Clean Energy Fuels sells $30.7m in federal tax credits from RNG projects

Clean Energy Fuels Corp., a renewable natural gas (RNG) producer with operations spanning Texas, Minnesota, Iowa, and South Dakota, has completed the sale of $30.7 million in federal tax credits tied to its seven operational RNG facilities. The deal highlights the company’s fourth such transaction, with the bulk of proceeds coming from the $26 million investment tax credit (ITC) generated by its South Fork Dairy facility in Dimmit, Texas, which began producing RNG in 2025. The sale also includes 2025 Section 45Z clean fuel production credits from the same seven facilities, which collectively generated 2.7 million gallons of negative-carbon-intensity RNG for transportation use in that year. Will Flanagan, vice president of strategic development at Clean Energy Fuels, described the transaction as the company’s largest ITC sale to date, emphasizing its contribution to the RNG business’s financial performance.
