CalBioGas Hilmar LLC, a joint investment between Chevron and California Bioenergy LLC, has completed the central processing facility for its dairy biomethane project in Merced County, California. After the methane is captured, it is sent to the central processing facility where it is upgraded into renewable natural gas (RNG). The RNG is then injected into the Pacific Gas and Electric Company pipeline where it is marketed as an alternative fuel for transportation.
The RNG produced through this partnership is considered carbon negative on a lifecycle basis under California’s Low Carbon Fuel Standard. Upon completion of the project, the estimated annual emissions reduction will be approximately 95,000 MT of carbon dioxide equivalent per year, according to the CA-GREET 3.0 Model. This methane is captured from a total of seven digesters that are part of the project.
