Inexperienced hydrogen research highlights methods for offshore manufacturing – TechnoNews

Because the U.S. faces important challenges in scaling up manufacturing of hydrogen in cost-effective and environmentally pleasant methods, a brand new Cornell research outlines methods to fulfill as much as 75% of the nation’s future hydrogen demand by harnessing offshore wind vitality.

The demand for hydrogen is anticipated to develop considerably within the coming a long time, with manufacturing from renewable vitality sources resembling offshore wind generators, fairly than fossil fuels, being important for hydrogen to be thought of “green.” Nonetheless, it might take 0.96 terawatts of offshore wind capability to provide 75% of the nation’s serviceable consumption potential of hydrogen, in keeping with the Cornell research revealed within the journal Power & Environmental Science.

Putting in that a lot capability would require the U.S. to drastically improve its use of offshore wind vitality, going from utilizing simply 1% of its technical useful resource potential to over 22%, stated Fengqi You, the Roxanne E. and Michael J. Zak Professor in Power Programs Engineering, who co-authored the research with graduate pupil Rishi Kaashyap Balaji.

“This is a massive increase in offshore wind energy production, but pursuing this approach would not just provide an opportunity for the U.S. to spur growth in an important energy sector, but also circumvent potential land and water use challenges from developing large-scale renewable energy infrastructure domestically,” stated Fengqi You, who can also be a senior college fellow on the Cornell Atkinson Heart for Sustainability.

The research takes a complete strategy to analyzing the financial and environmental impacts of offshore wind-based hydrogen manufacturing by using an optimization framework, life cycle evaluation, and multi-scale spatial evaluation. It examines two supply strategies—liquefied and compressed gaseous hydrogen—whereas incorporating wind velocity knowledge and state-level hydrogen demand, amongst many different parameters.

“A key finding is that transporting compressed gaseous hydrogen via pipelines offers clear economic and environmental advantages over shipping liquefied hydrogen,” Balaji stated.

“The cost and energy needed to liquefy hydrogen to -253 degrees Celsius make the liquefied hydrogen route very expensive. However, this method still warrants consideration, as building extensive pipeline infrastructure could prove to be a monumental challenge.”

The research additionally conceptualizes ‘offshore hydrogen hubs’—states clustered into geographic areas that broadly align with the U.S. Division of Power’s Regional Clear Hydrogen Hubs program introduced in 2023. The hubs comprise the required infrastructure for manufacturing, storage and end-use of unpolluted hydrogen, optimizing facility location and bringing value financial savings as much as 30% by shared infrastructure, in keeping with You.

“The East Coast emerges as a prime region of interest for offshore wind-based green hydrogen production because of high wind speeds, significant regional demand, abundant surplus potential and promising prospects for establishing export-oriented facilities to serve net-importers of hydrogen in European markets,” You stated.

Utilizing the research’s optimum pathways, producing hydrogen offshore may value between $2.50 and $7.00 per kilogram, with greenhouse gasoline emissions nicely under the 4 kilogram carbon-dioxide-equivalent benchmark. This qualifies inexperienced hydrogen for manufacturing tax credit below the Inflation Discount Act, additional growing its market competitiveness, stated You.

“Additional supportive policies, such as carbon pricing mechanisms, will be crucial,” You added. “The century-old Jones Act, for example, complicates offshore projects by requiring domestically constructed and crewed ships, yet as of 2020, no U.S.-flagged ships could perform tasks like assembling turbines at sea. Our work discusses the importance of flexible policies to address these practical challenges to the industry’s growth.”
