Energy storage is an essential enabling technology in energy management. Increased number of population, more industrialisation trends and more electrical energy centric development forced to think about the future energy potential. In conventional ways of producing electricity, the main sources of energy are Coal, natural gas and petroleum oil. All these sources are carbon-based and store carbon as potential energy and release it when burned which causes greenhouse gas emission a major culprit in climate change and global warming. Australia’s reliance on coal-fired power makes it one of the world’s highest per-capita greenhouse gas emission rates. To meet the future electricity demand and to minimise the emission of greenhouse gases, renewable energy (RE) sources like wind, solar, hydro, tidal, biomass or geothermal are the alternative options to adopt and they are naturally replenished.
