Integrated techno-economic framework for nuclear hydrogen production: assessing the role of high temperature steam electrolysis and safety considerations

This manuscript presents a comprehensive techno-economic assessment of nuclear-integrated hydrogen production using high-temperature steam electrolysis (HTSE) in the U.S. Gulf Coast region. Recognizing the growing importance of hydrogen as both an energy carrier and a chemical feedstock, the study evaluates the feasibility of co-locating HTSE facilities with existing nuclear power plants (NPPs) to enhance production efficiency and cost-effectiveness. It highlights the advantages of HTSE over traditional low-temperature electrolysis, particularly its ability to leverage both thermal and electrical energy from NPPs. A novel deployment framework is introduced, integrating hydrogen market analysis, techno-economic evaluation, and safety assessments. The findings underscore the economic viability of hydrogen production under current market conditions, including fluctuating natural gas prices and the impact of production tax credits provided by the Inflation Reduction Act. A case study in the Gulf Coast region demonstrates the potential for strategic hydrogen production to meet growing industrial demand while ensuring safety and regulatory compliance. Overall, this research contributes to advancing nuclear-integrated hydrogen production as a sustainable energy solution.
