The National Energy Technology Laboratory’s (NETL) Research and Innovation Center (RIC) has been conducting laboratory-scale tests to develop a new chemical looping combustion (CLC) oxygen carrier (OC) having copper, iron, and alumina components. This OC, designated as the Gen-2 OC throughout this report, has high maximum oxygen capacity and has been tested extensively in the RIC methane-fueled chemical looping reforming. A screening analysis has been conducted to estimate the performance and cost of CLC when utilizing the Gen-2 OC. In this report, the performance and cost results are compared to those of a range of previously assessed CLC OCs to provide a basis to establish the relative merits and issues associated with the Gen-2 OC. Base load CLC power plants utilizing the Gen-2 OC and the three comparison OCs considered in this assessment (Fe2O3-, CuO-, CaSO4-based) are estimated to have thermal efficiency and cost of electricity (COE) characteristics potentially superior to those of the equivalent conventional pulverized coal (PC) power plant applying conventional, amine-based CO2 capture technology. The current assessment does not address flexible plant operation. An evaluation of the CLC plant designed for flexible operation would need to include a comparable PC plant designed for flexible operation.
