Aemetis gets Environmental OK for 24-mile biogas pipeline extension at Keyes complex

November 29, 2023 |

In California, the Stanislaus County Board of Supervisors, upon a 4 to 0 vote, approved the California Environmental Quality Act analysis for Aemetis Biogas LLC to extend its biogas pipeline by an additional 24 miles using the public right of way. The pipeline transports biogas from dairy digesters to a centralized renewable natural gas upgrading facility located at the Aemetis Keyes biofuels plant. The pipeline extension will enable Aemetis to add 21 additional dairies to the Aemetis Biogas project in Stanislaus and Merced Counties.  Aemetis has already installed 36 miles of biogas pipeline, and with the additional 24 miles of pipeline, the company has CEQA approval for a total of 60 miles of public right of way for a biogas gathering pipeline that will collect biogas from an aggregate of 38 dairies.

The Aemetis Biogas pipeline project, including dairy digesters, collection pipeline, centralized biogas upgrading facility, RNG fueling station, and PG&E gas pipeline interconnection, is investing more than $300 million in California’s Central Valley.

The Aemetis Biogas dairy RNG project, energy efficiency upgrades to the Aemetis Keyes biofuels plant, and the Aemetis Sustainable Aviation Fuel and Renewable Diesel project include $57 million of grant funding and other support from the California Air Resources Board, the US Department of Agriculture, the US Forest Service, the California Energy Commission, the California Department of Food and Agriculture, CAEATFA, the San Joaquin Valley Air Pollution Control District, and Pacific Gas and Electric’s energy efficiency program.
