A simulation-based optimization for water electrolysis is performed to identify preferable
scenarios with respect to economic as well as ecological aspects. As the electrolyzer
interacts with the wholesale electricity market and with the production of bulk chemicals
implying each specific dynamic characteristics, various and partly counteracting relevant
impulses result in a multi-objective optimization approach. In order to demonstrate
the capability of alkaline electrolytic systems to meet these dynamic demands, a 20-kW
lab-scale electrolyzer and a 2-MW large-scale electrolyzer are commissioned and tested.
