In the United States (US), CalBioGas Hilmar LLC, a joint investment between Chevron U.S.A. Inc., a subsidiary of Chevron Corporation, and California Bioenergy LLC (CalBio), have announced that they have completed the central processing facility for their dairy biomethane project in Merced County, California (CA).
Methane is captured from a total of seven digesters that are part of the project. As part of the joint investment, after the methane is captured, it is sent to the central processing facility where it is upgraded into biomethane, aka renewable natural gas (RNG).
The RNG is then injected into the Pacific Gas and Electric Company (PG&E) pipeline where it is marketed as an alternative fuel for transportation.
We are proud of the progress we have made on these projects alongside our partner CalBio as we continue to provide lower carbon-intensity fuels to the California market. This partnership allows us to complement the strength of our traditional business to provide a broader suite of solutions to our customers, said Nuray Elci, VP of Renewables for Chevron.
Carbon-negative RNG
The RNG produced through this partnership is considered carbon-negative on a lifecycle basis under California’s Low Carbon Fuel Standard (LCFS).
Upon completion of the Hilmar RNG project, the estimated annual emissions reduction will be approximately 95,000 tonnes of carbon dioxide equivalents (CO2eq) per year according to the CA-GREET 3.0 Model.
Partnering with Chevron amplifies our commitment to creating lower carbon-intensity solutions for dairy farms by turning waste into renewable energy. By working together to reduce methane emissions from dairies, we’re not only helping the state achieve its methane reduction goals but also making a positive impact on our communities. This collaboration marks a step forward in the journey toward a lower carbon energy and dairy future. We are excited to support this effort to reduce methane emissions, said Ross Buckenham, CEO of CalBio.
The Hilmar RNG project was made possible through the support of several partners including 4Creeks Design, PG&E, and local dairy farmers.
Support was provided for the project through a California Department of Food and Agriculture (CDFA) grant, which was augmented with additional capital to complete the project.
PG&E is committed to achieving a clean, decarbonized net-zero energy system by 2040. We are proud to support the CalBioGas Hilmar LLC RNG facility and the interconnection, transport, and delivery of this renewable resource to realize this goal. We look forward to our continued collaboration with CalBio in the coming years to reduce greenhouse gas emissions by delivering clean, renewable energy here in Northern California, said Kevin Armato, VP of Transmission and Distribution Construction at PG&E.
