LOS ANGELES, February 14, 2019 – Southern California Gas Co. (SoCalGas) and biogas producer Calgren Dairy Fuels (Calgren) today announced that renewable natural gas produced at Calgren’s dairy digester facility in Pixley, California is being injected into SoCalGas pipelines. The project marks the first time that carbon-
negative renewable natural gas produced from cow manure has been injected directly into SoCalGas’ natural gas system. In August 2018, SoCalGas began receiving renewable natural gas into its system from CR&R, Inc.’s anaerobic digestion facility in Perris, California. The renewable natural gas from that digestion facility is already being used to fuel about 400 waste hauling trucks. Renewable natural gas is a carbon-negative fuel produced from waste and agriculture that can be used in trucks and buses, to generate electricity, fuel heating systems in homes and businesses, and for cooking.
“Developing renewable natural gas is a smart and cost-effective solution to reducing greenhouse gas emissions from the transportation and building sectors,” said Sharon Tomkins SoCalGas vice president for customer solutions and strategy. “Replacing just 16 to 20 percent of our traditional natural gas with renewable natural gas would reduce emissions equal to electrifying 100 percent of buildings in the state, but it would be two to three times more cost-effective. Moreover, the renewable natural gas solution does not require expensive appliance change outs or costly new mandates.”
