Abstract: Chemical-looping hydrogen generation (CLHG) is a chemical-looping combustion variant that allows simultaneous production of power and hydrogen. Additional integration of systems would allow the recovery of waste heat with extra advantage. A thermodynamic analysis from the exergy method point of view of an integrated syngas-fueled CLHG cycle is carried out with the aim of contributing to the conceptual understanding and development of CLHG systems. The analysis gives place to an optimization of the cycle performance in a range of working conditions. The proposed system shows a very interesting potential for trigeneration of power, hydrogen and process heating with notable overall efficiency.
