As countries progress towards a clean and sustainable future, Energy Storage Systems (ESS) can play a critical role in serving key energy end-uses in an energy secure and environmentally benign manner. The G20 could prove to be an important platform for furthering the agenda of ESS as it comprises of some of the largest energy consumers and energy technology holders in the world. Currently, developments in ESS in India are primarily based on import of batteries with little domestic manufacturing due to four major reasons – low mineral reserves, nascent battery manufacturing industry, lack of co-ordination among stakeholders, and high perceived risk. In meeting these challenges, there are a lot of lessons for India to learn from the development of BESS within the G20 countries such as legislations to encourage its greater uptake along with research and support towards up and coming BESS technologies. This paper analyses the current measures towards energy security and looks at the applicability of ESS for grid-connected renewable power and electric mobility. It also discusses the scope of engagement for India and potential ways of collaboration with other countries.
