A small-scale PEM fuel cell
Siemens and Toray link up on PEM electrolysers
Japanese government backs project to deploy Toray hydrocarbon electrolyte membranes in Japan
Germany’s Siemens Energy is working with Japanese chemicals company Toray on the development of large-scale proton-exchange membrane (PEM) electrolysers for green hydrogen production in Japan. The project will receive Japanese government funding from the Ministry of Economy, Trade and Industry and from the publicly owned New Energy and Industrial Technology Development Organization. Toray says it will provide Siemens with its proprietary hydrocarbon electrolyte membranes for the project. Siemens is rapidly scaling up the size of the electrolysers it offers to the market, with the next key targets being 100MW by around 2023 and 1GW by 2028, as it looks to lower green hydrogen production costs
