The image illustrates seasonal hydrogen storage for reconversion to electricity within the company. It features a 10 kW Batarow PEM electrolyzer paired with a 138 kWh redox vanadium flow battery for efficient hydrogen storage. The Simulink model shows how the hydrogen storage system, combined with the battery, doubles the amount of hydrogen produced with the same PV system size. The graph highlights that with the right hydrogen storage capacity and battery size for the electrolyzer, grid consumption is halved, and even water production is possible during the German winter.
