Dr Rahul Walawalkar, founder and executive director of the India Energy Storage Alliance (IESA), on why his organisation is excited by the promises of the Modi government, how he hopes the decade between 2015 and 2025 will be one of “energy infrastructure transformation” for the country and the role energy storage and microgrids might play in that transition.

The US Department of Energy’s Sunshot initiative has announced US$15 million in funding to aid the integration of solar into the electrical grid infrastructure using energy storage systems.

The developing economies of the world are largely located in geographical regions that have abundant renewable energy resources, be they solar, wind, hydro or in some cases geothermal, yet paradoxically at the individual and rural community level, access to energy is often a very real issue. Establishing a continuous chain of temperature controlled cold environments from the point of harvest to the marketplace and on into the home, a ‘cold chain’, is what is required in order to avoid produce spoilage and to connect farmers with higher value market options in distant urban centres or overseas.

India looks to be the latest country to examine installing energy storage at the top level, with the Power Grid Corporation of India (PGCIL) actively seeking demonstration projects and the country’s Ministry of New and Renewable Energy (MNRE) inviting comments from stakeholders ahead of similar plans.

Energy storage has been touted as the enabler of high levels of intermittent renewables in the electricity system – the silver bullet or Holy Grail for solar and wind. A key attribute for the technology’s deployment will be scalability, writes Melissa Lott.
