The world’s largest green hydrogen plant has been completed in Fukushima, Japan. With the industry building momentum, the record won’t last long, but Japan is among several countries laying down significant groundwork to establish a lead within the emerging sector. The Fukushima Hydrogen Energy Research Field (FH2R) can produce up to 100 kilograms of green hydrogen per hour from water, using a 20 MW solar array alongside grid power to run a 10 MW electrolyzer. FH2R is the birthchild of a consortium including Toshiba, Tohoku Electric Power as well as Japan’s New Energy and Industrial Development Organization, costing $189 million since development started 2 years ago. As a pilot project for commercial hydrogen, initial output will be used for hydrogen-powered…
