The degree of conversion between CaO and CaCO 3 depends on the reaction temperature and CO 2 partial pressure. To determine the optimal reaction temperature and carbonation atmosphere, the equilibrium curve of the reversible reaction (Eq. (1)) was obtained by the Van''t Hoff equation and the standard molar generation

CaCO 3 /CaO thermochemical energy storage (TCES) system has a high heat storage density (1780 kJ/kg) along with high heat storage and release temperature (650–850 C), which can be applied to concentrated solar power (CSP) technology utilizing CO 2 Brayton cycles to improve power generation efficiency.
Thermochemical energy storage, for instance with Ca(OH) 2, offers high energy densities at low material costs and could therefore be a promising storage alternative for CSP-plants.Yet, due to the low thermal conductivity of the Ca(OH) 2 material large storage capacities operated in an indirectly heated fixed bed also require large

A close-loop CaLP-TCES process for solar energy storage was investigated. • Na 2 CO 3 doubled the energy storage capacity of the CaO-based materials. "850 C–900 C" was best for the Na 2 CO 3 doped CaO in the CaLP-TCES system. Improved CO 2 diffusion leads to the higher energy storage density of the Na + doped materials.

1. Introduction The consensus reached in the COP21 (21st Climate Change Conference Meeting) was to alleviate the natural greenhouse impact of the earth caused by the massive emission of anthropogenic CO 2 emissions, and limit the global surface temperature rise below 2.0 C [1].].
As shown in Fig. 10 a, the thermal energy storage density of CCi-CaO sharply decreased from 1.35 GJ/t in the 1st thermal energy storage cycle to 0.85 GJ/t in the 20th thermal energy storage cycle. Conversely, the composites deposited with inert stabilizer all present high thermal energy storage density and excellent stability.
