Clean Energy Breaks Ground on RNG Dairy Digester

Clean Energy Fuels Corp. has announced it has broken ground on a renewable natural gas (RNG) digester at Del Rio Dairy in Friona, Texas - its first in a joint venture with TotalEnergies to produce ultra-clean transportation fuel which will be negative carbon intensive. All the RNG fuel produced at Del Rio Dairy will make its way into Clean Energy’s nationwide network of RNG stations.

When completed, the Del Rio Dairy digester project will capture the waste from more than 7,500 milking cows and generate an anticipated 1.1 million gallons of RNG annually. RNG helps Clean Energy’s customers achieve their sustainability goals by dramatically reducing their greenhouse gas (GHG) emissions from transportation operations. Clean Energy has a target to provide RNG at all its U.S. stations and for the carbon intensity (CI) of the fuel to be zero by 2025.  

On Nov. 17, Andrew J. Littlefair, president and CEO of Clean Energy, participated in a groundbreaking ceremony with members of the Gingg family who own Del Rio Dairy and executives from TotalEnergies, Montrose Environmental Group, a provider of environmental solutions, providing EPC, startup, and commissioning services for the project. Other partner companies include Black Bear Environmental Asset Advisors, a research and consulting firm, and Atmos Energy, a distributor of natural gas.

Agriculture accounts for nearly 10% of U.S. GHG emissions, according to the U.S. Environmental Protection Agency. Capturing methane from farm waste can lower these emissions. RNG is used as a transportation fuel and has lower GHG emissions on lifecycle basis when compared to conventional gasoline and diesel. The California Air Resources Board has given similar projects a carbon intensity (CI) score of weighted average of -320 compared to CI scores of 101 for conventional diesel fuel and 15 for electric batteries.
