Nuclear Production of Hydrogen

Third Information Exchange Meeting, Oarai, Japan, 5-7 October 2005

Hydrogen has the potential to play an important role as a sustainable and environmentally acceptable energy carrier in the 21st century. Since natural sources of pure hydrogen are extremely limited, it is necessary to develop technologies to produce large quantities of hydrogen economically. The currently dominant technology for producing hydrogen is based on reforming fossil fuels, a process which releases greenhouse gases. Hydrogen produced by water cracking, using heat and surplus electricity from nuclear power plants, requires no fossil fuels and results in lower greenhouse gas emissions. This conference proceedings presents the state of the art in the nuclear production of hydrogen and describes its associated scientific and technical challenges.

Hide / Show Abstract

Sulfur-based hybrid cycle (SHC) process has been attracted much attention as a mass production process of hydrogen, which consists of an electrolysis step, 2H2O+SO2 ¨ H2 + H2SO4 (353 K), and a thermal decomposition step, H2SO4 ¨ H2O + SO2 + 1/2O2 (1123 K).
