Fourth Information Exchange Meeting, Oakbrook, Illinois, USA , 14-16 April 2009

image of Nuclear Production of Hydrogen

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.



Degradation mechanisms in solid oxide electrolysis anodes

Nuclear Energy Agency

High temperature steam electrolysis is one of the most efficient processes for hydrogen generation from water with no CO2 emissions using electricity and heat from nuclear or concentrated solar plants. Solid Oxide Electrolytic Cells (SOEC) are the proposed technology being researched and developed for this purpose. Over a long period of operation of the cells, various sources for degradation in the cells’ electrochemical performance prevail, and hence the cell resistance increases and the process becomes inefficient. Our research is aimed at identifying the mechanisms for the loss in the electrochemical performance of the cell, particularly of the oxygen electrode, namely the anode.
