Energy storage is one of the most significant challenges for a short-term deeper penetration of renewable energy sources. The Ca-Looping (CaL) process based upon the reversible carbonation/calcination of CaO is one of the most promising technologies for thermochemical energy storage (TCES).
Results show that full calcination of 10 kg/s can be achieved in a 51 m length and 2.5 m diameter downer reactor from an HTF releasing 17.2 MWth at temperatures higher than 1100°C.

Calcium-Looping (CaL) is considered as a promising process for thermochem. energy storage in the 3rd generation Concd. Solar Power plants using a supercrit. carbon dioxide power cycle. Here we propose, for the first time, a novel strategy to directly absorb solar energy using calcium-based composite thermochem. energy storage (TCES) materials.
Calcium looping (CaL) process, a thermochem. energy storage technique, probably offers a mid-term if not near-term soln. to the next generation Concd. Solar Power (CSP) plants featured with high temp. over 700°C.
Efficient integration of the Calcium-Looping process into Concd. Solar Power plants involves the endothermic calcination of CaCO3 in the solar receiver while the exothermic carbonation of CaO is carried out at high temp. under high CO2 partial pressure.
The optical absorption of the calcium-based materials plays a critical role in direct solar-thermal conversion for TCES. The key for directly capturing solar energy of Ca-based composites is to elaborately design such composites by altering their dielectric functions.
CO2 thermodn. cycles, calcium carbonate is a very promising candidate in storing energy for next-generation solar thermal power plants featured with high temp. over 700°C. However, CaCO3 particles are usually white with little absorption of sun light, inhibiting their application in efficient volumetric solar energy conversion systems.
