Aemetis, Inc. is an enterprise specializing in renewable natural gas and sustainable fuels, conducting operations across North America and India. The company's business activities are structured into three primary divisions: California Ethanol, Dairy Renewable Natural Gas, and India Biodiesel. A core objective for Aemetis is the procurement, development, and market launch of innovative products and technologies that offer negative carbon intensity, serving as eco-friendly alternatives to traditional petroleum-based goods. Its biodiesel products are distributed to a diverse range of customers, including government oil marketing agencies, transportation companies, various resellers, distributors, and private refiners. These sales are facilitated through both its in-house sales team and independent sales agents, as well as via brokers who then supply end-users. Beyond biodiesel, the company also produces and markets ethanol. Furthermore, Aemetis creates and supplies valuable co-products for animal feed, such as wet distillers grains, distillers corn oil, and condensed distillers solubles, to dairies and feedlots. The company's offerings also encompass the generation of dairy biogas, the production and sale of high-grade alcohol, various feed products, and hand sanitizers. Aemetis actively invests in research and development, particularly focusing on advanced conversion technologies that transform waste feedstocks into biofuels and biochemicals. Founded in 2005, the company initially operated as AE Biofuels, Inc. before officially adopting the name Aemetis, Inc. in November 2011. Its corporate headquarters are located in Cupertino, California.
Aemetis Receives $22.4 million from Sale of Section 45Z Clean Fuel Production Tax Credits
Aemetis received $22.4 million from the sale of Section 45Z Clean Fuel Production Tax Credits generated from its 2026 ethanol and renewable natural gas production.
The credits were valued at roughly $0.33 per gallon of ethanol and $62 per MMBtu of RNG before sale discounts, based on the DOE's updated 45ZCF-GREET model issued September 8, 2026.
The updated model adds pathways for dairy-manure RNG and low-carbon regenerative corn, and management expects the value of 45Z credits to grow as production volumes and energy-efficiency projects expand.
