Abstrakt: The thermochemical sulphur–iodine process is studied by CEA with the objective of massive hydrogen production using the heat coming from a high temperature reactor. A two-fold programme was set up in 2000. The main part is devoted to the study of the basic process, including optimisation of a detailed flow-sheet, thermodynamics measurements and industrial plant evaluation. In parallel, an operating flow-sheet was set-up that gives the best efficiency possible today, i.e. 35%. An innovative programme was derived that should raise the efficiency up to 50%. In parallel, international collaborations are used to develop laboratory loops to get experience from materials and components. A Bunsen section is under construction in CEA/Marcoule to be coupled later on to a sulphuric acid decomposer and a HI distiller, built in the US by SNL and GA respectively. On the other hand, several cycles are presented with a first set of analysis: the hybrid sulphur cycle, the UT_3 cycle and cerium–chloride cycle.
