- This project describes a ”third way” primary heat source to replace problematic solar and nuclear heating for thermo-chemical hydrogen synthesis. An Integral Gasification/Thermo-Chemical (IGTC) electric plant recovers heat from recycled char in a commercially available gasifier to a thermo-chemical hydrogen cycle, which replaces an inefficient heat recovery steam generator and engine. Product hydrogen and some syngas then fire a station gas turbine-generator, while methanation of remaining syngas provides liquefied methane for export and vehicle use. Candidate thermo-chemical cycles, including hybrid sulfur, sulfur-iodine and manganese oxide, operate below the 1200–1500 oC gasifier exit and water splitting temperature.

I would be very interested to see how a thermochemical recovery system followed by hydrogen storage then combustion in a gas turbine is going to be more efficient than a heat exchanger and steam turbine. It sounds a bit complicated and the more complexity you have the more opportunity for losses and consequent inefficiencies. Suggest you examine the efficiency calculations carefully to make sure you're better off. And the improvement should be substantial as in practice plants will never be as efficient as theory initially suggests!
