Offshore Wind to Hydrogen: NREL Identifies Promising US Locations
Key Ideas
  • NREL researchers found that generating clean hydrogen from offshore wind along the US Atlantic Coast and in the Gulf of Mexico shows economic promise due to shallow waters and strong winds.
  • Their study evaluated two scenarios involving electrolysis powered by offshore wind and identified ideal coastal areas for wind-to-hydrogen systems, projecting production costs below $2 per kilogram by 2030.
  • The analysis considered different hydrogen production methods, infrastructure requirements, and storage options, highlighting the potential for large-scale deployment of offshore wind-to-hydrogen technology.
  • Policy incentives and technological advancements are key factors in driving down costs and promoting the integration of offshore wind and clean hydrogen production for decarbonizing hard-to-electrify sectors.
A recent study by researchers at the National Renewable Energy Laboratory (NREL) has identified promising locations off the US coastlines for the installation of technology that converts electricity generated by offshore wind turbines into clean hydrogen. The study suggests that regions with shallow waters and strong winds, such as the US Atlantic Coast and the Gulf of Mexico, offer economic advantages for producing clean hydrogen from offshore wind. The NREL study evaluated two scenarios for generating clean hydrogen using electrolysis powered by offshore wind, aiming to achieve production costs below $2 per kilogram by 2030. The analysis considered factors such as the depth of water at potential sites, with turbines either fixed to the ocean floor or on floating platforms depending on the location. The study also examined different methods of hydrogen production, such as using freshwater onshore or desalinated seawater offshore, each with varying infrastructure requirements. The researchers emphasized the importance of policy incentives in driving cost reductions and promoting the adoption of offshore wind-to-hydrogen systems. Furthermore, the study highlighted the significance of technological advancements and system-level optimization in realizing the potential for large-scale deployment of offshore wind-to-hydrogen technology. The researchers also explored storage options for the produced hydrogen, including underground pipes, rock caverns, and salt caverns. Overall, the study showed promising indicators for the future of offshore wind-to-hydrogen systems, with the potential to decarbonize hard-to-electrify sectors. As clean hydrogen production and offshore wind technologies continue to evolve, the integration of these systems could play a crucial role in achieving cost-competitive and sustainable hydrogen production.
