US$34 Million, US$38 Million RNG Facilities Begin Production In South Dakota
Clean Energy Fuels Corporation (Clean Energy) has completed a new renewable natural gas (RNG) production facility at Drumgoon Dairy in Lake Norden, South Dakota. The 6500-cow dairy farm is expected to supply 1.66 million gallons (6.28 million liters) of negative carbon-intensity RNG annually to the transportation market when at full capacity. Construction of the US$38 million RNG digester project was completed in early-December 2023 and injection into the interstate natural gas pipeline system of the RNG began within weeks. The RNG produced at Drumgoon will be virtually stored until all pathways for federal and state environmental credits are approved, and a carbon-intensity score is assigned to the RNG, expected in the first half of 2024.
“Completion of the RNG project at Drumgoon Dairy, along with several others that are right behind it, is already making a contribution to controlling harmful greenhouse gas emissions,” said Clay Corbus, senior vice president of renewables at Clean Energy. “Being a multi-generational operation, Drumgoon’s owners are always thinking about the future, whether it’s bringing in the latest technology to better track and monitor their cows or transforming their herd to antibiotic-free. Adding an RNG digester that captures the methane produced by Drumgoon’s cows and turning it into a clean fuel is the ultimate recycling project.”
