets all the way

to transportation, there’s a number of jobs added at the local level.” With the National Guard ultimately being a community-based organization, pellets are a good fit. As the gas heating systems in other guard facilities around the state reach replacement age, Safe says, he will recommend they take a closer look at biomass thermal heat. “We’ll be getting the net zero thermal renewable credit, as well as helping the local economy.” While replacing currently low-priced natural gas isn’t a cost savings right now, Safe points out that [the market] is hard to predict five or 10 years ahead. “I’ve been raising the question when I give talks about our Net Zero Energy program,” he adds. “Even as a backup system, the more, the better in my opinion.” Author: Susanne Retka Schill Senior Editor, Biomass Magazine 701-738-4922

Bountiful Benefits The multiple partners in the ORARNG project reflect the multilayered benefits being anticipated from the biomass energy projects. “Oregon was a pilot state for a wood-to-energy effort with the forest service,” says Ron Saranich, regional biomass coordinator with the USDA Forest Service. “Facilities that are eligible are all sited in areas where we wanted to do hazardous fuel reduction—basically east and central Oregon where the high threat of fire danger and overgrown forest is located.” Oregon is adopting a wood energy cluster approach, explains Matt Krumenauer, senior policy analyst for Oregon’s Department of Energy. “Right now the smaller projects that are able to offset heat load at facilities are very competitive and able to be developed with pretty good energy savings and other benefits. Clustering multiple projects in a given geographic area begins to develop the sort of demand that helps meet land management objectives.” Besides

EPA expands RFS definition of heating fuel

The U.S. EPA has published a final rule to expand the definition of heating oil under the renewable fuels standard (RFS). The amendment expands the scope of renewable fuels that can be used to comply with the RFS by adding an additional category of compliant fuel produced from qualifying biomass that is used to generate heat to warm homes or other buildings. However, renewable identification numbers cannot be generated for the new category of fuel oils if that fuel is used to generate process heat, power, or other functions. The original definition of heating oil included any No. 1 or No. 2 nonpetroleum diesel blend that is sold for use in furnaces, boilers and similar applications and contains at least 80 percent mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats. The expanded definition includes biobased fuel oils that do not meet the original definition but are actually used to heat homes and other facilities to control ambient climate for human comfort.

UC Davis READ facility breaks ground

CleanWorld has broken ground on an anaerobic digestion facility at the University of California, Davis. The UC Davis Renewable Energy Anaerobic Digester facility is under construction at the former UC Davis landfill in Davis, Calif. The facility represents the successful commercialization of a technology developed by Ruihong Zhang, a UC Davis researcher and professor. The biodigester will divert 20,000 tons per year of food waste from dining


halls, dormitories and local restaurants, agricultural waste and green waste out of Davis-area landfills. Biogas produced by the biodigester will be combined with gas captured from the landfill, generating 1 megawatt of power. In addition to electricity, the project will produce more than 4 million gallons of fertilizer and soil amendments. The UC Davis READ facility is expected to be generating power by December.

Ameresco Inc. recently celebrated the completion of its 1.4 megawatt landfill gasto-energy project at the Johnson Canyon Landfill in Gonzales, Calif. Ameresco designed, permitted, constructed and now operates the facility at the landfill, which is owned by the Salinas Valley Solid Waste Authority. Ameresco Johnson Canyon LLC has an agreement with SVSWQA to purchase landfill gas for use in its plant. Electricity generated at the facility is being sold to the city of Palo Alto under a 20year power purchase agreement. “We are thrilled to have partnered with the Salinas Valley Solid Waste Authority and the city of Palo Alto to provide residents with clean, renewable energy for years to come,” said Michael Bakas, senior vice president of renewable energy at Ameresco. “We have had a successful track record working with many counties and municipalities in California and across the nation to provide alternative energy resources, and we are excited that our project will help SVSWA and Palo Alto and its constituents to achieve their sustainability goals in a cost-effective manner.”

