A recent study from UNC-Chapel Hill's Gillings School of Global Public Health highlights the potential of green hydrogen as a clean and cost-effective fuel. The research, published in Renewable and Sustainable Energy Reviews, emphasizes that green hydrogen, produced from water through electrolysis, could soon rival grey hydrogen in cost efficiency. Dr. Noah Kittner and doctoral student Rui Shan analyzed strategies to promote green hydrogen adoption, focusing on the role of U.S. tax credits. The study suggests that tax credits provided by the Inflation Reduction Act could make green hydrogen more affordable than grey hydrogen, driving a shift towards cleaner fuels. However, the study also points out the need for more industries to adopt green hydrogen to achieve economies of scale. The researchers recommend building new solar and wind farms dedicated to hydrogen production to lower costs and reduce reliance on fossil fuels. Additionally, they propose a targeted approach for tax credits, directing incentives towards industries most prepared to transition to green hydrogen. This strategy could significantly increase green hydrogen use and reduce greenhouse gas emissions at a lower cost to the federal government. Overall, the study emphasizes the importance of not only financial support but also building a customer base for green hydrogen to ensure its long-term affordability and positive environmental impact.
