Clean Energy Fuels Corp., the largest provider of the cleanest fuel for the transportation market, and Maas Energy Works, the nation’s largest dairy digester developer, have entered a new joint development agreement to build nine renewable natural gas (RNG) production facilities at dairy farms across seven states.
The new partnership will include dairies located in Colorado, South Dakota, Georgia, Florida, Iowa, Nebraska and New Mexico, and will collect the manure from a combined herd size of approximately 35,000 cows preventing the methane emissions from entering the atmosphere, according to a news release.
The nine projects, each subject to finalizing diligence before beginning construction, are expected to be completed in 2026 and will produce up to an estimated 4 million gallons of ultra-clean RNG annually, a negative carbon-intensity transportation fuel which will make its way into Clean Energy’s nationwide network of RNG stations.
Industry pioneer Maas Energy Works has completed over 60 dairy digester projects over the past decade. The team specializes in lagoon cover digesters which involve a large tarp over a manure lagoon to capture the methane emissions. This process makes these facilities significantly less expensive to build and operate compared to tank digesters seen at other RNG plants. Financed by Clean Energy, the nine sites are forecasted to cost approximately $130 million in total.
“This JV brings together expertise from a seasoned RNG developer and producer and Clean Energy’s extensive RNG distribution network and growing RNG customer base. We are excited to continue our long working relationship with the team at Maas Energy Works to get these facilities online and producing pipeline quality RNG to help supply our transportation fleet customers with clean fuel to help them meet their sustainability goals,” said Clay Corbus, senior vice president at Clean Energy.
“This joint venture is clear proof that family farms paired with private businesses are an unstopped force in achieving decarbonization. If the markets for renewable fuels are clear and consistent, then American’s biogas industry will deliver. We will soon be capturing fugitive manure emissions and turning them into carbon-negative truck fuel with our partners at Clean Energy,” said Daryl Maas, CEO of Maas Energy Works.
