Ethanol Producer Magazine – The latest news and data on ethanol production


Aemetis Inc., a renewable natural gas (RNG) and renewable fuels company focused on carbon-negative products, announced that its subsidiary Aemetis Biogas LLC has signed the Standard Renewable Gas Interconnection Agreement (SRGIA) with Pacific Gas & Electric Company and funded the final payment of $ 1.2 million for the installation of PG&E interconnection equipment to bring renewable natural gas (RNG) through the utility pipeline in the fourth quarter of 2021.

The PG&E RNG interconnect equipment has already been manufactured on modular units which are now due to be delivered to the Keyes plant and installed within the next three months. When the interconnect unit is complete, the RNG produced by the Aemetis Biogas Central Diary Digester project will be delivered to the Pacific Gas & Electric natural gas pipeline for sale to customers throughout California as transportation fuel.

“As planned, the engineering, permits, off-site equipment fabrication and full payment of $ 2.3 million to PG&E have been completed,” said Andy Foster, president of Aemetis Biogas subsidiary of Aemetis , Inc. “PG&E manages the manufacture and installation of the interconnection system connecting the Aemetis biogas purification and compression facility to the pipeline. We are delighted that an important milestone for the completion of the Aemetis Biogas Central Dairy project has been taken today. “

Aemetis has already built and currently operates two dairy biogas digesters, on-site dairy gas upgrading and pressurization facilities, and a four-mile biogas pipeline connecting the dairies to the Aemetis Keyes ethanol plant. Centralized biogas cleaning and on-site RNG refueling facilities at the Keyes plant are currently under construction for completion in Q4 2021, and construction of 15 additional dairy biogas digesters is underway to be completed in 2022 .

The PG&E interconnection unit is a gateway for the lagoon digesters network being built by Aemetis Biogas to produce renewable natural gas (RNG) for use as transport fuel. The biogas produced by the first two dairy digesters received a California Air Resources Board (CARB) approved route using a negative carbon intensity (CI) of 426 (-426) and is currently being used to replace natural gas based on Keyes ethanol consumed petroleum. process energy production facility.

When fully constructed, the 52 dairies planned for the Aemetis biogas project are expected to capture more than 1.4 million MMBtu of dairy methane and reduce greenhouse gas emissions equivalent to approximately 5.2 million metric tonnes of CO.2 each year, which is equivalent to eliminating the emissions of about 1.1 million cars per year.

The Aemetis Biogas Dairy RNG Project, Aemetis Keyes Biofuel Plant Energy Efficiency Improvements, and the Aemetis Renewable Jet / Diesel Project include $ 57 million in grants and other support from the US Department of Agriculture , US Forest Service, California Energy Commission, California Department of Food and Agriculture, CAEATFA, and Pacific Gas and Electric’s Energy Efficiency Program.
