As a result, these types of storage are typically divided into two categories; storage of kinetic and potential energy, or storage of ''pressure energy''.
Kinetic Energy-Based Flywheel Energy Storage (FES): A flywheel is a rotating mechanical device that stores rotating energy. When a flywheel needs energy, it has a rotating mass in its core that is powered by an engine. The spinning force propels a tool that generates energy, like a slow-moving turbine. A flywheel is recharged to expand its speed again by using

Mechanical storage systems work on the basis of storing available and off-peak excessive electricity in the form of mechanical energy. Once the demand for electricity power overcome the available energy supply, the stored energy would be release to meet with the energy demand.
Operating principle of a gravity power type mechanical energy storage facility during charging and discharging [ 123] A flexible seal is required to build up pressure without allowing the water to mix. Since the piston moves very slowly, friction at the seal is assumed to be negligible.
Mechanical energy storage system especially FES can be deployed for the provision of short-duration power quality by supplying active power for very short duration in the range of 1–10 seconds. 7. Managing the high cost of mechanical energy storage systems
Energy storage using differences in the potential of liquid media has a long history. At least in the area of electric energy supply, it remains the most commonly used form of energy storage. This is particularly true of the storage technology discussed in the first part of this chapter: pumped-storage plants.
Hence, mechanical energy storage systems can be deployed as a solution to this problem by ensuring that electrical energy is stored during times of high generation and supplied in time of high demand. This work presents a thorough study of mechanical energy storage systems.
