Status of the development of the General Atomic thermochemical water-splitting cycle

Progress in the development of the General Atomic (GA) sulfur-iodine thermochemical water-splitting cycle over the last 18 months is reported in this paper. The results of the work carried out during the last year have demonstrated that thermochemical water splitting by the suflur-iodine cycle is a feasible process and have provided some confidence that thermal efficiencies as high as 50% are achievable.
