General process scheme for hydrogen production and storage from wind energy via electrolysis or from the electric grid. Wind power data were modeled according to data from Decker et al. for different locations, here: Cuxhaven in Germany, based on weather data from 2013 [18]. A Electricity from the grid; B–D electricity from the wind park: only surplus of electricity (B), the load regime for electrolysis between the base load of the grid and curtailment at an upper limit (C) and full spectrum to high electricity generation with curtailment at a lower limit and (D) as off-grid electricity supply
