Furthermore, Aemetis Biogas has filed to generate California Low Carbon Fuel Standard (LCFS) credits for renewable natural gas (RNG) that was delivered to heavy transportation customers starting in late May 2023.
D3 Cellulosic RINs are the most valuable type of federal renewable fuels credit and the LCFS Temporary Pathway filing enables Aemetis Biogas to sell RNG to trucking companies to displace petroleum diesel. Aemetis Biogas has already built and now is operating 40 miles of biogas pipeline, a central biogas-to-RNG production facility, a PG&E utility gas pipeline interconnection, and seven dairy digesters that are producing biogas, stated Andy Foster, President of Aemetis Biogas.
The Aemetis Biogas project is managed by a recently installed Allen Bradley Decision Control System (DCS) with Artificial Intelligence (AI) energy and process management capabilities.
The integrated, on-site, and remote management of the Aemetis Biogas network of dairy digesters supports the rapid addition of dairy digesters to the 40-mile Aemetis pipeline and Biogas-to-RNG system with utility interconnect.
We have five dairy digesters under construction and an additional 25 digesters in various stages of development. Generating valuable D3 RINs and filing for LCFS Temporary Pathway credit revenues are the two most important revenue milestones for the dairy RNG project since we started engineering and permitting work in 2018, allowing us to expect positive cash flow from biogas beginning in the third quarter of this year, said Eric McAfee, Chairman and CEO of Aemetis.
The Aemetis Biogas network of dairy digesters in Stanislaus and Merced Counties of California, and the AI Decision Control System, is partially funded by more than US$25 million of grants awarded by the California Department of Food and Agriculture (CDFA), California Energy Commission (CEC), and the Pacific Gas and Electric Co. (PG&E) utility.
Aemetis Biogas has received loan guarantee commitments for 20-year project development loans from the US Department of Agriculture (USDA) under the Renewable Energy for America Program (REAP).
Four loans for a total of US$100 million of additional USDA REAP funding are in process to fund the next phases of a total of 60 dairy digesters scheduled to be built in the next sixty months.
