The Tokyo Metropolitan Government has adopted a feasibility study (FS project) for building a CO2 supply chain in fiscal year 2026, aiming to develop urban CO2 supply chains by exploring routes such as artificial limestone using CO2 recovered from waste incineration plants, high-purity CO2 routes, and bio-routes.
In the survey adopted by the Tokyo Metropolitan Government's public offering project, e-methane will be produced using CO2 recovered by chemical absorption from the incineration flue gas of Ota Ward Waste Incineration Plant and hydrogen supplied from the Keihinjima Green Hydrogen Production Facility, with a maximum of 25 Nm3/h, and injected into the city gas pipeline. Test verification and regulatory surveys will be conducted in fiscal 2026, and in fiscal 2027, design and economic evaluations for commercialization will be carried out. Tokyo Gas will oversee the project, and Takuma will be responsible for designing the CO2 recovery equipment and conducting economic evaluations.
