Techno-Economic Comparison of Combined Cycle Power Plants with Pre-Combustion Co2 Capture Via Two Different Reforming Methods: Chemical Looping Reforming and Gas Switching Reforming

The potential of gas switching chemical looping technology to eliminate the energy penalty of CO2 capture

“…A brief schematic of the four chemical looping processes is given in Figure 30: In the reforming process (GSR), a natural gas fuel is converted to a syngas stream, as opposed to a complete fuel conversion occurring in combustion. The syngas produced can be later employed as feedstock for flexible H2 production in a WGS unit or electricity in a combined cycle [55]. In the water splitting process, an additional steam stage is used to obtain H2, while attaining full conversion of the fuel in the reduction reactor using an iron oxide oxygen carrier.…”
