A recent Cornell study delves into the potential of offshore wind energy in meeting a significant portion of the US's future hydrogen demand, crucial for achieving green and sustainable hydrogen production. The study highlights the necessity of transitioning from fossil fuels to renewable sources like offshore wind turbines for hydrogen production to be environmentally friendly. To produce 75% of the nation's serviceable consumption potential of hydrogen, it would require a substantial increase in offshore wind capacity, emphasizing the importance of harnessing this energy source. The research employs an optimization framework, life cycle assessment, and multi-scale spatial analysis to evaluate the economic and environmental impacts of offshore wind-based hydrogen production. It compares the delivery methods of liquefied and compressed gaseous hydrogen, with compressed gaseous hydrogen via pipelines showing clear advantages in terms of cost and energy efficiency. Additionally, the study introduces the concept of 'offshore hydrogen hubs,' strategically clustered states with infrastructure optimized for clean hydrogen production, storage, and end-use, aiming for up to 30% cost savings through shared facilities. The study identifies the East Coast as a promising region for offshore wind-based green hydrogen production due to favorable conditions like high wind speeds, regional demand, surplus potential, and export opportunities. Cost estimates for producing offshore hydrogen range between $2.50 and $7.00 per kilogram, with low greenhouse gas emissions, meeting the criteria for production tax credits. To further support the growth of offshore wind and hydrogen production, the study emphasizes the importance of supportive policies such as carbon pricing mechanisms and revisiting regulations like the Jones Act, which currently poses challenges to offshore projects. The study envisions a sustainable pathway towards green hydrogen production, emphasizing the economic viability and environmental benefits of utilizing offshore wind energy.
