Harnessing Offshore Wind for Clean Hydrogen Production in the United States
Key Ideas
  • Researchers at NREL suggest that offshore wind turbines along the U.S. Atlantic Coast and in the Gulf of Mexico can economically produce clean hydrogen from water splitting.
  • The DOE aims to reduce clean hydrogen production costs to $2 per kilogram through the Hydrogen Shot initiative, making it cost-competitive with traditional carbon-intensive methods by 2030.
  • Two scenarios were evaluated: one involving onshore electrolysis and another where hydrogen was produced from desalinated seawater at the offshore wind site, showing promising cost reduction potential by 2030.
  • Offshore renewable hydrogen production poses new challenges but offers significant potential for large-scale operations, especially in regions with abundant wind resources and connection to clean hydrogen hubs.
Researchers at the National Renewable Energy Laboratory (NREL) have published a paper suggesting that offshore wind turbines in the United States, particularly along the U.S. Atlantic Coast and in the Gulf of Mexico, can be utilized to economically produce clean hydrogen through water splitting. This aligns with the U.S. Department of Energy's (DOE) goal of achieving low-cost clean hydrogen production. The DOE aims to drive down costs to $2 per kilogram through its Hydrogen Shot initiative by 2030, making clean hydrogen cost-competitive with traditional carbon-intensive methods. The research conducted simulations to analyze the techno-economics of hydrogen production from offshore wind energy, indicating that by 2030, a combination of policy incentives and technology advancements could enable hydrogen production for less than $2 per kilogram. Two scenarios were evaluated, one involving onshore electrolysis and the other where hydrogen was produced from desalinated seawater at the offshore wind site. While the latter scenario showed promising cost reduction potential, it also highlighted the need for additional infrastructure and technological advancements for large-scale production. Offshore renewable hydrogen production, despite being a new field, offers significant potential for decarbonizing hard-to-electrify sectors. The research identifies regions with strong wind resources, like the Gulf of Mexico and New York Bight, as promising locations for offshore wind farms coupled with clean hydrogen production, especially in proximity to DOE's Regional Clean Hydrogen Hubs. The study emphasizes the need for novel configurations and infrastructure to connect electrolyzers to offshore wind farms for efficient large-scale hydrogen production.
