The BioCNG from Unison Solutions converts biogas to renewable natural gas with a methane quality that meets SAE J1616 fuel requirements for compressed natural gas vehicles. Systems remove hydrogen sulfide, moisture, siloxanes and carbon dioxide from the gas using technology from biogas to energy systems. All components are based on each location’s specific gas quality and requirements. The systems are capable of producing up to a 2,400 gasoline gallon equivalent per day, and can be supplemented with natural gas. Existing biogas cogeneration systems may also be upgraded to provide both fuel for the current cogeneration equipment and produce renewable natural gas for vehicle fueling. Systems provide fuel to both time-fill and fast-fill fueling stations. 563/585-0967; www.unisonsolutions.com.
