Series production of electrolyzers in the gigawatt range (joint project SEGIWA)

In the SEGIWA project, which is part of the H2Giga lead project, the Silyzer 300-based water electrolyzer series developed by Siemens Energy is to be transferred from partially automated production to series production. In the subproject of Hahn-Schickard, fluorine-free membranes will be examined in an industrial context. These fluorine-free membranes as alternative to the commonly used perfluorosulfonic acid membranes, will help to significantly reduce costs and potentially allow for an more environmental friendly benign production.

In the SEGIWA project, the foundations for automated series production for water electrolyzers up to the gigawatt range are established in close cooperation with partners from industry and research. As part of the hydrogen lead projects of the BMBF, a smooth market ramp-up will be achieved, in line with the national hydrogen strategy. In order to lower the costs of producing green hydrogen in the future and to consider potentially more environmentally benign processes, Hahn-Schickard focuses on the use of fluorine-free polymers as an alternative to the commonly used perfluorosulfonic acids.

To quickly achieve industry-relevant progress, the developments will build upon developments of the project "Fluorfreie-MEA", which is also part of the H2Giga lead project. The fluorine-free membrane-electrode-assemblies (MEAs) are scaled towards the industrial level and the MEA characteristics and stability will be validated in the industrial context. As part of the BMBF's lead hydrogen projects, "SEGIWA" is helping to produce efficient and cost-effective water electrolysers of the next generation.
