A novel integrated model is used to evaluate the technical feasibility of a large scale Concentrating Solar Power (CSP) plant with thermochemical energy storage based on the Calcium-Looping (CaCO 3 /CaO) process. Instead of using a solar particle receiver to carry out the calcination of limestone, as the usual solution considered in previous literature, this work proposes an indirect calcination system based on using a pressurized Heat Transfer Fluid (HTF) heated up inside a tubed volumetric cavity receiver, to heat indirectly the particles for calcination to take place in an Entrained Flow (EF) reactor. After the reactor, the HTF follows a typical closed combined cycle path for power production before entering again in the receiver. On the other hand, the CaO particles and CO 2 are stored for power production under demand. Results show that full calcination of 10 kg/s can be achieved in a 51 m length and 2.5 m diameter downer reactor from an HTF releasing 17.2 MWth at temperatures higher than 1100°C. This opens a promising research line for the development of systems based on materials calcination from renewable energies. [ABSTRACT FROM AUTHOR]
