Tokyo Electric Power Company to build a hydrogen production facility alongside a mega-solar plant in Koto Ward.

Tokyo Electric Power Holdings (Chiyoda Ward, Tokyo) announced on June 20 that it will collaborate with the Tokyo Metropolitan Government to install a mega-solar and green hydrogen production facility at the "Outer Central Breakwater Landfill" in Koto Ward. The basic design is scheduled for fiscal year 2025, with operations aimed to begin in fiscal year 2028.
The plan includes the establishment of solar power generation with an output of over 1MW and an "electrolysis facility" that produces 100Nm³ of hydrogen per hour by splitting water using electricity. The hydrogen produced here will be compressed and transported for use in power generation and factories. Additionally, water supply facilities and management buildings will also be developed.
Hydrogen is expected to serve as a solution to the weaknesses of solar and wind energy, which are affected by weather, as it can store large amounts of energy for long periods. Green hydrogen is an important energy source for a decarbonized society, as it does not emit CO₂ during production.
Tokyo Electric Power has a track record of utilizing renewable energy and hydrogen, including hydrogen demonstration projects in Yamanashi Prefecture, and aims to further promote the adoption of renewable energy and hydrogen in Japan through this initiative.
