Battery energy storage (BES) will play a significant role in India’s energy transition. This presentation examines the fact that  the country has set an ambitious target for 30% Electric Vehicles (EVs)and  a target for 500 GWh Renewable Energy  (RE) by 2030. India Energy Storage Alliance (IESA) estimated a 600 GWh combined energy storage demand for EVs and stationary storage for India by 2030. In EV applications, lithium-ion batteries are more prevalent as they offer better performance characteristics such as energy and power density, cycle-life, and safety. For RE storage and grid applications, among the existing storage technologies are pumped hydro, thermal storage, compressed storage. BES is preferred due to advantages such as  compactness, rapid response, smaller gestation period, flexibility in installation. Lithium-ion chemistry is more prevalent within BES technologies. Flow batteries, sodium-based batteries, and zinc-based batteries are also emerging as they can be sized according to the requirements, have lesser performance degradation, and are economically viable.

Domestic battery manufacturing in India is gearing up significantly to cater to the domestic and global demand for Advanced Chemistry Cells (ACCs) batteries. IESA estimates that around 140 GWh and 550 GWh of ACC manufacturing capacity is expected by 2030 and 2035. To support the manufacturing capacity,  a cumulative requirement of 175 KT, 650 KT, and 2520 KT for battery materials has been estimated by 2025, 2030, and 2035. Materials like battery-grade copper, aluminium, manganese, graphite, iron, nickel, cobalt, lithium, vanadium, sodium, zinc have a huge demand in the emerging battery industry.
