The GA sulfur-iodine water-splitting process - A status report

The sulfur-iodine water-splitting cycle has been under development at General Atomic Company (GA) since 1974. The main attributes of the cycle discussed are that its thermal efficiency is expected to be high (about 50%) and that it can be conducted as an all-liquid and gas-phase process, a characteristic that should give it considerable engineering advantage over any cycle requiring solids handling.
