6.1 Introduction. There are two basic types of energy storage that result from the application of forces upon materials systems. One of these involves changes in potential energy, and the other involves changes in the motion of mass, and thus kinetic energy. This chapter focuses upon the major types of potential energy and kinetic energy storage.

There are three main types of MESSs, as shown in Fig. 1; flywheel energy storage system (FESS) [18], pumped hydro energy storage (PHES) [19] and compressed air energy storage (CAES) [20]. MESSs can be found in some other different forms such as liquid-piston, gravity and mechanical springs.
General. Energy is a scalar quantity and the mechanical energy of a system is the sum of the potential energy (which is measured by the position of the parts of the system) and the kinetic energy (which is also called the energy of motion): [1] [2] The potential energy, U, depends on the position of an object subjected to gravity or some other ...
