To ensure a stable supply of energy and achieve decarbonization, the Tokyo Metropolitan Government is working to expand demand for hydrogen energy within the city and quickly implement it in society, including by promoting the spread of fuel cell (FC) mobility.
We are pleased to announce that the Tokyo Metropolitan Government will host the international conference on hydrogen energy, “HENCA ^[Note] Tokyo 2025,” as detailed below. This will share information on Tokyo’s efforts and the latest initiatives by cities and companies overseas, demonstrate collaboration between cities and between the public and private sectors, and strengthen efforts to build an international hydrogen supply chain.
Now that the climate crisis has become an urgent issue, the Tokyo Metropolitan Government will pool the wisdom and experience of cities, private companies, and organizations around the world to steadily advance the social implementation of green hydrogen, in order to change the world and its future through energy transition.

[Note] HENCA is an abbreviation for Hydrogen Energy Conference for Action.
