Solar driven large scale uninterrupted power production can be accomplished with a combination of Concentrated Solar Power (CSP) plant and a Thermochemical Energy Storage (TCES) based on a Calcium Looping (CaL) process. Thermal energy can be stored in the form of chemical energy due to calcination reaction and released back as thermal energy during the carbonation reaction (CaO + CO2 ↔ CaCO3). This paper presents the preliminarily design, integration, and simulation of such process plant in AspenPlusTM by considering solar energy in the system. This includes indirect solar heated calcination by explicitly heating up CO2 at high temperatures at a concentrated solar heat exchanger (receiver), where CO2 is directly imported into the calciner not only to preheat solids, but to provide the appropriate energy for the highly endothermic calcination reaction. The global efficiency of the integrated system reaches 31.5 %. A parametric analysis is presented on the effects of key parameters, such as the carbonation pressure, the CO2 inlet temperature to calciner, and CaO storage temperature.
