This work presents the results of the techno-economic analysis of cement plants with Calcium looping (CaL) process for CO2 capture. Two different CaL integration approaches are compared, namely the tail-end CaL with fluidized bed reactors and the integrated CaL with entrained flow reactors. Specific primary energy consumption for CO2 avoided (SPECCA) of 3.3 and 3.8 MJLHV/kgCO2 have been calculated for the integrated and the tail end CaL cases respectively. Cost of CO2 avoided between 50 and 56 €/tCO2 have been obtained.
