Clean Energy’s RNG digester at Tri-Cross Dairy begins production

Clean Energy announced the successful completion and operational launch of its latest renewable natural gas – RNG – production facility at Tri-Cross Dairy in Viborg, South Dakota. The new RNG facility sits on a 5,000-cow dairy farm and is forecasted to produce 1 million gallons annually of negative carbon-intensity RNG. The construction costs of the RNG production facility, which includes the build of digesters and processing plant, totaled $34M and was completed in December 2023. The injecting of pipeline quality RNG began shortly after completion. Clean Energy is in process of filing the necessary applications to generate federal and state environmental credits. Financing for the Tri-Cross Dairy project is backed by one of Clean Energy’s RNG production joint ventures and developed by Dynamic Renewables. The facility is one in a series of projects in the Midwest for which the companies have partnered together.
