Hydrogen has the potential to play an important role as a sustainable and environmentally acceptable energy carrier in the 21st century. This report describes the scientific and technical challenges associated with the production of hydrogen using heat and/or electricity from nuclear power plants, with special emphasis on recent developments in high-temperature electrolysis and the use of different chemical thermodynamic processes. Economics and market analysis as well as safety aspects of the nuclear production of hydrogen are also discussed.



Status of the INL high-temperature electrolysis research programme – experimental and modelling

Nuclear Energy Agency

This paper provides a status update on the high-temperature electrolysis (HTE) research and development programme at Idaho National Laboratory (INL), with an overview of recent large-scale system modelling results and the status of the experimental programme. System analysis results have been obtained using the commercial code UniSim, augmented with a custom high-temperature electrolyser module. The process flow diagrams for the system simulations include an advanced nuclear reactor as a source of high-temperature process heat, a power cycle and a coupled steam electrolysis loop. Several reactor types and power cycles have been considered, over a range of reactor coolant outlet temperatures.
