Concentrated solar power (CSP) integrated with calcium looping (CaL) technology has garnered significant interest as a solution to mitigate the issue of intermittency in solar power production.
A new expression for the energy density in gas-solid thermochemical systems is proposed. The Calcium-Looping process is a promising thermochemical energy storage method based on the multicycle calcination-carbonation of CaCO3-CaO to be used in concentrated solar power plants.
Conclusions This work analyzes the multicycle activity of CaO derived from diverse natural CaCO 3 minerals (limestone, chalk and marble) at optimum Calcium-Looping conditions for the thermochemical storage of energy in Concentrated Solar Power plants.
Multicycle CaO conversion depends on process conditions and CaO precursor. Process equipment well-known in the cement industry, excepting solar calciners. Energy storage based on thermochemical systems is gaining momentum as a potential alternative to molten salts in Concentrating Solar Power (CSP) plants.
CC-BY 4.0 . Long-term storage capability is often claimed as one of the distinct advantages of the calcium looping process as a potential thermochemical energy storage system for integration into solar power plants. However, the influence of storage conditions on the looping performance has seldom been evaluated experimentally.
CaO conversion plays a fundamental role in the CaL process efficiency . According to Prieto et al. , the CaL system could be a viable option to be integrated in CSP plants though the authors warn that CaO deactivation can be a drawback.
The CaL process is a promising TCES technology to be used in CSP plants [, , , , ]. Fig. 1 shows a conceptual scheme of the CaL process integration. After heat recovery, the CaO and CO 2 streams produced in the solar calciner are stored for their use afterwards as a function of energy demand.
