Hydrogen is being considered as an environmentally friendly fuel that has a potential to reduce the dependency on fossil fuels significantly. This paper presented a new cycle for combined hydrogen and power production in which, power is generated in a gas turbine cycle and the waste heat from the exhaust of the gas turbine is recovered to produce hydrogen in a five step thermochemical copper-chlorine cycle. The thermodynamic analysis of the combined cycle was performed by coding in Engineering Equation Solver (EES) software and was adapted to a combined hydrogen and power generation plant with capacity of 1 t/h hydrogen production. The results showed that the combined cycle may generate 174 MW of power, the energy efficiency may reach to 45% and the required helium mass flow rate is 48.58 kg/s.
