Calgren Dairy Fuels injects bio-RNG into Southern California Gas pipelines

In California, Southern California Gas Co. and biogas producer Calgren Dairy Fuels announced Feb. 14 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.
