The complementarity between Spanish photovoltaics and Danish offshore wind power could underpin a European green hydrogen market by enabling renewable hydrogen production and exports at costs close to €2/kg.

An international research team has assessed a joint strategy between Spain and Denmark to develop cost-competitive European renewable hydrogen corridors, leveraging the seasonal complementarity between Spanish photovoltaic generation and Danish offshore wind power. To this end, they developed a high-resolution techno-economic model to optimize full green hydrogen value chains – including production, storage, and export – under an “off-grid” configuration, without reliance on external electricity imports or grid backup.

The research is based on a key assumption for Europe’s energy transition: a significant mismatch exists between regions with the highest renewable potential and future hydrogen demand centres. In this context, Spain emerges as a leading candidate for solar PV-based hydrogen production, with yields exceeding 1.7 MWh/kW per year, while Denmark stands out for offshore wind capacity factors above 50% and plans to deploy 4–6 GW of electrolysis capacity by 2030.
