BioCNG, LLC is a small company based in Madison, Wisconsin, operating in the renewable energy semiconductor manufacturing sector. It offers a modular gas-conditioning system that converts biogas into BioCNG, a methane-rich fuel that can power vehicles or be used for electric and thermal energy generation. Designed for economical operation at small scale, the standard skid-mounted configurations process 50, 100, or 200 standard cubic feet per minute of biogas and produce roughly 200 to 1,000 gasoline gallon equivalents of BioCNG per day. The conditioning steps remove moisture, contaminants, and CO2, delivering a product gas that is 92-98% methane and aligns with SAE J1616 and engine manufacturers’ fuel specifications. The system is already commercial and in operation at four locations, supplying CNG to fleets using gas from landfills, wastewater treatment plants, and organics digester biogas.
