StaR - Stack Revolution

The aim of the joint project is to drastically reduce the costs of alkaline water electrolysis for the production of green hydrogen.

The Stack Revolution project is a BMBF-funded collaboration between science and industry as part of the H2Giga research platform with the aim of developing a particularly cost-effective cell stack for alkaline water electrolysis. The project is coordinated by the start-up WEW from Dortmund, whose founders contribute many years of industrial experience in management positions and extensive know-how in the field of electrochemical processes. As research partners in the project, the Institute of Chemical and Electrochemical Process Engineering and the Research Center for Energy Storage Technologies at Clausthal University of Technology are responsible for the characterization and further development of electrodes, as well as the model-based design of cells and stacks. RWTH Aachen University is investigating suitable joining processes for manufacturing the stacks, while OTH Regensburg is planning the production process on a gigawatt scale and developing a digital twin for the production ramp-up. As a link between stack development and the establishment of series production, the research project is completed by Rhine-Waal University of Applied Sciences, who are working on market forecasts and supply chain management issues.
