Is calcium looping a good option for solar energy storage?

Solar thermochemical energy storage based on calcium looping (CaL) process is a promising technology for next-generation concentrated solar power (CSP) systems. However, conventional calcium carbonate (CaCO 3) pellets suffer from slow reaction kinetics, poor stability, and low solar absorptance.

What is calcium looping energy storage based on reversible chemical reaction?

Calcium looping (CaL) energy storage based on the reversible chemical reaction of CaO/CaCO 3 stands out from many TCHS systems due to its suitable operation temperature, low cost, and high energy storage density [ , , ].

Can calcium-looping be used for thermochemical energy storage in CSP plants?

For the proposed cases, the energy storage density, mainly dependent on CO2 pressure, CO 2 temperature and CaO conversion, varies between 0.2 and 0.9 GJ/m 3. Our study gives support to the potential benefits of using the Calcium-Looping process for thermochemical energy storage in CSP plants.

Is direct solar-driven thermochemical energy storage based on Ca-looping feasible?

Schematic diagram of direct solar-driven thermochemical energy storage based on Ca-Looping. Although direct solar-driven thermochemical energy storage has been demonstrated to be feasible via doping inert black substances and stabilizers, the reaction kinetics is very slow [ 45 ], which precludes achieving high power density TES.

How does calcium-based solar energy storage work?

High power density and highly stable calcium-based solar thermochemical energy storage is achieved simultaneously. The energy storage density is as high as 1455 kJ/kg with only a slight decay rate of 4.91% over 100 cycles. The energy storage rate is enhanced by 120% due to enhanced Ca 2+ diffusion and lower activation energy.

What is a thermochemical energy storage system?

This system is widely used in commercial buildings to enhance energy efficiency. They aid in lowering peak energy demand and can be combined with renewable energy sources for cost savings. Stadiums have integrated thermochemical energy storage systems to efficiently address peak cooling requirements.
