Abstract

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 Westinghouse (WH) cycle. The project aims to conduct flow-sheeting, industrial scale-up, safety and costs modeling, to improve the fundamental knowledge and efficiency of the S-I cycle H2 production step, and to investigate a solar primary energy source for the H2SO4 decomposition step which is common to both cycles. Initial reference flow-sheets for S-I and WH cycles have been prepared and compared. First data and results are available now on the coupling of S-I cycle with a Very High Temperature Nuclear Reactor, scale-up to industrial level and cost estimation, improvement of the knowledge of the HIx mixture (S-I cycle) and membrane separation, splitting of sulphuric acid using a solar furnace, and plant concepts regarding the WH process.
