Harnessing Offshore Wind for Clean Hydrogen Production in the U.S.
Key Ideas
  • Offshore wind-generated electricity can efficiently produce clean hydrogen along the U.S. Atlantic Coast and Gulf of Mexico.
  • Techno-economic analysis suggests achieving hydrogen production below $2/kg by 2030 using onshore and offshore electrolysis.
  • Location-specific considerations impact the cost of hydrogen production, with New York Bight and Gulf of Mexico showing promising economics.
  • Research emphasizes the need for continued investment in technology development to optimize offshore wind-to-hydrogen systems.
Researchers at the National Renewable Energy Laboratory (NREL) have highlighted the potential of using electricity from offshore wind turbines to produce clean hydrogen economically. The study analyzed the feasibility of large-scale deployment of offshore wind-to-hydrogen systems in the United States, emphasizing regions with shallower waters and strong winds as ideal for this technology. The research, published in the Journal of Physics, outlines two scenarios for generating clean hydrogen: onshore electrolysis powered by offshore wind and offshore electrolysis from desalinated seawater. By 2030, a combination of technology advancements and policy incentives could enable hydrogen production for less than $2 per kilogram. The study also addresses the importance of technological design and location selection for optimal cost-effectiveness. Factors such as wind capacity, water depth, and storage methods significantly influence the levelized cost of hydrogen. The analysis identifies the New York Bight and Gulf of Mexico as promising locations due to high wind capacity. The research underscores the need for ongoing investment in system optimization and technology development to realize the full potential of offshore wind-to-hydrogen systems.
