Aemetis Biogas receives CARB approval for seven RNG pathways
In the United States (US), Aemetis, Inc., a renewable natural gas and renewable fuels company, has announced that the California Air Resources Board (CARB) has approved provisional pathways under the Low Carbon Fuel Standard (LCFS) for seven dairy digesters built and operated by its subsidiary Aemetis Biogas Inc.
According to a statement, the pathway approvals are effective as of January 1, 2025. The average carbon intensity (CI) for the seven approved pathways is -384, with carbon intensities ranging from -327 to -419.
The approval of seven LCFS pathways increases the number of LCFS credits generated by these digesters by approximately 100 percent. With eleven operating digesters and a four-dairy cluster digester currently being completed, we have additional pathway filings in process that we expect will be approved more quickly than these initial pathways once the LCFS regulatory amendments are adopted this year, stated Eric McAfee, Chairman and CEO of Aemetis.
With the LCFS first quarter reporting deadline of June 30, 2025, the January 1, 2025, effective date of the new pathways enables Aemetis to immediately obtain the increased LCFS credit quantity for its RNG produced in the first quarter of 2025.
Aemetis renewable energy and energy efficiency projects include the construction of new dairy digesters expected to generate more than 1 million MMBtu per year of RNG; the Keyes ethanol plant mechanical vapor recompression system that is expected to generate US$32 million of increased annual cash flow starting in 2026; the Riverbank carbon sequestration project to inject 1.4 million tonnes per annum of carbon dioxide (CO2) per underground; and the 78 million (US) gallon (≈ 295.2 million litres) per year sustainable aviation fuel (SAF) and renewable diesel plant that has already received Authority To Construct air permits and other key approvals.
