The meta-analysis of [1] shows that, according to several studies, an electrolysis capacity of more than 100 GW is required in the future energy system in Germany. If such an electrolysis capacity is to be installed in the course of the next few decades, it will be necessary to ramp up the market in good time so that market-driven, reliable and inexpensive plants can be made available.
