Hitachi, Ltd. and Tokyo Gas Co., Ltd. have collaborated to develop the first solution in Japan that digitally certifies that city gas produced using overseas biomethane as a raw material has been consumed in specific facilities. This solution, named “Powered by Carbon Neutral Gas,” will begin demonstration testing in August 2026.
Specifically, as part of Hitachi’s “Customer Zero” initiative, which it implements and verifies in-house, this solution is being applied to the gas air conditioning equipment at the Hitachi Origin Park, a corporate museum located in Hitachi City, Ibaraki Prefecture, the birthplace of Hitachi. Through this collaborative effort between the two companies, it will be possible to prove that the carbon dioxide (CO2) emissions from city gas in the target equipment are virtually zero, providing consumers with evidence of their efforts toward decarbonization. For suppliers, it will be possible to use this as a means to clearly demonstrate to consumers the environmental value of overseas-produced biomethane, thereby creating new environmental value on both the supply and demand sides.

The Tokyo Gas Group has set forth “Challenge to Net-Zero CO2 Emissions” in its management vision “Compass2030.” It is promoting initiatives in collaboration with various domestic and international businesses, combining measures such as biomethane, renewable energy, e-methane, hydrogen, and CCUS (Carbon Capture, Storage, and Sustainable Development). Both biomethane and e-methane are promising means of contributing to the decarbonization of heat. The group is promoting the introduction of overseas-sourced biomethane as a means of achieving carbon neutrality for gases that can be utilized early, aiming to accelerate these efforts. Moving forward, the group will continue to contribute to achieving the government’s goal of carbon neutrality by 2050 through various initiatives, including the introduction of overseas-sourced biomethane.
In the collaborative project promoted by Hitachi City and Hitachi, the city is working to solve social issues and create new businesses by combining on-site data and insights gained through demonstrations in Hitachi City, the demonstration field, with digital technologies such as AI. Through this initiative, the city aims to develop a new environmentally friendly regional energy supply model and will also explore the possibility of future collaboration with other collaborative projects.
