In a joint effort led by Kirin Brewery Company, Limited, with partners Mitsubishi Corporation, MCKB Energy Service Co., Ltd., Takasago Thermal Engineering Co., Ltd., and Miura Co., Ltd., a groundbreaking project is underway to introduce green hydrogen into the beer production process at Kirin's Chitose Brewery in Hokkaido, Japan. The initiative aims to transition part of the steam production fuel from fossil fuels to green hydrogen, with the potential to significantly reduce greenhouse gas emissions by 464 tons per year. The project involves various key aspects such as equipment installation, hydrogen supply, and hydrogen-derived steam utilization, with a clear division of responsibilities among the collaborating companies. Mitsubishi Corporation is overseeing the commercial aspects and business structuring related to hydrogen supply, while Takasago Thermal Engineering is taking charge of equipment delivery and installation. MCKB Energy Service will handle the production and supply of hydrogen-derived steam using Miura's hydrogen-fired boilers. Scheduled to begin construction in April 2025 and become operational in June 2026, the demonstration project is set to run for approximately 10 years. During this timeframe, the effectiveness of GHG reduction and technical challenges related to green hydrogen energy conversion will be assessed, contributing to the overall environmental targets of the involved companies. By sharing knowledge and expertise in energy conversion and emissions reduction, the collaboration aims to accelerate their progress towards achieving GHG emission reduction targets and fostering sustainable practices within the brewing industry. This innovative approach not only highlights the commitment of these companies to environmental sustainability but also showcases the potential for green hydrogen to revolutionize traditional industrial processes.
