Thermal energy storage (TES) is utilized predominantly in structures and modern cycles. It includes putting away abundance energy, commonly surplus energy from inexhaustible sources, or waste hotness to be utilized later for warming, cooling, or force age. Fluids like water or strong material - like sand or shakes can store nuclear power.

Apart from the rotating flywheel, the other main components of a flywheel storage system are the rotor bearings and the power interface as illustrated in Fig. 1 [5].The flywheel can be either low speed, with operating speeds up to 6000 rpm, or high-speed with operating speeds up to 50,000 rpm [2].Low speed flywheels are usually made of steel
The most important characteristics are power, stored energy, and response time. If a technology cannot provide all of these characteristics, it is not suited to the application.

Also, cost drawbacks of these technologies include high capital costs to install PHES and additional costs throughout the project''s lifetime resulting from the low efficiency of CAES. 6. Conclusions. The aim of this review was to determine well rounded energy storage technologies for use in industrial DSM.
For chilled water TES, the storage tank is typically the single largest cost. The installed cost for chilled water tanks typically ranges from $100 to $200 per ton-hour,12 which corresponds to $0.97 to $1.95 per gallon based on a 14°F temperature difference (unit costs can be lower for exceptionally large tanks).
Thermal energy can be stored by simply changing the temperature of a material to higher level for heat storage or to lower level for cold storage. The amount of the stored energy can be calculated as the product of the specific heat capacity, the mass of the used material and the temperature difference.
