Clean Energy Fuels launches new RNG facility at Minnesota dairy

In Minnesota, Clean Energy Fuels announced the completion of its latest production facility at Ash Grove Dairy in Lake Benton, Minnesota where biogas is converted into approximately 165 MMBtus of renewable natural gas each day. The new facility injects RNG into the interstate natural gas pipeline grid, and is expected to produce up to 480,000 gasoline gallon equivalents of negative carbon-intensity RNG annually when at full capacity.

Located on a 55-acre site, Ash Grove Dairy houses over 2,000 milking cows and processes up to 60,000 gallons of manure daily through the anaerobic digester.

The $22 million project was financed through one of Clean Energy’s joint ventures and developed by Dynamic Renewables. It has passed all necessary gas testing and is officially operational, with applications underway for federal and state environmental credits.

“Ash Grove is our fifth renewable natural gas facility to come online in the last nine months,” said Clay Corbus, senior vice president at Clean Energy. “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.”
