Technology Platform Operation Review Days, Brussels 8th-9th December 2005 HYTHEC is a short term R&D activity : 2004 to 2007 Research strategy for hydrogen production for 2005 to 2015 A constraining level of efficiency seems to be required : be careful about the definition ….HYTHEC will propose very soon its point of view about « efficiency » « Thermochemical processes are mostly proposed in the context of advanced nuclear reactors and feature prominently in the Technology Roadmap for Generation IV nuclear reactors. Alternatively, the high temperature heat from solar concentrators may be used »: Nuclear VHTR and Solar heat sources in HYTHEC. S_I cycle « generally considered the most promising thermochemical cycle »; HYTHEC considers WH cycle too
