High temperature energy storage solar energy is environmentally friendly

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).

Is high temperature solar thermal energy storage based on chemical reactions beneficial?

This paper presents the state of the art on high temperature (573–1273 K) solar thermal energy storage based on chemical reactions, which seems to be the most advantageous one for long-term storage. The paper summarizes the numerical, experimental and technological studies done so far.

How can solar thermal energy be stored long-term?

Thermochemical TES systems appear to be the most promising way to store solar thermal energy during a long-term period. Indeed, both storage period and transport distance are theoretically unlimited because there is no loss of thermal energy during storage as products can be stored at ambient temperature.

What is thermal energy storage (TES)?

One solution is to develop thermal energy storage (TES) systems, which will store heat during the sunshine periods and release it during the periods of weak or no solar irradiation. A CSP equipped with a TES system would continuously supply electricity.

Why is high-temperature storage important?

High-temperature storage offers similar benefits to low-temperature storage (e.g. providing flexibility and lowering costs). However, high-temperature storage is especially useful for smart electrification of heating and cooling in industry, given that many industrial processes either require high temperatures or produce high-temperature heat.

What is a sensible heat storage system?

Sensible heat storage systems are the most mature technologies. They have been and are still being used in industrial plants, most notably in Spain, with the PS10 and PS20 projects (2007 and 2009) or the Andasol 1 and 2 plants (2008), but also in the USA, e.g. with Solar One (1982) .
