Vendor Selected Based on Proven Track Record of Quality Work on Previous Aemetis Projects and Extensive Utility Pipeline Construction Experience

CUPERTINO, CA - (NewMediaWire) - August 13, 2021 - Aemetis, Inc. (NASDAQ: AMTX), a renewable natural gas (RNG) and renewable fuels company focused on negative carbon intensity products, announced today that it has awarded a construction services contract to Machado & Sons Construction Inc. (“Machado & Sons”) to build the Company’s 32-mile biogas pipeline extension connecting multiple dairy digesters throughout Stanislaus and Merced Counties in California. The pipeline will transport the renewable biogas from the dairies to the Aemetis biogas upgrading facility at the Aemetis ethanol production plant in Keyes, California, where the biogas will be transformed into commercial-grade RNG for use as a carbon-negative transportation fuel for trucks, buses and cars. 

After a procurement process that included proposals from ten pipeline construction companies, Aemetis selected Machado & Sons due to their extensive experience in utility-grade pipeline construction, as well as their successful completion of a separate CO2 pipeline from the Aemetis ethanol production facility in Keyes to the CO2 liquification gas plant built in 2019. Machado and Sons is also currently engaged as a key construction contractor for the Aemetis biogas upgrading facility.

“Through a competitive bidding process with a number of highly qualified pipeline contractors, Aemetis is very pleased to select Machado & Sons for the second stage of the dairy biogas pipeline construction,” said Andy Foster, President of Aemetis Biogas. “Over the past few years, we have completed a number of projects with Machado & Sons, and continue to be impressed with their collaborative attitude, outstanding safety record, and exceptional construction capabilities.”

“We conducted extensive value engineering outside of the regular bid process to demonstrate our ability to execute this project safely, on time, and within budget,” said Mike Machado, President of Machado & Sons. “We have completed multiple projects with Aemetis and appreciate their professionalism during project development. We are pleased to be a key contractor in building projects that fulfill the Aemetis mission to produce carbon-negative transportation fuels.”

The pipeline is part of the Aemetis Biogas Central Dairy Digester Project which is developing a network of lagoon digesters connected via a biogas pipeline to produce renewable natural gas (RNG).  The RNG produced by the first two dairy digesters has been approved by the California Air Resources Board (CARB) at a negative 426 (-426) carbon intensity to displace petroleum based natural gas used at the Keyes ethanol production facility, and to provide carbon negative renewable fuel for compressed natural gas trucks and buses.

Phase 1 of the Aemetis Biogas project was completed in September 2020, including two dairy lagoon digesters and four miles of pipeline connected to the Aemetis Keyes ethanol plant to reduce the carbon intensity of ethanol produced by the Keyes plant.  

The planned 52 dairies in the Aemetis biogas project are expected to capture more than 1.4 million MMBtu of dairy methane and reduce greenhouse gas emissions equivalent to an estimated 5.2 million metric tonnes of CO2 each year. The captured methane will be transformed to carbon-negative transportation fuel to displace petroleum-based diesel throughout the State of California. 

The 5.2 million metric tonnes of annual CO2 emissions reduction from the Aemetis Biogas project is estimated to reduce CO2 emissions equivalent to removing 1.1 million cars from the road.  

The Aemetis Biogas dairy RNG project, energy efficiency upgrades to the Aemetis Keyes biofuels plant, and the Aemetis Renewable Jet/Diesel project include $57 million of grant funding and other support from the US Department of Agriculture, the US Forest Service, the California Energy Commission, the California Department of Food and Agriculture, the California State Treasurer’s Office, and Pacific Gas and Electric’s energy efficiency program.
