Can calcium oxide based materials be used in concentrated solar power plants?

Sánchez Jiménez PE, Perejón A, Benítez Guerrero M, Valverde JM, Ortiz C, Pérez Maqueda LA (2019) High-performance and low-cost macroporous calcium oxide based materials for thermochemical energy storage in concentrated solar power plants.

How much energy is stored in calcium oxide?

If we assume that the heat capacity of the station is 10 MW, then we can theoretically obtain a chemical energy stored in calcium oxide of 4.3 MWh, which is equivalent to 13.6 tons CaO within one hour of solar brightness. The amount of water vapor resulting from the reaction that can be condensed into distilled water is 4.3 tons.

Can Cao/Ca(OH)2 be used in thermal energy storage?

The CaO/Ca(OH)2 storage system has received a lot of attention and research has been conducted with a view to its use in thermal energy storage in Concentrated Solar Power Plants (CSP).

What is Cao/Ca(OH)2 storage system?

Suggested method Most of the published research on the CaO/Ca(OH)2 storage system aims to use this system to store thermal energy in concentrated solar power plants, where it is necessary to recover the stored energy at the highest possible temperature in order to obtain a high yield in the turbines that generate electricity.

Is calcium looping a viable option for thermochemical energy storage?

Calcium looping-based processes are considered by many to be very effective and viable options for thermochemical energy storage, particularly for grid- and/or utility-scale applications [1, 2, 3, 4, 5, 6].

Is calcium-looping a promising energy conversion and storage technology?

This review focuses on the most recent developments of one of the most promising energy conversion and storage technologies – the calcium-looping. It includes the basics and barriers of calcium-looping beyond CO 2 capture and storage (CCS) and technological solutions to address the associated challenges from material to system.
