Calcium looping (CaL) is one of the potential TES processes for the future generation of CSP plants coupled with highly efficient power cycles. Research on CaL as a system for thermochemical energy storage (TCES) has focused on efficiency enhancement based on hybridization with other renewable technologies. This work proposes a novel solid management system to improve the efficiency of a CaL TCES system. The inclusion of a solid–solid separation unit after the carbonation step could lead to energy and size savings. The role of segregation between carbonated and calcined material on plant requirements is assessed, given the experimental evidence on the potential classification between more and less carbonated particles. The results show lower energy (up to 12%) and size (up to 76%) demands when the circulation of less carbonated material through the CaL TCES system diminishes. Moreover, under a classification effectiveness of 100%, the retrieval energy could increase by 32%, and the stored energy is enhanced by five times. The present work can be a proper tool to set the design and size of a CaL TCES system with a partial separation of the carbonated material. info:eu-repo/grantAgreement/ES/DGA/T46-20R info:eu-repo/grantAgreement/EC/H2020/727348/EU/SOlar Calcium-looping integRAtion for Thermo-Chemical Energy Storage/SOCRATCES This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 727348-SOCRATCES info:eu-repo/grantAgreement/ES/MCIU/FPU17-03902 info:eu-repo/grantAgreement/ES/MICIU EST19-00144 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 3.2 2024 ENERGY & FUELS 112 / 182 = 0.615 2024 Q3 T2 0.713 2024 Engineering (miscellaneous) 2024 Q1 Electrical and Electronic Engineering 2024 Q2 Energy (miscellaneous) 2024 Q2 Renewable Energy, Sustainability and the Environment 2024 Q2 Fuel Technology 2024 Q2 Control and Optimization 2024 Q2 Energy Engineering and Power Technology 2024 Q2 7.3 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Tregambi, Claudio Di Lauro, Francesca Solimene, Roberto Salatino, Piero Montagnaro, Fabio Romeo, Luis M.
