Country-specific cost projections for renewable hydrogen production through off-grid electricity systems

Renewable hydrogen is increasingly recognized as one of the key decarbonisation options compatible with EU's climate neutrality goal. We quantify possible cost reductions for renewable production until 2050 through electrolysis off-grid electricity generation systems. focus on use solar PV and on- offshore wind energy in 30 European countries. project that towards costs can fall below 2 €/kg several countries Europe. Hybrid configurations, consisting both onshore generation, generally result lower costs. Systems a relatively high level full load hours benefit from reduced share investment electrolyser component. The levelized produced via systems only compete wind-based when significant are realized, despite ultimately low expected PV-based generation. novelty this analysis it proffers an overview dependencies green production, how these could decrease over forthcoming decades across large set Specifically, we show dynamics behind projected per country highlight role technological learning have identifying most suitable locations production.