Anchoring Air Force Energy Goals Alaska’s first landfill gas-to-energy project provides the Joint Base Elmendorf-Richardson with seven times its renewable energy mandate per the Energy Policy Act of 2005. BY ANNA SIMET





LANDFILL GAS TO THE RESCUE: The JBER landfill gas plant generates 100 percent of Ft. Richardson's back-up emergency power.


he farthest north facility of its kind at 61 degrees latitude, the Anchorage Landfill Gas-to-Energy Project at the Joint Base Elmendorf-Richardson is the largest green energy project amongst the U.S. Air Force’s Pacific operations. Its existence is the result of collaboration by the Municipality of Anchorage, Doyon Utilities and JBER, and after just one year of successful operations is being expanded. The pieces to the project puzzle had been falling together for many years before it was a done deal. The first piece was passage of the Energy Policy Act of 2005, which required federal facilities to increase renewable energy consumption to at least 7.5 percent by 2013. In 2006, because it was exceeding the threshold limit for nonmethanogenic organic compound emissions, the Anchorage Regional Landfill brought on line a gas collection system, which it tested and operated for three years. During that time, Doyon Utilities purchased the utility infrastructure—electrical, water, sewer and natural gas distribution system— on three Army bases in Alaska: Ft. Wainright, Ft. Greely, and Ft. Richardson, which have merged into a joint base facility that is now run by the Air Force, says Robert Zacharski, JBER site manager. In 2010, the Municipality of Anchorage put out a request for proposals to use gas generated at ARL, and Doyon Utilities was selected. A contract was signed in 2011, and the power plant became fully operational just over one year later.

System Details The landfill gas collection system draws from 87 acres of landfill and consists of 36 vertically drilled wells, 21 horizontal collector wells that range between 60 and 120 feet deep, and eight interconnections with the leachate system. “We purchase methane from the municipality of Anchorage,” Zacharski explains. “A vacuum is applied to the landfill—if we get too much we’ll flare off the excess—and we bring our portion through a mile-long [low-pressure] pipeline to the base’s generating building.”


EARLY EXPANSION: The JBER Landfill Gas Waste-to-Energy Plant consists of four generator units designed to run on methane gas sourced from the Anchorage Landfill. A fifth is currently being installed, several years earlier than expected.

There, five 1.4 MW GE Jebaucher gas engines produce power that is tied into the base’s distribution system, enough electricity to meet half of the power demand for the Ft. Richardson side of JBER, or 100 percent of its emergency backup power.

The facility is currently undergoing an expansion—which was part of the initial plan—but it’s happening much earlier than expected, as there are few landfills of this size operating in similar climates to use as baselines for methane generation. “Initially











With an operation and maintenance budget of $639,000 for the power plant, gas processing facility and transmission pipeline, Doyon Utilities uses subcontractors as well as in-house personnel. The system is run by one operator, 40 hours a week, who can monitor it remotely to check for abnormalities, according to Zacharski. Surprisingly, operational challenges caused by the harsh climate have been minimal. “The gas supply remains very consistent between winter and summer,” Zacharski says. “You might think digestion would slow down in winter, but we haven’t found that’s the case.” Initially there were some issues with the outer piping and freeze ups, but it was remedied this summer. “We had some teething problems, but it hasn’t been really different operating a similar plant [elsewhere],” Zacharski says. One specific climate-driven innovation that the project partners believe is the only application of its kind and will reduce future maintenance and repair costs is installation of preinsulated HDPE (highdensity polyethylene pipe) with electric heat trace, to ensure the pipeline won’t become blocked with frozen condensate. In this case, the heat trace is a thin wire along the bottom of the pipe that can generate heat when needed. While the climate overall hasn’t been too different from developing a project in more temperate regions, doing so on a site owned by the military may pose more challenges than the typical model, according to Zacharski. “The Air Force has different


