Tokyo Metropolitan Government Bureau of Port and Harbor, National Institute of Advanced Industrial Science and Technology, Shimizu Corporation, Tokyo Waterfront Heat Supply (Koto Ward, Tokyo), and Tokyo Teleport Center (Koto Ward, Tokyo) are working together to develop a waterfront subcenter that utilizes hydrogen derived from renewable energy. Joint research toward decarbonization of Announced on April 28th.

A hydrogen storage alloy and a hydrogen co-firing boiler for district heat supply will be introduced in the Telecom Center Building in the Aomi district of the waterfront subcenter, the Tokyo Waterfront Heat Supply Aomi South Plant, and the C2 section of the metropolitan area. Hydrogen co-firing boilers are boilers that use city gas and hydrogen as fuel, and do not generate CO2 from hydrogen combustion. It will also supply electricity generated by hydrogen-powered fuel cells and photovoltaic power generation for building lighting.

The Port and Harbor Bureau of the Tokyo Metropolitan Government will carry out planning and coordination, provision of land owned by the Tokyo Metropolitan Government, and dissemination and enlightenment of hydrogen utilization. AIST will develop technology for hydrogen storage alloys, analyze data related to hydrogen supply and combustion, and raise awareness about the use of hydrogen. Shimizu Corporation will develop a power generation system using hydrogen and solar power, and an automated driving system using hydrogen-absorbing alloys. Tokyo Rinkai Heat Supply Co., Ltd. will install and operate hydrogen co-firing boilers, while Tokyo Teleport Center will provide and operate facilities such as building lighting.
