The joint venture between California Bioenergy (CalBio), Chevron USA and local dairy farmers has announced the first renewable natural gas production from dairy farms in Kern County, California
Manure storage on dairy farms results in the release of methane and CalBio has constructed digesters and methane capture projects to convert this into RNG.
The project partners are providing funding for digester projects across three geographic clusters in Kern, Tulare and Kings counties.
The dairy biomethane projects will send dairy biogas to a centralised processing facility where it will be upgraded to RNG and injected into local utility SoCalGas’ pipeline. The RNG will be marketed as an alternative fuel, initially for heavy-duty trucks and buses.
