Harnessing Offshore Wind for Clean Hydrogen Production in the U.S.
Key Ideas
  • Offshore wind turbines can efficiently produce clean hydrogen along the U.S. Atlantic Coast and in the Gulf of Mexico, with potential cost competitiveness by 2030.
  • NREL research evaluates scenarios of producing hydrogen from offshore wind energy using electrolysis, emphasizing the importance of technology and location.
  • Research findings suggest that by 2030, hydrogen production for less than $2 per kilogram could be achieved through a combination of factors including policy incentives and specific offshore wind-to-hydrogen setups.
  • The study highlights the significance of storage location for hydrogen, with choices such as caverns impacting cost and policy incentives playing a crucial role in cost reduction.
The U.S. National Renewable Energy Laboratory (NREL) has conducted research indicating that utilizing electricity from offshore wind turbines to produce clean hydrogen through water splitting could be economically viable, especially in regions with shallow waters and strong winds such as the U.S. Atlantic Coast and Gulf of Mexico. The study, 'Potential for large-scale deployment of offshore wind-to-hydrogen systems in the United States,' analyzed the techno-economics of offshore wind-to-hydrogen systems and emphasized the importance of technology and location in achieving cost-effective hydrogen production. The research evaluated scenarios of generating hydrogen from offshore wind energy using electrolysis, considering different production setups and locations. By 2030, it is projected that a combination of onshore electrolysis and fixed-bottom offshore wind could enable the production of hydrogen for under $2 per kilogram, potentially meeting the U.S. Department of Energy's goal for low-cost clean hydrogen. The study also explored the impact of storage location for hydrogen, highlighting that choices like cavern storage could reduce the levelized cost of hydrogen (LCOH) by 20-30%. Additionally, the researchers assessed the technical feasibility of offshore wind-to-hydrogen systems in various coastal areas, indicating that the New York Bight and Gulf of Mexico could offer favorable conditions for cost-efficient hydrogen production due to their wind capacity. The study emphasized the role of policy incentives in further reducing costs and promoting the large-scale deployment of offshore wind-to-hydrogen systems. The research, funded by the DOE's Wind Energy Technologies Office and Hydrogen and Fuel Cell Technologies Office, showcases promising indicators for the future of clean hydrogen production from offshore wind in the U.S. as technology advances and policy support evolves.
