Toray Industries, Inc. in Tokyo has been selected by the Ministry of Economy, Trade and Industry to develop a gigawatt-class mass production system for electrolyte membranes used in water electrolyzers as part of the Green Transformation Supply Chain Development Support Program. They have innovated a hydrocarbon-based electrolyte membrane that improves the performance of Polymer Electrolyte Membrane (PEM) water electrolyzers, crucial for green transformations in industries. Collaborating with Yamanashi Prefecture and other companies, Toray is working on a large power-to-gas system to decarbonize the Suntory Natural Water Minami Alps Hakushu Water Plant and the Suntory Hakushu Distillery in Hokuto, Yamanashi Prefecture. The recent installation of a 16-megawatt power-to-gas system marks progress in converting renewable energy into hydrogen to replace fossil fuels in high-energy-consuming equipment. The Ministry approved Toray's ¥56 billion investment plan to achieve a production capacity exceeding 10 gigawatts in water electrolyzer capacity by fiscal 2028. The market for electrolyte membranes is expected to grow significantly, surpassing 100 billion yen annually in the early 2030s, driven by the increasing utilization of renewable energy.
