Currently, the most common seasonal thermal energy storage methods are sensible heat storage, latent heat storage (phase change heat storage), and thermochemical heat storage. The three''s most mature and advanced technology is sensible heat storage, which has been successfully demonstrated on a large scale in
ATES cold storage systems have a shorter payback period compared to the heat storage ones because the stored cold can be employed directly with no heat pump. The life span of ATES systems is reported to be from 25 years ( Hartog et al., 2013 ) to 30–50 years ( Bloemendal et al., 2014 ).
The technology for storing thermal energy as sensible heat, latent heat, or thermochemical energy has greatly evolved in recent years, and it is expected to grow up to about 10.1 billion US dollars by 2027. A thermal energy storage (TES) system can significantly improve industrial energy efficiency and eliminate the need for additional
TES systems based on sensible heat storage offer a storage capacity ranging from 10 to 50 kWh/t and storage efficiencies between 50 and 90%, depending on the specific heat of the storage medium and thermal insulation technologies. PCMs can offer higher storage capacity and storage efficiencies from 75 to 90%.
Sensible heat storage (SHS) is by far the most common method for heat storage [8]. It is the simplest and easiest form of heat storage technology [12] . Sensible heat is the heat exchanged by a system that does not change its phase but changes the temperature of a storage medium.
3.3 Sensible Heat Thermal Energy Storage. Sensible heat storage is achieved by increasing ( heating) or decreasing ( cooling) the temperature of the storage medium. A typical cycle of sensible heat thermal energy storage (SHTES) system involves sensible heating and cooling processes as given in Fig. 3.3.
Although there are different alternatives, such as latent, thermochemical, or solid sensible heat storage [6–8], the most common TES materials are molten salts, which are classified as sensible heat storage [9]. Sensible storage implies that increasing the temperature of a substance increases its energy content; when the material is cooled

Water, which is abundant, non-toxic and cheap, is the most common liquid sensible heat storage medium (Gracia and Cabeza, 2015). It can be used up to 90 °C operation conditions ( Hasnain, 1998 ). Mineral oil, molten salts, liquid metals and alloys are also known as liquid STESMs ( Alva et al., 2017 ).
Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and industrial processes. In these applications, approximately half of the
Paraffin Waxes: Common in residential and commercial heating and cooling applications due to their moderate temperature range and high latent heat capacity. Salt Hydrates: Effective for higher temperature storage, used in industrial processes. 3. Thermochemical Storage. Thermochemical storage systems involve chemical reactions
For sensible heat storage, typical temperature difference is usually in the range of 5–10 °C. Temperature scale for space heating and domestic hot water production is usually at the operating range of 25–80 °C. One of the common applications is the solar hot water tank, as shown in Fig. 3.

The heat source is usually a renewable resource such as the sun, and the efficiency of high-temperature sensitive heat storage systems is increased with sensible heat storage materials. At temperatures above 100°C, the heat storage material may be oil
Sensible heat storage is thermal energy storage in a heat storage medium whose temperature changes as a function of heat addition or removal.

Oils and organic phase change materials are the most common classes of sensible heat and latent heat storage materials, respectively. In addition, the organic phase change materials utilized in the cookers had phase change temperatures of less than 120 °C, which were so low that the stored latent heats were not effectively utilized in the
Sensible heat storage is the most common, simple, low-cost and longstanding method for storing energy []. In sensible heat storage systems, no phase change or chemical reaction occurs. The only effect of storing or releasing energy is the increase or decrease of the temperature of the storage medium [ 2 ]; put aside minor

Sensible heat storage [7]: stores heat in a substance with a high heat capacity, such as water or rock, which can be heated and cooled as needed. Thermal Energy Storage Tanks [ 8 ]: stores thermal energy in a reservoir of hot fluid, such as water or molten salt, which can be used for heating or power generation as needed.
For two-phase heat carriers, sensible-heat storage systems have a low energy efficiency or large exergy due to the large temperature gradients between the storage media and HTF. In a latent-heat storage system, both the PCM and the heat carrier undergo a phase change at about the same temperature.
Solar thermal energy can be stored at extremely high temperatures using molten salt. Concentrated solar power (CSP) is used to heat the salt, which melts at 131 °C, to a blistering 566 °C when it is sent to a specially insulated tank to be stored. The thermal energy can be stored here for up to a week. Whereas most sensible thermal storage
For instance, thermal energy storage can be subdivided into three categories: sensible heat storage (Q S,stor), latent heat storage (Q Lstor), and sorption heat storage (Q SP,stor).
