On June 10^th 2022, Aemetis hosted a Ribbon Cutting Ceremony for the Aemetis Biogas Central Dairy Digester Project at our Keyes Advanced Fuels Facility.

The event celebrated the commissioning of the company’s dairy renewable natural gas (RNG) cleanup and compression unit and interconnection with Pacific Gas & Electric’s (PG&E’s) gas pipeline, which is co-located at the facility. The full system enables the production and delivery of utility-grade RNG for sale as transportation fuel to customers throughout California via pipeline delivery.

When fully built out, the planned 60+ dairies in the Aemetis biogas project are expected to capture more than 1.6 million MMBtu of dairy methane annually and reduce greenhouse gas emissions equivalents by approximately 6.8 million metric tonnes of CO₂ in the next decade, equal to removing the emissions from approximately 1.1 million cars.

With well-established dairy relationships and as the state’s largest biofuels producer, it was a logical step for Aemetis to step forward as a developer of dairy biogas digesters to assist local dairy farmers meet the requirements of SB 1383 by capturing methane and converting it into a renewable, below zero carbon intensity biofuel (RNG) to replace petroleum fuel used in trucks across the state.
