Clean Energy Begins RNG Pipeline Injection from $85 Million Texas Facility

Clean Energy Fuels has started injecting renewable natural gas into the pipeline from its $85 million South Fork Dairy facility in Texas. The project, one of the nation’s largest RNG plants, processes 300,000 gallons of manure daily and will generate millions of gallons of low-carbon fuel each year.

(P&GJ) — Clean Energy Fuels Corp. has begun injecting renewable natural gas (RNG) into the interstate pipeline from its newly completed South Fork Dairy facility in Dimmitt, Texas—one of the largest RNG projects in the country.

The $85 million facility, financed entirely by Clean Energy, processes manure from a herd of 17,500 dairy cows to produce about 2.6 million gallons of RNG annually. It uses four anaerobic digesters and advanced gas conversion systems to process up to 300,000 gallons of manure per day, generating pipeline-quality gas for direct injection.

“The requirements to reach production and injecting milestones were extremely stringent and we are incredibly proud of the team for getting our seventh RNG facility online, on time and on budget,” said Clay Corbus, senior vice president at Clean Energy. “The completion of the project at South Fork is particularly special because not only is it a major step forward in building our low-carbon RNG supply to ensure we have the volumes needed to meet the growing fleet demand, but we were able to work side-by-side with such a remarkable dairyman in Frank Brand.”

“Partnering with Clean Energy to build an RNG facility on the dairy has been a success for us,” said Frank Brand, owner of South Fork Dairy. “We’re processing our manure into useful bedding and producing clean, useful fuel for vehicles – it’s pretty amazing stuff.”

Construction of the facility was briefly interrupted by a fire at the dairy, but both the farm and RNG operations have since been rebuilt and are fully operational.

The RNG produced at South Fork Dairy has received U.S. Environmental Protection Agency (EPA) approval to generate Renewable Identification Numbers (RINs) under the Renewable Fuel Standard (RFS) program. Clean Energy also expects to generate California Low Carbon Fuel Standard (LCFS) credits in early 2026.

Clean Energy operates more than 600 RNG fueling stations across the U.S. RNG derived from agricultural methane is one of the few fuels with a negative carbon-intensity score, lowering emissions both at the source and at the vehicle level while costing significantly less than diesel.
