Mitsubishi Corporation, Kirin Brewery, MCKB Energy Service Co., Takasago Thermal Engineering, and Miura are collaborating on a green hydrogen demonstration project at Kirin Brewery Hokkaido in Chitose. The project involves converting part of the fuel used in the steam boiler to green hydrogen to be used in the beer production process. This switch is anticipated to reduce GHG emissions by 464 tons annually and replace up to 23% of the heat demand with hydrogen. Various companies have specific roles in the project: Kirin Brewery focuses on using hydrogen-derived steam, Mitsubishi Corporation manages commercial aspects, Takasago Thermal Engineering deals with hydrogen production and facility design, and Miura provides hydrogen-fired boilers. The construction is set to begin in April 2025, with operations starting in June 2026 for a 10-year demonstration period. This initiative aligns with the companies' goals of achieving sustainability and reducing GHG emissions. Kirin Brewery aims for net-zero greenhouse gas emissions by 2050, while Mitsubishi Corporation targets net-zero GHG emissions and a low-carbon energy supply. Through this project, the companies aim to enhance their technical knowledge of energy conversion to advance their sustainability objectives.
