JAPAN, AUG 1, 2018 -- Asahi Group Holdings, Ltd. announced on May 15, 2018, that it had established a process to purify the biomethane gas (biogas) produced in the wastewater treatment process at breweries into high-purity biogas suitable for Solid Oxide Fuel Cell (SOFC) power generation. Using the purified biogas as a fuel, Asahi conducted a power generation experiment on a SOFC power generation test device jointly developed with Kyushu University Next-Generation Fuel Cell Research Center, and successfully generated electricity for more than 2000 consecutive hours.
Asahi has introduced anaerobic wastewater treatment equipment at its 13 breweries in Japan, allowing it to treat wastewater discharged from the manufacturing process by a fermentation method to produce biogas. This plant-derived, carbon-neutral biogas is then burned in boilers, etc., and reused as heat energy in the facilities. If the biogas were to be used in SOFC power generation to produce electricity more efficiently, however, further reductions in CO2 emissions can be expected.
