Tokyo Hydrogen Projects
From the world's largest home-fuel-cell market to Japan's first pipeline-supplied hydrogen district and Tokyo's first large-scale green-hydrogen plant — here is where hydrogen is being deployed in the city.
ENE-FARM: the home-fuel-cell revolution
Japan is the only country where residential fuel cells are a mass-market product.
World's first home fuel cell
Panasonic launched the ENE-FARM in May 2009 — the world's first commercially sold home fuel cell. It converts city gas into electricity and hot water on site, reaching up to ~97% total energy efficiency.
500,000+ installed nationwide
Cumulative ENE-FARM installations across Japan surpassed 500,000 units (industry trackers, 2023); Panasonic alone has produced over 250,000 units. Tokyo Gas is the largest installer serving the Tokyo market, with ENE-FARM an everyday sight in new Tokyo homes.
From homes to buildings
The same technology scales up: Panasonic's 5 kW pure-hydrogen fuel cell (H2 KIBOU) powers shops, offices and facilities, and the Tokyo government subsidizes commercial and industrial fuel cells (up to 2/3 of cost, max ¥333 million).
National 2030 target: 3 million
Japan's 2023 Basic Hydrogen Strategy targets roughly 3 million installed home fuel cells by 2030 — a continuing runway for ENE-FARM makers Aisin and Panasonic and the gas utilities that install them.

District & building hydrogen supply
Harumi: Japan's first hydrogen pipeline district
At the former Olympic Village, hydrogen is supplied to residential blocks through underground pipelines — a Japan first — feeding fuel cells in building common areas and refueling vehicles. The system is in practical use today.
ENEOS Harumi station & pipeline loop
ENEOS's Harumi hydrogen station accepts large commercial vehicles and, via an underground pipeline, supplies hydrogen to fuel cells installed in the surrounding Harumi district blocks — an urban energy loop at city scale.
Tokyo Big Sight on hydrogen
Part of the electricity used at Tokyo Big Sight, the city's landmark convention venue, now comes from hydrogen — visible proof that hydrogen has entered everyday Tokyo life.
Waterfront carbon-neutral district
Under the Tokyo Waterfront City Carbon Neutral Strategy, the city is exploring hydrogen mixed-combustion boilers and hydrogen piping technology using the waterfront utility tunnel — preparing the bayside district for hydrogen heat and power.

Green hydrogen production & markets
Tokyo is moving from consuming delivered hydrogen to producing and trading it.
Keihinjima: Tokyo's first large-scale green-H₂ base
Tokyo's first large-scale green-hydrogen production base at Keihinjima (Tokyo Bay coastal area) has begun operation, with production capacity slated to triple and a new production base planned by 2028. A solar-powered green-H₂ facility is also planned at the Inner Central Breakwater Reclamation Area.
First green-hydrogen station: Nishi-Shinjuku
Tokyo's first green-hydrogen refueling station, using on-site electrolysis, will be built on TMG-owned land in Nishi-Shinjuku 4-chome — bringing green fuel into the heart of the city.
Tokyo Green Hydrogen Exchange
Tokyo has been operating a trial green-hydrogen transaction platform since late 2024 — described as the world's first such platform — and signed a collaboration agreement with Germany's H2Global Foundation (Feb 2024). The Green Hydrogen Active User certification (since FY2024) rewards businesses using green hydrogen in Tokyo.
Supply-chain building
A public–private council (est. April 2024) is designing a hydrogen pipeline supply system, and the port of Kawasaki near Tokyo is positioned as a future discharge hub for overseas liquefied hydrogen. TMG signed cooperation agreements with Fukushima (Feb 2025) and Yamanashi (2022) prefectures.