Operation, Maintenance and the Military

ideas of what an acceptable payback is, so you have to structure your finances to meet those expectations, and that may be difficult to do,” he says. “They want a pretty rapid turnaround.” Additionally, approval processes are lengthy. “Getting a notice to proceed to build a plant and making a schedule becomes challenging, when you don’t know when you’re going to get the go-ahead to start construction, or even if the project will go. On the private side of the fence, you have that control, but you lose a little of that on a military installation.” For the $35 million project, Zacharski said cash flow will turn positive in about four years. It is expected to result in a savings to JBER of $32 million in power costs


we put in four 1.4 MW generators, totaling 5.6 MW, and we’re just commissioning the fifth unit right now, which will put the plant at 7 MW. Our project financial model underestimated the gas generation in the landfill, so once we started operating it became apparent we could push up the fifth unit installation from year five to after year one.” A sixth unit is scheduled in five years, but Zacharski says gas use will be maxed out at that point.


over the initial contract period and $73.6 million over the potential life of the project, and the municipality will annually take in $1 million from gas sales, nearly $52 million over the life of the project. “In general, this has been a very successful project,” Zacharski adds. “It utilizes waste gas that was being flared, producing no value to anyone, to increase Doyon’s, the municipality’s and the Air Force’s bottom line.” Author: Anna Simet Managing Editor, Biomass Magazine 701-738-4961

Study highlights GHG reduction potential of butanol, drop-in biofuels U.K.-based Element Energy recently published a report finding that advanced biofuels offer a more cost-effective means to reduce greenhouse gas (GHG) emissions over the next 17 years, when compared to electric vehicles. The report, titled “The Role of Biofuels Beyond 2020,” was commissioned by BP. The U.K. has set targets calling for an 80 percent reduction in GHGs by 2050 when compared to a 2050 baseline. While electric plug-in and hydrogen vehicles are expected to play a significant role in realizing GHG reductions in the long term, the analysis

shows that the vehicle fleet will continue to be dominated by vehicles with internal combustion engines through at least 2030, which means biofuels will play an important role in meeting emissions goals. The analysis considers three scenarios. A “low biofuels” case in which conventional biofuels are blended at E10 and B7, a “medium biofuels” case assuming E20 and an increasing share of cellulosic ethanol, and a “high biofuels” case that considers the impact of blending butanol and drop-in biofuels at high rates.

NextFuels revives hydrothermal technology, plans test facilities

California-based NextFuels has unveiled its strategy to produce advanced biofuels from wet, unprocessed agricultural waste via a hydrothermal process originally developed by Shell in the 1980s. The company is currently focused on converting agricultural waste from palm oil production in Southeast Asia into


drop-in coal and petroleum replacements. The technology processes biomass within liquid water at temperatures of 300 to 330 degrees Celsius and pressure of 200 to 230 atmospheres, producing a putty-like GreenCrude. The GreenCrude can either be burned as a coal replacement, or further

refined into transportation fuels. NextFuels is in the process of designing and assembling a pilot plant in the Netherlands. The facility is expected to be operational by the second quarter of next year. The company also plans to construct a demonstration plant in Asia.


