Calgren Opens First Dairy RNG Facility in California

Southern California Gas Co. (SoCalGas) joined Calgren Dairy Fuels, and state and local elected officials yesterday to announce the completion of Calgren’s dairy renewable natural gas facility.

 The project, located in the Central Valley community of Pixley, is the first of its kind in California and is expected to be the largest dairy biogas operation in the U.S. later this year. At the new facility, Calgren collects cow manure – a potent source of greenhouse gas emissions – from four local dairy farms and processes it in an anerobic digestor that accelerates the natural decomposition process. Methane emissions (biogas) from that process are captured and converted to make renewable vehicle fuels. Producing pipeline quality renewable natural gas (RNG) that is then injected into the SoCalGas pipeline system which allows Calgren to supply RNG to existing compressed natural gas (CNG) refueling facilities. Ultimately, this also has the potential to be delivered to customers to fuel ultra-low emissions trucks and buses, generate clean electricity, and heat homes and businesses.
