Aemetis, Inc. announces that its subsidiary Aemetis Biogas has completed an additional seven miles of underground 聽pipeline to transport biogas from five new dairy digesters to the centralized Renewable Natural Gas upgrading facility located at the Aemetis Keyes biofuels plant.聽 Including the four miles of biogas pipeline commissioned in late 2020, Aemetis has now installed more than 11 miles of pipeline and is on track to complete the 36-mile biogas pipeline network in 2022.
Construction crews are now working on an additional 25 miles of pipeline spanning Stanislaus and Merced Counties to transport biogas for Phases 2 and 3 of the project.聽 The Aemetis biogas pipeline project, 52 diary digesters, central biogas upgrading, and PG&E gas pipeline interconnect facilities will bring an estimated $300 million of new capital investment to California鈥檚 Central Valley, while generating additional revenues and new jobs for a wide variety of businesses in agricultural communities.
鈥淲ith five dairy biogas digesters under construction and scheduled to begin biogas production by mid-year, the completion of this phase of pipeline on time and under budget is another significant milestone for the Aemetis Biogas dairy RNG project,鈥� said Andy Foster, President of Aemetis Biogas. 聽鈥淏y year鈥檚 end, we expect to have built 15 new dairy digesters and completed the 36-mile biogas pipeline network, providing immediate benefits to the region鈥檚 air quality and the state鈥檚 low carbon transportation fuel supply.鈥�
In support of California鈥檚 numerous climate change initiatives to reduce greenhouse gas emissions (GHG) and provide negative carbon intensity (CI) transportation fuels, Aemetis plans to increase its renewable natural gas production to more than 1.4 million MMBtu鈥檚 per year of negative carbon intensity transportation fuel, sourced from 52 dairy digesters located in the state鈥檚 San Joaquin Valley, a region cited by the US EPA as having some of the nation鈥檚 worst air quality.聽 The Aemetis Biogas dairy RNG project is designed to reduce GHG emissions by an estimated 5.2 million metric tonnes of CO2 each year, equal to removing the emissions from 1.1 million cars from California roads each year.
The Aemetis Biogas dairy RNG project, energy efficiency upgrades to the Aemetis Keyes biofuels plant, and the Aemetis Renewable Jet/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, and Pacific Gas and Electric鈥檚 energy efficiency program.
