Nuclear Production of Hydrogen

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.



Possibility of active carbon recycle energy system

Nuclear Energy Agency

A new energy transformation system based on carbon recycle use was discussed. A concept of an Active Carbon Neutral Energy System (ACRES) was proposed. Carbon dioxide is regenerated artificially into hydrocarbons by using a heat source with non-carbon dioxide emission, and the regenerated hydrocarbon is re-used cyclically as an energy carrier media in ACRES. Feasibility of ACRES was examined thermodynamically in comparison with hydrogen energy system. Carbon monoxide was the most suitable for a recycle carbon media in ACRES because of relatively high energy density in comparison with hydrogen, and high acceptability to conventional chemical, steel and high-temperature manufacturing industries. A high-temperature gas reactor was a good power source for ACRES. ACRES with carbon monoxide as recycle media was expected to be one of the efficient energy utilisation systems for the reactor.
