As part of the "Elektrolyse-BW" project, funded by the Ministry of Economic Affairs, Labor and Housing in Baden-Württemberg, a product-related system demonstrator is being built. The alkaline pressure electrolyzer is to include as many process and electrotechnical components (e.g. pumps, valve technology, power electronics, control technology) and manufacturing technologies from Baden-Württemberg as possible.
The heart of an electrolyzer is the electrolysis block, which significantly influences the efficiency and costs of hydrogen production. Therefore, the focus of the accompanying research activities is on the key components of the electrolysis block. The Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW, Stuttgart) is in charge of the electrolysis block concept and the preparation for industrialization. At the German Institutes for Textile and Fiber Research (DITF, Denkendorf), research is being conducted into innovative, efficient and robust membrane materials. The German Aerospace Center (DLR, Stuttgart) is working on processes for the catalytic coating of electrodes using the plasma spray method. Hahn-Schickard-Gesellschaft für angewandte Forschung (Hahn-Schickard, Stuttgart) is developing cell-integrated sensor technology in the form of a foil system with associated readout electronics in order to be able to record important operating variables directly at the point of gas generation. In the run-up to the conference, a broad-based industrial dialog was conducted with companies and multipliers from Baden-Württemberg.
In themed workshops, interested companies were able to find out about electrolysis technology and the respective requirements for the individual components and assemblies. The ongoing dialog with companies and multipliers ensures practical relevance for the regional economy and successful technology transfer.
