Calcium looping (CaL) systems have been proposed as a lower-cost method of CO2 capture for power plants. This paper presents the results of a techno-economic assessment of a CaL system for post-combustion CO2 capture at a pulverized coal (PC) power plant. Comparisons are made with a conventional MEA-based CO2 capture process in terms of performance and cost. Considering the significant quantities of solid flows required for a CaL process, the applicability and operational feasibility of a CaL system for new or existing PC power plants also is studied. It was found that though the CaL system has better performance than the MEA-based CO2 capture process, the capital cost of the power plant and the cost of electricity is much higher than when the MEA-based system is used.
