Clean Energy Fuels Corp. is leveraging federal tax incentives to accelerate capital liquidity within its renewable natural gas (RNG) segment. The company recently completed a $30.7 million sale of federal tax credits derived from seven of its RNG production facilities. This transaction marks the fourth time the company has successfully monetized credits from its existing RNG project portfolio.
South Fork Dairy Drives $26M ITC Sale
The transaction is heavily anchored by a $26 million investment tax credit (ITC) linked to the South Fork Dairy facility located in Dimmit, Texas. This specific project, which began producing RNG in 2025, represents the largest ITC sale in the company's history to date. Beyond this single asset, the deal encompasses all 2025 Section 45Z clean fuel production credits generated across a broader portfolio of dairy-based RNG projects. These assets are distributed across Texas, South Dakota, Iowa, and Minnesota, including specific projects managed through Clean Energy’s joint ventures with energy majors bp and TotalEnergies.
Portfolio Carbon Intensity and Production Scale
The credits sold in this transaction are tied to the environmental performance of Clean Energy's dairy RNG assets. In 2025, these seven facilities collectively produced 2.7 million gallons of negative carbon-intensity RNG intended for transportation fleet use. By selling these credits, the company is positioning itself to capture the immediate financial value of the environmental benefits produced by its infrastructure. Will Flanagan, Vice President of Strategic Development at Clean Energy, stated that the successful monetization of the full portfolio reflects the increasing demand for the environmental benefits these RNG projects deliver to the market.
Key Takeaways
- Clean Energy completed a $30.7 million sale of federal tax credits from seven RNG facilities.
- The South Fork Dairy facility in Dimmit, Texas, provided the largest portion of the deal via a $26 million ITC.
- The credit-generating portfolio produced 2.7 million gallons of negative carbon-intensity RNG in 2025.
EnergyInsyte's Take
In our view, this transaction demonstrates how RNG developers are increasingly using tax credit monetization as a core financial tool to manage liquidity. By offloading $30.7 million in credits, Clean Energy is effectively de-risking its capital intensive dairy projects. The involvement of joint venture partners like bp and TotalEnergies suggests that large-scale RNG infrastructure is becoming a standardized asset class for major energy players seeking to capture high-value environmental credits.
