Renewable Natural Gas MEASUREMENT SOLUTIONS
Renewable Natural Gas
Methane-Rich Biogas
Renewable Natural Gas (RNG), also known as biomethane, is a sustainable fuel that has been upgraded to meet natural gas pipeline quality standards.
RNG is produced through the processing of organic waste materials, such as food waste, animal excrement, and sewage.
The organic waste undergoes anaerobic digestion (a biological process where bacteria break down the biodegradable material in the absence of oxygen). This process produces biogas, which is a mixture primarily composed of methane and carbon dioxide.
The biogas is then processed and upgraded by removing impurities like moisture, hydrogen sulfide, and carbon dioxide. This purification process results in a renewable fuel source that has a very high methane content, similar in quality and properties to conventional natural gas.
RNG can be used for many of the same applications as conventional natural gas, such as heating, electricity generation, and transportation fuel. It is considered a renewable and low-carbon energy source that can help diversify energy supplies and reduce reliance on fossil fuels.
Renewable Natural Gas
Organic Waste to RNG
Using Renewable Natural Gas contributes to the reduction of greenhouse gas emissions and the transition towards a more sustainable and circular economy by using organic waste as a valuable energy resource.
Four industries primed to produce RNG:
• Landfills (LFG)
• Organic Waste
• Water Wastewater
• Livestock Waste
Raw biogas is mainly methane and carbon dioxide with traces of other elements such as water, hydrogen sulfide, siloxanes, nitrogen, and oxygen.
Waste products, such as sludge, food waste or manure are processed in a biodigester.
The biodigester breaks down the organic material to create biogas a mixture of methane and other elements.
The biogas can then be processed and conditioned leaving behind RNG, which can be used interchangeably with traditional natural gas.
This RNG can be used where it is produced for things like generating electricity or fueling vehicles, or it can be injected into a utility pipeline for transportation to other customers.
Reduced greenhouse gas emissions compared to fossil natural gas

Renewable Natural Gas
Federal Renewable Fuel Standard Program
Facilities are now required by law to continuously measure flow and gas quality with a gas chromatograph (GC) for raw biogas and finished RNG.
Many RNG producers do not meet the new ruling and will need GCs on raw biogas streams. This also applies to different flow measurement applications.
EXISTING
FUEL PATHWAYS NEED TO BE AMENDED BY JANUARY 1, 2025 to comply with the new RFS rule.
NEW PATHWAYS REGISTERED AFTER JULY 1, 2024 MUST COMPLY IMMEDIATELY.
CONTINUOUS MEASUREMENT means the automated measurement of specified parameters of biogas, treated biogas, or natural gas recorded according to the following frequencies:
In-line Gas
Chromatograph (GC)
Automated measurement recorded at least every 15 minutes
Flow Meter
Automated measurement every 6 seconds, with weighted totals recorded at least every minute
MEASUREMENT STANDARDS
Other meters
Automated measurement occurring at a frequency specified at registration
The EPA requires specific standards that must be used when measuring biogas properties, as stated in § 80.155 and shown in the chart below:

Renewable Natural Gas
Renewable Identification Numbers (RINs)
The Renewable Fuel Standard (RFS) program, administered by the Environmental Protection Agency (EPA), requires a certain volume of renewable fuels be blended into the nation's transportation fuel supply each year.
Renewable Identification Numbers (RINs) are tradable credits used for compliance with the RFS program in the USA.
To demonstrate compliance, refiners and importers of gasoline and diesel must accumulate and surrender a certain number of RINs every year.
STEP 1
STEP 2
Each batch of renewable fuel produced or imported receives a unique 38-character RIN assigned by the EPA.
STEP 3
When the renewable fuel is blended with gasoline or diesel, the RIN can be separated and used for compliance or traded.
STEP 4
Obligated parties (refiners, importers) must accumulate sufficient RINs to meet their share of the year's blending requirements.
RINs can be traded on an open market, allowing obligated parties to buy RINs from others if they don't have enough from blending activities.
STEP 5
At the end of each year, obligated parties must retire the required number of RINs with the EPA to demonstrate compliance.

Maximize Your RNG
Update Your Engine Control Systems to Better Burn the Biogas Produced
Winn-Marion offers industry leading Woodward gas engine and dual fuel control solutions. Producing BTUs costs money to capture, compress, or flare. Convert the excess into valuable power to increase your bottom line.
Woodward’s engine control unit (ECU) is designed with high-speed, on-engine processor and control algorithms to assess pressure for each cylinder, each cycle, and convert the information into metrics such as center of combustion, rate of pressure rise, and peak pressure. With this data, the ECU can control combustion phasing in reactivity-controlled compression ignition (RCCI) combustion. Additionally, the combustion metric feedback can be used to maintain good combustion phasing during changes in substitution rates and when the fuel quality changes.
