The joint venture created by California Bioenergy LLC (CalBio), Chevron U.S.A. Inc. and local dairy farmers – CalBioGas LLC – has successfully achieved its first renewable natural gas (RNG) production from dairy farms in Kern County, California.

The partners said the milestone underpins their commitment to provide affordable, reliable, and ever-cleaner energy to California consumers.

Manure storage on dairy farms results in the release of methane, a greenhouse gas. CalBio, a developer of dairy digesters for generating renewable electricity and vehicle fuel in California, helps build digesters and methane capture projects to convert this methane to a beneficial use as RNG.

CalBio, dairy farmers and Chevron are providing funding for digester projects across three geographic clusters in Kern, Tulare and Kings counties. As they are completed, these projects will mitigate the dairies’ methane emissions and reduce greenhouse emissions from livestock.

The dairy biomethane projects are designed to send dairy biogas to a centralized processing facility where it will be upgraded to RNG and injected into local utility SoCalGas’ pipeline. The RNG is then marketed as an alternative fuel for heavy-duty trucks and buses.

“The project is the result of efforts of a remarkable range of stakeholders, including the California Department of Food and Agriculture, the California Energy Commission and the California Public Utility Commission. CalBio also is honored to be supported by a group of California’s dairy farmers, Farm Credit West and Chevron, California’s largest energy company,”​ said N. Ross Buckenham, CalBio’s CEO.

“These projects bring so many win-wins – they help create local jobs, improve local air quality by producing renewable natural gas for use in low-NOX emission fleets, and reduce dairy methane emissions.”

Andy Walz, president of Chevron Americas Products, said, “This is an exciting milestone that speaks to the capabilities and can-do attitude of our partners – CalBio and dairy farmers – to bring this RNG to the California vehicle fuels market.

“Chevron is increasing RNG in support of our business and is making targeted investments and establishing partnerships, as we evaluate many emerging sources of energy and the role they will play in our portfolio. And as a proud California company, we are pleased that local communities in the state will benefit from this investment.”
