In the United States (US), Aemetis, Inc., a renewable natural gas and renewable fuels company, has announced that its Aemetis Biogas LLC subsidiary received funds from the sale of US$17 million of federal clean energy tax credits, including a Section 45Z Clean Fuel Production Tax Credit (PTC) and a Section 48 Investment Tax Credit (ITC).
The Federal Clean Energy Tax Credit transaction included approximately US$12 million for a Section 48 ITC generated from the construction of a dairy manure digester that produces biogas and approximately US$5 million from a Section 45Z PTC generated from renewable natural gas (RNG) production during 2025.
Net cash proceeds from the transaction were approximately US$15 million after transaction costs.
This tax credit sale represents an important step in monetizing federal clean fuel transferable tax incentives and establishing a new recurring source of cash flow. This is our first sale of a Section 45Z Clean Fuel Production Credit from dairy RNG, and we expect additional Section 45Z transactions in 2026 and future years from ongoing renewable natural gas production, along with additional Section 48 transactions from ongoing digester construction, said Eric McAfee, Chairman and CEO of Aemetis.
The Section 45Z Clean Fuel Production Credit sold in this transaction was calculated under current Treasury guidance.
The Company expects the amount of future 45Z tax credits to increase significantly based on production volume increases, increased credit values mandated by the One Big Beautiful Bill Act, and expected additional regulatory clarity.
In addition, Aemetis expects to generate a transferable Section 45C tax credit in 2026 worth US$10.5 million, which has received approval from the Internal Revenue Service (IRS) and the Department of Energy (DOE)
With the completion of US$95 million of ITC transactions and today’s first Section 45Z sale, we are executing our tax credit monetization strategy. We expect federal 45Z Clean Fuel Production Credits to be a rapidly growing source of operating cash flow to support the expansion of production and new job creation, ended Eric McAfee.
