Harnessing Offshore Wind for Clean Hydrogen: NREL's Insight on US Coastal Potential
Key Ideas
  • Offshore wind power can economically produce clean hydrogen along the U.S. Atlantic Coast and in the Gulf of Mexico due to strong winds and shallow waters.
  • Technological advancements and location optimization are key to achieving DOE's goal of $1/kg for clean hydrogen by 2031.
  • Different scenarios were analyzed, concluding that by 2030, hydrogen production for less than $2/kg is feasible through offshore wind-to-hydrogen systems.
  • Optimal sites for offshore wind-to-hydrogen systems were identified, with New York Bight showing the lowest levelized cost of hydrogen due to high wind capacity.
Researchers at the National Renewable Energy Laboratory (NREL) have highlighted the potential of utilizing electricity generated by offshore wind turbines along the U.S. Atlantic Coast and the Gulf of Mexico for the production of clean hydrogen. The study, published in the Journal of Physics: Conference Series, emphasizes that areas with strong winds and shallow waters are economically viable for hydrogen production. By employing electrolyzers powered by renewable energy sources, the goal of achieving low-cost clean hydrogen, as set by the U.S. Department of Energy (DOE), is within reach. The analysis includes different scenarios, such as offshore wind plants transmitting electricity to onshore sites for hydrogen production, and splitting hydrogen from desalinated seawater at the offshore wind plant site. The research identifies New York Bight as a promising location with the lowest levelized cost of hydrogen due to its high wind capacity. Factors like technological design, location optimization, and storage methods significantly influence the cost of hydrogen production. The study underscores the importance of continued investment in offshore wind-to-hydrogen systems, considering advancements in technology and potential policy incentives. Overall, the research sheds light on the feasibility and economic viability of large-scale deployment of offshore wind for clean hydrogen production, showcasing a pathway towards a more sustainable energy future.
