Seals for hydrogen production via electrolysis

By providing seals for electrolyzers, Freudenberg Sealing Technologies is contributing to sustainable hydrogen production based on solar and wind power. The seals are designed for automated production, enabling a rapid buildup of high manufacturing capacities.

Global production capacity for green hydrogen could increase to more than 250 gigawatts by 2030, according to a study by the International Renewable Energy Agency (IRENA). The technologies needed to split water by using green power (electrolysis) are already well advanced. Experts believe that membrane
electrolysis, which in principle works like a fuel cell in reverse, is particularly suitable for intermittent production with a highly fluctuating power supply. However, like the established process of alkaline electrolysis, systems for polymer membrane electrolysis so far have only been built in small quantities. Series production has only become attractive with the increased climate protection plans in China, Europe and the U.S. By now, the first manufacturers are planning gigafactories where electrolyzers with a high degree of automation can be built at significantly lower costs.
