Overview

Techno-economic simulation reveals optimal hybrid wind-solar systems achieve levelized hydrogen costs of 5.1 €/kg across European sites, highlighting capacity-factor-driven cost estimation tools.

Key Points

Develop straightforward mathematical correlations to rapidly estimate the levelized cost of hydrogen based on regional wind and solar photovoltaic capacity factors.
Simulated water electrolysis systems optimized with genetic algorithms across 65 European sites.
Evaluated solar PV (9–20% capacity factor) and onshore wind (15–50% capacity factor) under flexible production and constant supply scenarios requiring storage.
Under optimal conditions, standalone PV and onshore wind achieved minimum levelized costs of hydrogen of 7.2 €/kg and 5.2 €/kg, respectively, while hybrid systems reached 5.1 €/kg.
Constant hydrogen demand substantially increased production costs relative to flexible operation, with the highest cost penalties observed in PV-only configurations due to large storage requirements.
