HYTHEC : A search for a long term massive hydrogen production route

The objective of HYTHEC HYdrogen THErmochemical Cycles is to investigate the effective potential for massive hydrogen production of the S_I thermo-chemical cycle, and to compare it with the hybrid S cycle, also called Westinghouse cycle, which have in common the H2SO4 decomposition reaction (technical feasibilities, industrial and economic viabilities, including the safety aspects). The main goals of the project are the comparison of advantages and drawbacks of the S_I and WH cycles (flow-sheeting, industrial scale-up, safety and costs), the improvement of the fundamental knowledge and efficiency of the S_I cycle H2 production step, and investigation of a solar primary energy source for the H2SO4 step common to both cycles.
