The article discusses the importance of energy storage in the context of the global Green Energy Revolution. It highlights various conventional methods of energy storage such as flywheels, batteries, compressed air, and pumped hydroelectricity. Moreover, it delves into the latest advancements in energy storage technologies like superconducting magnets, supercapacitors, photonic energy conversions, and hydrogen electrolysis, which are generating excitement among energy enthusiasts. With renewable energy generation expected to increase significantly by 2030, there is a pressing need for versatile, frugal, and sustainable energy storage solutions to ensure grid stability. The variable nature of renewable energy sources poses challenges to the national electricity transmission grid, necessitating efficient energy storage systems. Lead acid batteries are currently dominant in the Indian market due to their reliability for DC backup, despite facing challenges such as corrosion and environmental concerns. The article also underscores the importance of battery recycling for environmental sustainability. While lead acid batteries boast a high recycling rate, lithium-ion batteries face challenges in recycling and proper disposal, posing environmental risks. The management of battery disposal in India is governed by the Ministry of Environment, Forest and Climate Change (MoEFCC), emphasizing the need for collaboration between government and organizations to promote battery recycling and educate the public. Overall, the article advocates for the development of innovative energy storage solutions and policies to address the challenges of energy storage and ensure environmental sustainability in the future.
