In this Policy Brief, EWI analyzes the impact of the proposed network charge reform (AgNes) on the economics of electrolyzers in Germany in the context of a stalled ramp-up. As of spring 2026, more than 3 gigawatts of planned electrolyzer capacity that are supposed to become operation in 2027 had not yet reached a final investment decision (FID).

The analysis finds that the capacity tariffs for electrolyzers of 4 to 7 euros per kilowatt per year proposed in the AgNes draft could increase the levelized cost of hydrogen (LCOH) by up to 6 percent, accounting for all tariff elements. Industrial tariffs, by contrast, could amount to up to 2 euros per kilogram in the worst case. The Policy Brief also examines whether a planned EU amendment would remove the existing exemption for electrolyzers, and analyzes grandfathering rules for projects that have already reached a final investment decision.
