Rahman et al. [3] presented technological, economic, and environmental assessments of mechanical, electrochemical, chemical, and thermal energy storage
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
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.

Mechanical energy storage systems take advantage of kinetic or gravitational forces to store inputted energy. While the physics of mechanical systems are often quite simple (e.g. spin a flywheel or lift weights up a hill), the technologies that enable the efficient and effective use of these forces are particularly advanced.

Flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in two hours. Much of the friction responsible for this energy loss results from the flywheel changing orientation due to the rotation of the earth (an effect similar to that shown by a Foucault pendulum). This change in orientation is resisted by the

Mechanical energy storage systems can be used in the grid to balance peak periods and to provide ancillary services including frequency, primary and voltage control to the power grid. The main technologies include pumped hydro energy storage (PES), flywheels, compressed air energy storage (CAES), and liquid air energy storage (LAES).
As of 2018, the energy storage system is still gradually increasing, with a total installed grid capacity of 175 823 MW [ 30 ]. The pumped hydro storage systems were 169557 GW, and this was nearly 96% of the installed energy storage capacity worldwide. All others combined increased approximately by 4%.
Among the different mechanical energy storage systems, the flywheel energy storage system (FESS) is considered suitable for commercial applications. An FESS, shown in Figure 1, is a spinning mass, composite or steel, secured within a vessel with very low ambient pressure.

Abstract. This invention relates to a mechanical energy storage system, incorporating upper and lower reservoirs supported in a rigid frame. Metal balls are initially stored in the upper reservoir, a form of storage with potential energy that can be converted to kinetic energy. The balls are selectively released from the upper reservoir.
Abstract. A flywheel energy storage (FES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems that is most appropriate for small- and medium-scale uses and shorter period applications. In an FES system, the surplus electricity is stored in a high rotational velocity disk-shaped flywheel.
