Electrical Energy Storage is a process of converting electrical energy into a form that can be stored for converting back to electrical energy when needed (McLarnon and Cairns, 1989; Ibrahim et al., 2008 ). In this section, a technical comparison between the different types of energy storage systems is carried out.
