Tokyo Gas Co Ltd stock (JP3573000001): Subsidiary launches Tokyo's first green hydrogen facility

Tokyo Gas subsidiary Akanetsu has started operations at Tokyo's first green hydrogen heat source facility in May 2026, marking a milestone in urban energy supply with CO2-free power and heat generation.

Akanetsu, a subsidiary of Tokyo Gas Co Ltd, commenced full-scale operations of a pioneering green hydrogen heat source facility in Tokyo's Akasaka 5-chome district in May 2026. This facility, the first for a private heat supply operator in Tokyo to use green hydrogen commercially, integrates hydrogen fuel cells for electricity and hydrogen-co-fired boilers for thermal energy, producing no CO2 emissions. The project sources green hydrogen from Yamanashi Prefecture and received support from a Tokyo Metropolitan Government grant, according to Japan Industry News as of May 2026.

The facility supplies heating, cooling, and electricity to buildings in the district, renewing Tokyo Gas's heat source infrastructure with sustainable technology. A commissioning ceremony was held recently, highlighting TBS Group's (Tokyo Gas's parent context in some reports) commitment to green energy, per GuruFocus as of May 2026. This development positions Tokyo Gas at the forefront of Japan's hydrogen economy push.
