Nuclear Production of Hydrogen
Fourth Information Exchange Meeting, Oakbrook, Illinois, USA , 14-16 April 2009
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.

Present status of HTGR and hydrogen production development in JAEA
Nuclear Energy Agency
The high temperature gas-cooled reactor (HTGR), which is graphite-moderated and helium-cooled, is particularly attractive due to its unique capability of producing high temperature helium gas in addition to its fully inherent and passive safety characteristics. The HTGR-based production of hydrogen, the energy carrier for an emerging hydrogen economy, is expected to be among the most promising applications to solve the current environmental issues of CO2 emission. With this understanding the development studies of HTGR cogeneration system including hydrogen production have been carried out in Japan. This paper presents the 2100 vision of JAEA on future perspective of energy supply, especially on HTGR utilisation in the field of iron manufacturing, chemical industries, oil refineries, etc. In addition, this paper presents the present status of the HTTR Project including research and development activities of HTGR reactor technology, hydrogen production technology with the thermochemical water-splitting IS process, and the commercial HTGR plant design.
