development of new types of fluids that can operate at much higher temperatures than current systems (i.e., up to 425°C) and that are suitable both as heat-transfer fluids in the solar field, as well as thermal energy storage (TES) media in the storage system [1]. The advantage of TES is that it will
3 · TES works on utilizing storage and release of thermal energy by using heat transfer fluids (HTF) to drive a power cycle for electricity generation [6]. TES systems are categorized into sensible, latent, and thermochemical heat storage methods based on their underlying mechanisms of energy storage and release [ 7 ].
Further, Zhang et al. [8] treated the thermal energy storage as a simplified direct heat exchanger and assumed the energy stored was fully recovered.

Particle-based thermal energy storage systems are one promising technology by storing excess electricity or heat as sensible thermal energy in inexpensive, solid, inert particles. When the system needs to discharge, the stored particles transfer their thermal energy to a working fluid (e.g., air) which drives a traditional air-Brayton
Solar thermal energy in this system is stored in the same fluid used to collect it. The fluid is stored in two tanks—one at high temperature and the other at low temperature. Fluid from the low-temperature tank flows
8.5. Thermal Energy Storage. Different types of fluids are commonly used for storing thermal energy from concentrating solar power (CSP) facilities. CSP plants typically use two types of fluids: (1) heat-transfer fluid to transfer the thermal energy from the solar collectors through the pipes to the steam generator or storage, and (2) storage

E v = latent volumetric energy storage. E v * = volumetric energy storage within 20 °C of T m (T m ± 10 °C). This value accounts for the small but significant additional energy stored in the form of sensible heat. We have assumed a specific heat capacity (C p) value of 1.5 J mol −1 K −1 for the calculation because of the absence of data in the solid and liquid state.
Storage of hot water, underground thermal energy storage [33], and rock-filled storage are examples of thermal energy storage systems.

The different kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. Sensible heat storage (SHS) is the most straightforward method. It simply means the temperature of some medium is either increased or decreased. This type of storage is the most commerciall

Sensible heat storage (SHS) implies storing thermal energy in a storage media by increasing its temperature and extracting heat using heat transfer fluid (HTF). SHS is widely discussed in the literature, especially in terms of storage material and numerous large-scale projects [ 27, 28 ].
It has been established that the development of a storage option and increasing the operating temperature for parabolic trough electric systems can significantly reduce the levelized electricity cost compared to the current state of the art.
