ABSTRACT
Energy storage has gained tremendous priority due to the profound changes in energy systems across the globe. Access to clean energy is a basic necessity to the people in developing and under-developing countries. The transition from conventional energy system to intermittent renewable energy sources raises concern about the production and consumption of power from these sources in an economical way. The location of the majority of renewable energy resources is resource-dependent, and proper transmission systems are necessary to tackle the constraint. Among the non-conventional energy resources, variability and predictability of the sources change considerably. Ensuring a continuous supply based on demand, development of grid structures and back-up systems is a major hurdle in power generation of these sources. Energy storage systems and the associated technologies contribute to adequate power balancing, grid stability, reliability, and integration of energy sources. This chapter addresses the different storage technologies with a focus on mechanical, electrochemical, chemical, electrical, and thermal storage systems.
