On a 55-acre dairy farm in rural Minnesota, manure from more than 2,000 milking cows is being turned into ultra-low-carbon vehicle fuel that is sent directly into interstate natural gas pipelines. The renewable natural gas (RNG) facility at Ash Grove Dairy near Lake Benton processes up to 60,000 gallons of cow manure every day. Built by Dynamic Renewables and funded through a $22 million joint venture led by Clean Energy Fuels Corp, the plant converts farm waste into clean biomethane for commercial transportation fleets across North America. At full capacity, the Minnesota facility is expected to produce around 480,000 gasoline-gallon equivalents of negative carbon-intensity fuel every year. The project was showed in industry reports by Biofuels Digest and Farm Progress after Clean Energy Fuels announced that the facility had officially connected to the national pipeline network.
