Techno-economic evaluation and resource assessment of hydrogen production through offshore wind farms: a European perspective

Résumé

Hydrogen demand is expected to radically increase in the upcoming years as it is a key lever of decarbonization and offshore wind has been identified as a credible energy source to power electrolyzers. Onshore, centralized offshore and decentralized offshore electrolysis are considered in this paper, for which a detailed cost modeling is carried out. A geospatial analysis leads to a resource assessment at European scale based on the levelized cost of hydrogen (LCOH), where both the energy production potential and technical and environmental constraints are considered. The results reveal a massive resource in European seas, with LCOH decreasing from 4.5-7.5 €/kg in 2020 to 1.5-3.0 €/kg in 2050 due to the reduced costs of wind turbines and electrolyzers. A significant amount of green hydrogen-more than 1,000 TWh-could be produced at less than 3.0 €/kg in 2030 and 2.0 €/kg in 2050, making it competitive with grey hydrogen. In 2030, the mapping identifies a valuable 200 TWh resource where offshore wind-to-hydrogen projects offer a much-lower LCOH than their wind-to-power counterparts. The results of the resource assessment are detailed at country level, offering a valuable tool for energy modelers and local stakeholders. Finally, a detailed analysis of costs identifies offshore electrolysis as becoming more relevant over time: in 2020, offshore electrolysis is preferred for far-from-shore and deep-sea locations only while being located closer to shore in 2030 (over 100 km). In 2050, onshore electrolysis relevance is limited to locations close-to-shore in shallow waters.
