Process simulation and economic analysis of the Calcium Looping Process (CLP) for hydrogen and electricity production from coal and natural gas

► The Calcium Looping Process integrates the water-gas shift with CO2 capture. ► Application of the CLP to coal gasification and methane reforming plants is modeled. ► Recovery of high-quality heat results in significant co-production of electricity. ► The cost of producing H2 and electricity with CO2 capture is reduced by 9-12%.
