Clean Energy Fuels Corp. announced the completion of its latest renewable natural gas (RNG) facility in Marshall County, Iowa. The Marshall Ridge Dairy project is expected to produce 1.7 million gallons of low carbon-intensity RNG annually.

The three-digester facility located in State Center, Iowa, is now producing pipeline quality RNG and injecting it into the national grid. RNG is a sustainable fuel derived from organic waste that provides an immediate and significant carbon reduction in transportation. Financed through one of Clean Energy's production joint ventures and developed by Dynamic Renewables, the project totaled $42 million.

Methane from the approximately 240,000 gallons of manure produced by the 8,000-cow dairy each day will be converted into biogas and ready-to-use clean fuel for heavy-duty fleets across the country. Clean Energy is in process of filing the necessary applications to generate federal and state environmental credits.
