California-based Clean Energy Fuels has started producing renewable natural gas (RNG) from its facility in Minnesota, the company said Aug. 5, transforming cow manure into pipeline quality gas.

Located at the Ash Grove Dairy in Lake Benton, the facility is expected to supply up to 480,000 gasoline gallon equivalent of negative carbon-intensity RNG annually when at full capacity, according to a news release. The facility will process up to 60,000 gallons of manure daily, capturing methane and converting it into 165,000 MMbtus of RNG daily.

The $22 million project was financed through one of Clean Energy’s production joint ventures and developed by Dynamic Renewables. The dairy farm is home to more than 2,000 milking cows, according to the news release.

Ash Grove is Clean Energy’s fifth renewable natural gas facility to come online in the last nine months.

“It’s always rewarding to see our efforts come to fruition when we begin injecting. With the growing demand for RNG, and interest really starting to take off as fleets realize how effective and immediate they can fuel cleanly, the RNG produced at Ash Grove will directly help with reducing carbon emissions across the country,” said Clay Corbus, senior vice president at Clean Energy.
