Thermal energy storage systems are key components of concentrating solar power plants in order to offer energy dispatchability to adapt the electricity power production to the curve demand. This paper presents a review of the current commercial thermal energy storage systems used in solar thermal power plants: steam accumulators and molten salts.
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 ].
Solar thermal energy storage has the potential to significantly increase the operating flexibility of solar power. TES allows solar power plant operators to adjust electricity production to match system demand, enabling the sale of electricity during peak demand periods and boosting plant revenues.
In that context, thermal energy storage technology has become an essential part of CSP systems, as it can be seen in Fig. 13, and has been highlighted over this review. Despite the total installed cost for CSP plants with TES tends to be higher than those without, storage also allows higher capacity factors.
Concentrated solar thermal power is a global-scale technology that has the capacity to satisfy the energy and development needs of the world without destroying it. It is particularly suitable for regions with high direct solar radiation, such as the desert regions of India.
CSP plants with thermal energy storage (TES) can overcome the intermittency of solar and other renewables, enabling dispatchable power production independent of fossil fuels and associated CO 2 emissions. Worldwide, much has been done over the past several decades to develop and validate what are now viewed as “conventional” CSP-TES solutions.
