Reduce fluctuation in energy consumption. Thermal Energy Storage Tank produces and stores the thermal energy in the form of chilled water during off-peak hour. During peak hour, the chilled water is pumped from the bottom of the storage tank and distributed to the facility, whilst the warmer water enters from the top of the tank hence smoothing

Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar collectors or waste heat from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months.
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 [4] and power generation. TES systems are used particularly in buildings and in industrial processes.

In the initial stage of heat storage, the heat transfer of PCM is mainly heat conduction, and rotation will produce a radial centrifugal force on liquid PCM. Therefore, the faster rotation speed makes high temperature liquid PCM more closely adhere to solid PCM and accelerate the melting of solid phase.

A tank thermal energy storage system generally consists of reinforced concrete or stainless-steel tanks as storage containers, with water serving as the heat storage medium. For the outside of the tank, extruded polystyrene (XPS) is used as an insulation material, and stainless steel is used for the interior to prevent water vapor from spreading.

In North America, one of the most common arrangements for a thermal storage tank is to install the unit between the heat source and distribution system as shown in Figure 1. Water from the heat source enters the tank''s upper-left side wall connection. Water headed for the distribution system exits from the upper-right side wall connection.

Tank Thermal Energy Storage (TTES) stores sensible heat in a medium, such as water, within a tank structure which is well insulated to minimise heat losses [30].
From a modelling standpoint, tank-exchanger assemblies can be categorised into two fundamental configurations as shown in Fig. 2.The exchanger may be situated on either the source or sink side. A source-side exchanger, see Fig. 2 a, is typically found in solar or heat pump systems, while a sink-side exchanger, see Fig. 2 b, is
Heat Storage. Heat storage refers to the ability of CSP power plants to store excess heat for later use, allowing for the generation of electricity on demand despite the fluctuating nature of solar energy resources. This storage capability enables the shifting of energy production to peak demand periods, increasing revenue potential.
