摘要：
The integration systems between CaO/CaCO3 energy storage and concentrated solar power(CSP) plant, as well as the energy storage performance of CaO-based materials proposed in recent years were reviewed. The CaO/CaCO3 energy storage system coupled with closed Brayton cycle is an appropriate integration system, and the overall plant efficiency of this system is up to 46%. The main drawback of CaO/CaCO3 energy storage is the rapid decay in energy storage performance of general CaO-based material with the number of cycles. Moreover, the energy storage condition has a significant effect on the energy storage performance of CaO-based material. Doping inert supports or catalysts can improve the cyclic stability and energy storage performance of CaO-based material. Additionally, the advantages and challenges faced for CaO/CaCO3 energy storage were analyzed, and the direction towards which future works should be headed was discussed. © 2021, Central South University Press.
