Tokyo Metropolitan Government is working to expand demand for hydrogen energy and promote its early implementation in society in order to ensure a stable supply of energy and decarbonize the city. In particular, promoting the use of hydrogen derived from renewable energy (green hydrogen) is important for realizing a decarbonized society, and efforts are underway to launch a hydrogen exchange to expand its use. In fiscal year 2024, Tokyo Metropolitan Government began trial trading of green hydrogen in order to test market-based hydrogen trading and gain knowledge, and will continue this in fiscal year 2025.

We are pleased to announce that we are now accepting applications from businesses to participate in the first round of the 2025.
