The Basic Principles of Energy Storage-Energy storage is a crucial technology that can capture and preserve energy for future use, Types of Energy Storage Systems Utilizes gravitational potential energy by pumping water to a higher elevation during low demand and releasing it to generate electricity during peak demand.
TES systems are divided into two categories: low temperature energy storage (LTES) system and high temperature energy storage (HTES) system, based on the operating temperature of the energy storage material in relation to the ambient temperature [17, 23]. LTES is made up of two components: aquiferous low-temperature TES (ALTES) and cryogenic

A typical thermal energy storage system is often operated in three steps: (1) charge when energy is in excess (and cheap), (2) storage when energy is stored with no demand and (3) discharge when energy is needed (and expensive). For example, a mixture of water, ice and steam is a pure substance, while a mixture of liquid air and gaseous air

Table 1 explains performance evaluation in some energy storage systems. From the table, it can be deduced that mechanical storage shows higher lifespan. Its rating in terms of power is also higher. The only downside of this type of energy storage system is the high capital cost involved with buying and installing the main components.

This method stores energy in the form of water, pumped from a lower elevation reservoir to a higher elevation. In pumped hydroelectric energy storage systems, water is pumped to a higher elevation and then released and gravity-fed through a turbine that generates electricity.
Water can be run through turbines from the upper reservoir to the lower one and hence produces electricity. But then water can be pumped back up to the storage area at the higher elevation, effectively recharging the system. In this case, it is also possible to use two-way turbines.