An Urgent Call to Action BY MICHAEL MCADAMS

I don’t cry wolf, but we are in the fight for the future of our industry. In mid-October, we saw a leaked draft of the proposed renewable fuel standard (RFS) 2014 Renewable Volume Obligation rule, which apparently would have favored the oil industry across the board. This draft proposal, which was cleverly leaked and circulated to the press, sought to color the attitude and direction of both the regulatory process as well as legislative discussions. All of this done at a time when the government is shut down and the press is solely focused on opening the government and avoiding a catastrophic default of paying our debts. Not to mention, most of the folks who would respond are at home on furlough. Our industry is currently staring down an effort to repeal the RFS by the oil industry and livestock agriculture, who are joined by several environmental organizations and the small engine manufacturers. We have endured multiple hearings on both sides of the Capitol and endless press briefing and articles assailing the RFS and the renewable fuels industry. Nevertheless, we are still standing and delivering more gallons of environmentally sustainable cheaper fuels every day. For over 40 years, the oil industry did not build a single refinery. They didn’t need to, because the big boys just kept making the refineries they owned larger and squeezing out the smaller refineries that competed against them. Today, to avoid their obligations under the RFS, refiners are exporting record volumes of gasoline. These exports specifically reduce their obligations under the act and save them cents on the gallon. Removing those gallons also reduces the size of the pool and reduces competition for price, thereby leaving consumers exposed to higher prices from the lack of volume and competition. And, refiners make more margins on their fewer gallons; this is 101 economics. And now we return to dysfunctional Washington, D.C. We have a government that has been shut down for two weeks with no agreement to open back up or increase the nation’s debt limit. There is no clear path for extending the biofuels tax credits—which all expire at the end of the year—and no Farm Bill

because we allowed the funding extension to expire at the end of September. And now, on top of these legislative issues, the renewable fuel sector also has to worry about just exactly what the U.S. EPA will do on the 2014 obligations. Under the RFS, the agency is required to release the next year’s volume obligations by Nov. 30 of each year. Because EPA did not finalize the 2013 numbers until August this year, most observers expect them to miss the deadline again, especially considering 96 percent of EPA employees are on furlough with no pay. On the good news front, EPA Administrator Gina McCarthy issued the following statement in response to extensive press coverage on the leaked 2014 RVO document: "The Obama Administration remains firmly committed to furthering the development of all biofuels—including corn-based ethanol, cellulosic biofuel, and advanced biofuel—as part of the president's commitment to developing a clean energy economy. Biofuels are a critical part of the president's all-of-the-above energy strategy that is reducing America's dependence on oil and creating jobs across the country. At this point, EPA is only developing a draft proposal. The agency has made no final decision on the proposed renewable fuel standards for 2014. “And no decisions will be made on the final standards without a full opportunity for all stakeholders to comment on the EPA's proposed 2014 renewable fuel standards and be heard on how to best foster a growing biofuels industry that takes into account infrastructure- and market-related factors." That means advocates for advanced biofuels still have an opportunity to stand up and fight to protect the RFS. The time is now and the need is for everyone to get involved. Contact your members of Congress, send comments to EPA, write a letter to your local newspaper or call me to talk about what you can do to help. The need is urgent and the wolf is lurking close by.

Isobutanol to the

Rescue The U.S. Coast Guard is testing isobutanol gasoline blends in its marine engines. BY CHRIS HANSON




ince its founding in 1790 as the U.S. Revenue Cutter Service, the U.S. Coast Guard has had a history of implementing new technology within its fleet. During the U.S. Civil War, for example, the USRC Naugatuck boasted twin-screw engines, ironclad armor and semisubmersible technology that allowed it to increase or decrease the ship’s draft in shallow waters. Continuing its pursuit of maritime innovation and reinforcing its motto of Semper Paratus (Always Ready), the USCG is conducting a year-long engine test using renewable, isobutanol-blended gasoline through a Cooperative Research and Development Agreement with Gevo Inc., Honda Motor Co. Ltd. and Mercury Marine. With a fleet of more than 2,000 cutter ships, boats and aircraft that conducted 19,790 search and rescues in 2012, cost-effective advanced biofuels that meet the USCG’s standards will help the organization break its reliance on foreign fuel sources and provide a stable fuel source in the event a conflict disrupts fuel supply lines.

