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.

The energy storage density of the phase-change material is ultimately reflected in its enthalpy value, with higher enthalpy values indicating greater energy storage density. The powder obtained after mechanical strength testing was used to directly record the curve of heat flow as a function of time using a differential scanning calorimeter (DSC).

Energy Storage explains the underlying scientific and engineering fundamentals of all major energy storage methods. These include the storage of energy as heat, in phase transitions and reversible chemical reactions, and in organic fuels and hydrogen, as well as in mechanical, electrostatic and magnetic systems.

Abstract. Storage of energy is necessary in many applications because of the following needs: (a) Energy may be available when it is not needed, and conversely energy may be needed when it is not available. (b) Quality of the required energy may not meet the characteristics of the available energy, such as when an intermittent energy supply is
