Mechanical energy storage can be added to many types of systems that use heat, water or air with compressors, turbines, and other machinery, providing an alternative to battery storage, and enabling clean power to be stored for days.
An in-depth understanding of the different types of mechanical energy storage, how they work, and their advantages and disadvantages can help users make informed choices for their specific energy storage needs.

Abstract This chapter considers energy stored in the form of mechanical kinetic and potential energy. This includes well-established pumped hydroelectric storage (pumped hydro) and flywheels as well as more recent concepts of gravity and buoyancy energy storage.
The chapter concludes with a description of classical and modern flywheel energy storage systems. This age-old technology is then compared with a new concept: mechanical stored energy exploiting both pumped storage and change in the potential energy of rocks or large boulders.
DEFINITION: The storage of energy by applying force to an appropriate medium to deliver acceleration, compression, or displacement (against gravity); the process can be reversed to recover the stored kinetic or potential energy.
Mechanical energy storage systems are those energy storage technologies that convert electrical energy to a form of storable energy flow (other than electricity) when charging to reclaim it for electricity production (or co- and tri-generation) over a discharging phase.
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.
Another theoretical mechanical stored energy concept is called the gravity power storage system. Unlike the hydraulic rock storage system described in Abschn. 9.3.2.1, the dimensions of the gravity power system are small. The storage principle is also slightly different, since it uses the same principle as the power tower system (Abschn. 9.3.2.3 ).
Mechanical energy storage operates through various physical principles that allow energy to be stored and converted back into usable power. For instance, pumped hydro systems function by converting electrical energy into gravitational potential energy.
Mechanical energy storage technology plays an important role in load regulation, energy conversion and stability improvement of power system. Mechanical energy storage mainly includes pumped storage, flywheel energy storage and compressed air energy storage.
Mechanical energy storage systems are very efficient in overcoming the intermittent aspect of renewable sources. Flywheel, pumped hydro and compressed air are investigated as mechanical energy storage. Parameters that affect the coupling of mechanical storage systems with solar and wind energies are studied.
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.
