High temperature heat storage system

What is high-temperature energy storage?

In high-temperature TES, energy is stored at temperatures ranging from 100°C to above 500°C. High-temperature technologies can be used for short- or long-term storage, similar to low-temperature technologies, and they can also be categorised as sensible, latent and thermochemical storage of heat and cooling (Table 6.4).

What is thermal energy storage?

Thermal energy storage can be used in concentrated solar power plants, waste heat recovery and conventional power plants to improve the thermal efficiency. Latent thermal energy storage systems using phase change materials are highly thought for such applications due to their high energy density as compared to their sensible heat counterparts.

What is latent heat thermal energy storage?

Latent heat thermal energy storage refers to the storage and recovery of the latent heat during the melting/solidification process of a phase change material (PCM). Among various PCMs, medium- and high-temperature candidates are attractive due to their high energy storage densities and the potentials in achieving high round trip efficiency.

What is high-temperature heat storage with liquid metals?

High-temperature heat storage with liquid metals can contribute to provide reliable industrial process heat >500°C from renewable (excess) electricity via power-to-heat processes. Liquid metals can also be used to efficiently transport high-temperature waste heat from high-temperature industrial processes to a heat storage medium for later use.

Are high temperature PCMs suitable for thermal storage?

In this review, however, the focus is to summarise latent heat thermal storage studies that use high temperature PCMs above 500 °C, if any, which are ideal for thermal storage integration into CSP plants and heat recovery.

What are liquid metal thermal energy storage systems?

Liquid metal thermal energy storage systems are capable of storing heat with a wide temperature range and have, thus, been investigated for liquid metal-based CSP systems 3, 4 and in the recent past also been proposed for industrial processes with high temperature process heat. 5
