Abstract

In the current paper, new systems integrating chemical-looping hydrogen (CLH) generation and the hydrogen (H₂) and oxygen (O₂) combined cycle have been proposed. The new methane-fueled cycle using CLH has been investigated with the aid of the exergy principle (energy utilization diagram methodology). First, H₂ is produced in the CLH, in which FeO and Fe₃O₄ are used as the looping material. The H ₂ and O₂ combined cycle then uses H₂ as fuel. Two types of these combined cycles have been analyzed. Waste heat from the H₂-O₂ combined cycle is utilized in the CLH to produce H₂. The advantages of CLH and the H2 and O₂ combined cycle have resulted in a breakthrough in performance. The new system can achieve 59.8% net efficiency with CO₂ separation when the turbine inlet temperature is 1300 °C. Meanwhile, the cycle is environmentally superior because of the recovery of CO₂ without an energy penalty.
