Clean Energy’s Latest RNG Production Facility at Minnesota Dairy Begins Injecting Into Pipeline

Clean Energy Fuels Corp. (Nasdaq: CLNE) announced that it has completed its latest renewable natural gas (RNG) production facility at Ash Grove Dairy in Lake Benton, MN. Now producing pipeline quality RNG and injecting it into the interstate natural gas pipeline grid, the facility is projected to supply up to 480,000 gasoline gallon equivalent (GGEs) of negative carbon-intensity RNG annually when at full capacity and will provide Clean Energy’s stations with clean-burning fuel for its commercial transportation fleet customers.

Located on a 55-acre site, Ash Grove Dairy is a multigenerational dairy farm home to more than 2,000 milking cows which produce milk, cheese, yoghurt and now clean RNG. The freestanding one-digester facility will process up to 60,000 gallons of manure each day, capture its harmful methane and prevent it from entering the atmosphere. This biogas will be converted into an estimated 165 MMBtus of RNG every day.

The project, financed through one of Clean Energy’s production joint ventures and developed by Dynamic Renewables, totaled $22 million and has now passed necessary gas testing and is officially producing ready-to-use RNG. Clean Energy is in the process of filing the applications to generate 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. “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.”

Agriculture accounts for nearly 10 percent of U.S. GHG emissions and the transportation sector accounts for another 28%, according to the U.S. Environmental Protection Agency. Capturing methane from farm waste lowers these emissions. RNG, produced by that captured methane and used as a transportation fuel, significantly lowers GHG emissions on a lifecycle basis when compared to diesel. This allows RNG to be one of the only fuels to receive a negative carbon-intensity score based on the reduction of emissions at the source and at the vehicle.

About Clean Energy

Clean Energy Fuels Corp. is the country’s largest provider of the cleanest fuel for the transportation market. Our mission is to decarbonize transportation through the development and delivery of renewable natural gas (RNG), a sustainable fuel derived by capturing methane from organic waste. Clean Energy allows thousands of vehicles, from airport shuttles to city buses to waste and heavy-duty trucks, to reduce their amount of climate-harming greenhouse gas. We operate a vast network of fueling stations across the U.S. and Canada as well as RNG production facilities at dairy farms.
