Chemical Looping Technologies for H2 Production With CO2 Capture: Thermodynamic Assessment and Economic Comparison

The results of the analysis show that both new concepts can achieve higher H2 reforming efficiency than a conventional plant when integrated with CO2 capture (+8-10% higher). The improvement in the performance of the plant is accompanied with an efficiency penalty of 4-6% and the cost of CO2 avoidance varies from 20-85 €/tonCO2.
