A new study by Ember and TERI indicates that India can avoid new coal power capacity after 2030 if battery storage costs fall by 15% annually, enabling greater reliance on renewable energy. Currently, coal generates nearly 75% of India's electricity, but to achieve net-zero emissions by 2070, the country must reduce coal dependence and enhance energy storage systems. If battery storage costs continue to decline at the current rate of 7% per year, coal generation is expected to plateau until 2032, but additional coal capacity may still be needed during non-solar hours. The report highlights that if costs decrease significantly, renewable energy could meet 83% of daytime electricity demand. Furthermore, Indian electric vehicle manufacturer Ola Electric aims to reduce EV costs by 25-30% with its new indigenous 4680 Bharat battery cell, which promises better energy density and efficiency. This shift towards more affordable battery technology is crucial for India's transition to a sustainable energy system.
