What is the difference between concentrating solar power (CSP) and thermal energy storage?

In contrast, concentrating solar power (CSP) plants which supplies thermal energy to the power cycle, obtain yields close to 100% through their combination with thermal energy storage (TES) systems [ 3, 4 ]. Furthermore, the capital cost of TES is lower than mechanical or chemical storage systems [ 5 ].

How much energy can a CSP plant store?

The newer CSP plants have significant storage capacity from 5 to 8.5 h using 2 tank-indirect storage configurations. Nevertheless, the fact that more than half of the plants do not allow for energy storage is a sign of a need to develop and integrate energy storage systems for this CSP configuration. 4.2. Dish/engine parabolic systems

Can concentrating solar power be integrated with thermal energy storage?

Concentrating solar power (CSP), when integrated with thermal energy storage (TES), can address both intermittency and storage needs by providing dispatchable renewable electricity.

How does a CSP power plant work?

Current operation of CSP plants is analogous to conventional thermal power plants, except for the use of solar radiation as a thermal energy source to produce electrical energy through an associated power cycle. A working fluid transfers the thermal energy, circulating between the solar field and the power block.

Should thermal energy storage be included in CSP plants?

Incorporating thermal energy storage into CSP plants boosts dispatchability without significantly impacting the levelized electricity costs compared to CSP plants without storage [17, 18]. This enhancement bolsters CSP's position as a valuable option for producing dispatchable renewable electricity.

Does CSP provide large-scale energy storage?

In addition to PSH and battery storage, CSP can provide large-scale energy storage, but the way CSP thermal storage characteristics differ from those of PSH and stationary batteries prevents direct comparison.
