“…However, it should be considered that the number of experimental research studies on the pilot-scale TCS-CaL for CSP plants (TRL 4–5) is still very limited. , Indeed, most of the works available in the literature are based on lab-scale studies, focused on the improvement of the process performance by enhancing the kinetics and multicyclic conversion of both natural , and synthetic Ca-based raw materials; ,, varying the process conditions (e.g., CO 2 partial pressure at reactors, temperature, particle size, etc. ). ,, Likewise, innovative process integration schemes have been also proposed, achieving thermal-to-electric efficiencies of up to 32–48%. , In this framework, the idea of integrating a CSP plant with a CaL-TCS system, although promising, is still in the research and development stage; the recently completed SOCRATCES project (Horizon 2020, Grant Agreement no. 727348) can be considered as a reference of the current state of the art.…”

Thermochemical energy storage (TCS) systems are receiving increasing research interest as a potential alternative to molten salts in concentrating solar power (CSP) plants. In this framework, alkaline-earth metal carbonates are very promising candidates since they can rely on wide availability, low cost, high volumetric density (>1 GJ m–3), relatively high operating temperatures (>800 °C), nontoxic and noncorrosive chemical nature, and no occurrence of any side reactions involving the production of undesired byproducts. Therefore, their reversible calcination/carbonation reaction with CO2 can be used to store/release energy in CSP plants. However, in spite of these promising features, the TCS research field is relatively new, and most of it is still limited to the lab-scale. Therefore, great research efforts are needed to bridge the gap from fundamental research to real-scale application and implementation of TCS-CSP systems. This manuscript reviews the state-of-the-art of carbonate-based systems for TCS in CSP plants. In particular, the literature has been analyzed in-depth, paying attention to (i) the materials development, with a focus on the solutions available to improve the durability of the materials (namely, the ability to withstand repeated carbonation/calcination cycles); and (ii) the design of the reactor configuration for both the solar-driven endothermic calcination and the exothermic carbonation reaction, focusing on the optimization of the reactor concept, based on the physicochemical properties and working temperatures of the reagents.

Recent contributions to thermochemical heat storage (TCHS) technology have been reviewed and have revealed that there are four main branches whose mastery could significantly contribute to the field. These are the control of the processes to store or release heat, a perfect understanding and designing of the materials used for each storage process, the good sizing of the reactor, and the mastery of the whole system connected to design an efficient system. The above-mentioned fields constitute a very complex area of investigation, and most of the works focus on one of the branches to deepen their research. For this purpose, significant contributions have been and continue to be made. However, the technology is still not mature, and, up to now, no definitive, efficient, autonomous, practical, and commercial TCHS device is available. This paper highlights several issues that impede the maturity of the technology. These are the limited number of research works dedicated to the topic, the simulation results that are too illusory and impossible to implement in real prototypes, the incomplete analysis of the proposed works (simulation works without experimentation or experimentations without prior simulation study), and the endless problem of heat and mass transfer limitation. This paper provides insights and recommendations to better analyze and solve the problems that still challenge the technology.

“…Also, some authors have studied the design of reactors [9] [28] and the management of the storage system [29]. Ortiz et al [21], Tesio et al [22] and Karasavvas et al [23] compared different power cycles aiming for the best performance when integrated with calcium looping TCES. All of them concluded that CO 2 power cycles provide the greatest results (supercritical CO 2 power block according to Tesio, and CO 2 closed Brayton cycle according to Ortiz and Karasavvas).…”
