The Tokyo Metropolitan Government aims to expand demand for hydrogen energy and accelerate its early adoption in society in order to further concentrate and advance industry, accelerate innovation, and transform Tokyo into a “world-leading energy infrastructure city.”
As part of these efforts, the Tokyo Metropolitan Government will participate in “Hydrogen Technology World Expo 2026,” an international hydrogen industry exhibition to be held in Hamburg, Germany, to showcase its initiatives toward realizing a hydrogen society to the world.In addition, the Metropolitan Government will promote the technologies of small and medium-sized enterprises (SMEs) and other organizations based in Tokyo that possess technologies essential for building hydrogen-centered infrastructure, thereby enhancing Tokyo’s presence in the global hydrogen market. We are pleased to announce that the companies participating in this joint exhibition have now been selected.
