Siemens Energy and Toray to develop partnership through PEM water electrolysis based on a new membrane technology
Siemens Energy and Toray Industries will cooperate to provide optimum solutions in order to
contribute to the realization of a carbon-neutral society in countries and regions around the world
by utilizing our hydrogen related technologies, business and global network. The joint vision of the
two companies is to advance the technology for the production of green hydrogen from innovative
PEM water electrolysis using renewable energy sources. The resulting green hydrogen can not only
be used for large-scale power generation and other electric power applications, but also for sector
coupling such as heat, transport, and industrial applications. Toray will provide Siemens Energy with Toray's proprietary hydrocarbon electrolyte membranes. The two companies will work together to
promote the installation and demonstration of these membranes in Siemens Energy's large
industrial scale PEM water electrolyzer.