Producing the Fuel


In 2011, the USCG began an alternative fuel study, motivated by the government’s desire to minimize its carbon footprint, says Michael Coleman, project manager for the U.S. Coast Guard Research and Development Center. From that initial study, the USCG

researched different alternative fuels for their affordability, availability, safety and potential carbon footprint reduction. The USCG selected four fuels: natural gas, ethanol blends, biobutanol and biomass liquid fuels. “Out of those four fuels, we did a desktop evaluation including many technical factors including maturity, performance, physical safety and logistics,” Coleman says. “Out of those, we decided to proceed with biobutanol as our test fuel.” For the engine tests, the USCG is sourcing the isobutanolblended fuel from Gevo’s plant in Luverne, Minn. The USCG selected a blend of 16.1 percent isobutanol and gasoline because of its potential benefits in an aquatic environment. “The Coast Guard, along with many other folks in the marine industry, is very interested in next-generation biofuels instead of ethanol-blended gasoline,” says Brett Lund, chief licensing officer for Gevo. He adds ethanol-blended gasoline is currently not compatible with most boat engines and its solubility with water make isobutanol a more attractive option. Gevo’s Luverne facility is a retrofitted ethanol plant that produces isobutanol using Gevo’s Integrated Fermentation Technology. Gevo is producing 8,700 gallons of blended isobutanol fuel at the facility for the Coast Guard tests. Producing the fuel presented some challenges that Gevo had

BOATING WITH ISOBUTANOL: The isobutanol blended fuels are being tested in a 25-foot response boat, left, and a 38-foot special purpose craft at its training center in Yorktown, Va.

to overcome, says Lund. Yeast naturally wants to produce ethanol, and small amounts of isobutanol. “We’ve spent quite a bit of time, five years or so, using metabolic engineering to develop a yeast that makes, almost exclusively, isobutanol,” he says. He notes isobutanol is toxic to the yeast and causes it to perish, therefore Gevo also had to develop a tolerant yeast strain. As the isobutanol is produced in the broth, Gevo extracts the isobutanol vapor under vacuum and condenses it into a liquid. “That really allows us to get the isobutanol out of the process without having to use conventional distillation to remove the water,” Lund explains.

Setting Sail After the initial alternative fuel study, the second phase of the isobutanol tests under the CRADA occurred over a three-month period in early 2013 using Honda outboard engines and craft, since Honda is one the major engine manufacturers for the USCG, Coleman says. In addition to material and benchmark testing, Honda also put the isobutanol blend through an endurance test prior to giving the USCG the approval of trying the fuel in its own boats, he explains. During Honda’s test, the engines operate at full throttle for eight hours a day over several months and then are taken apart and inspected. The next round of fuel tests are in progress at the U.S. Coast Guard Training Center in Yorktown, Va. “The training center is basically an area where Coast Guard members can learn how to operate the different boat platforms, be it anywhere from standard boat handling procedures to the mechanics of those craft,” says Lt. Kevin Sorrell. The center is a convenient location for testing due to its availability compared to other operational units, he adds.

At the Yorktown training center, the fuel is being tested on a 38-foot special-purpose craft using Mercury outboard engines as well as a 25-foot response boat (RBS) that uses Honda outboard engines. “Both crafts are operationally used in the Coast Guard,” says Sorrell. “RBSes are basically stationed all throughout the United States. The special purpose craft is more of a law enforcement craft, specifically used down in the southern U.S., like the Gulf of Mexico and Florida area.” “What we hope to accomplish with this project is to get the information that’ll give the Coast Guard decision makers the ability to make an informed decision on whether to proceed with butanol as an alternative fuel,” says Coleman. If the fuel tests turn out for the better, a positive testimonial from the USCG could be quite valuable for the advanced biofuel and boating industry. “This is really the option they are most excited about for their fleet and their industry. The fact that it’s all home-grown and the isobutanol is 100 percent produced in the U.S. is also beneficial,” says Lund. “They, as well as other branches of the military, like solutions like that because you avoid some of the risk of being cut-off from fuel supply.” “The nice part from our perspective is, if it’s good enough for the U.S. Coast Guard, it’s pretty much good enough for any marine application out there,” Lund adds. “Nobody runs their boats like these guys do.” Author: Chris Hanson Staff Writer, Biomass Magazine 701-738-4970
