Hydrogen Production from Nuclear Energy via High-Temperature Electrolysis
- Idaho National Engineering and Environmental Laboratory, Idaho Falls, ID 83415 (United States)
High-temperature electrolytic water-splitting supported by nuclear process heat and electricity has the potential to produce H{sub 2} with an overall system efficiency near those of the hydrocarbon and thermochemical processes, but without the corrosive conditions of thermochemical processes and without the fossil fuel consumption and greenhouse gas emissions associated with hydrocarbon processes. Specifically, a high-temperature advanced nuclear reactor coupled with a high-efficiency high-temperature electrolyzer could achieve a competitive thermal-to-hydrogen conversion efficiency of 45 to 55%. A research program is under way at INEEL to develop a conceptual design for large-scale nuclear production of hydrogen via planar solid oxide electrolysis technology. The design effort is addressing solid oxide cell materials and configuration, performance, durability, operating conditions, economics, and safety. Single and multiple cell experimental studies are being conducted. Interim results indicate that this technology performs close to theoretical predictions and remains a viable means for hydrogen production using nuclear energy. (authors)
