en.Wedoany.com Reported - TBS Group's subsidiary Akanetsu has officially launched its hydrogen heat source facility in Akasaka, Tokyo, with full operation scheduled to begin in May 2026. This facility is the first commercial project in Tokyo where a private heat supply operator receives and stores green hydrogen for simultaneous use in power generation and heat supply.

Akanetsu supplies heating, cooling, and electricity to multiple buildings in Akasaka 5-chome, Minato Ward, Tokyo. During the renewal of its heat source facilities, the company introduced hydrogen utilization equipment designed with a safety-first approach, adopting green hydrogen as a next-generation energy option. The system uses pure hydrogen fuel cells for power generation, producing no carbon dioxide during operation, while hydrogen co-firing boilers generate steam to provide thermal energy.

Hydrogen is regularly transported from Yamanashi Prefecture, with the project receiving funding from the Tokyo Metropolitan Government. At a maximum hydrogen co-firing ratio of 50% by volume, each boiler can reduce carbon dioxide emissions by approximately 21% compared to using city gas alone. The hydrogen storage tanks utilize hydrogen storage alloys internally, enabling safe low-pressure storage.

TBS Holdings President and CEO Ryujiro Abe stated that the full operation of this facility represents a significant step toward decarbonizing urban infrastructure. Tokyo Governor Yuriko Koike noted that hydrogen energy simultaneously addresses the goals of stable energy supply and decarbonization. Akanetsu Representative Director and President Morimasa Takagi remarked that the project overcame years of challenges to reach this milestone.
