India is making significant strides in renewable energy storage, a critical component in its journey towards a sustainable and energy-secure future. Recent advancements in battery technologies and strategic investments are positioning the country as a global leader in clean energy solutions.
Advancements in Battery Technology
One of the notable developments is the successful demonstration of sodium-ion battery storage technology. A collaboration between UK innovator LiNa Energy and Indian industry partner Tata Power, supported by the Innovating for Transport and Energy Systems (ITES), has led to the creation of a safer, low-cost alternative to traditional lithium-ion systems. This innovation was showcased at the India Energy Week 2025, marking a significant milestone in energy storage technology.
In parallel, researchers at the Indian Institute of Technology (IIT) Bombay have achieved a breakthrough in stabilizing sodium-ion batteries. By addressing challenges related to air and water instability in cathode materials, they have developed new materials exhibiting exceptional electrochemical cyclic stability. This advancement is expected to drive the development of cost-effective energy storage systems, essential for India's renewable energy goals.
Strategic Investments and Collaborations
India's commitment to renewable energy is further evidenced by substantial investments and international collaborations. Rio Tinto, a global mining giant, has signed a memorandum of understanding with India-based AMG Metals & Materials to explore the feasibility of developing a low-carbon aluminium project in India. The proposed project aims to utilize renewable energy sources such as wind and solar, supported by pumped hydro storage, to produce low-carbon metal for various industries.
Additionally, Apollo Green Energy Ltd has announced plans to invest ₹4,500 crore in Odisha to develop 1,000 megawatts of renewable energy projects. This initiative is expected to create 3,000 direct and indirect jobs, contributing significantly to India's green ambitions.
Government Initiatives and Future Outlook
The Indian government is actively promoting energy storage solutions to complement its renewable energy expansion. The Department of Science and Technology (DST) has been instrumental in advancing energy storage technologies, aiming to meet the country's target of 175 GW of renewable energy by 2022 and beyond.
Furthermore, the Central Electricity Authority (CEA) projects that India will require at least 41.7 GW/208 GWh of battery energy storage systems and 18.9 GW of pumped hydro storage by FY30. This underscores the critical role of energy storage in ensuring grid stability and continuous energy supply as the country scales up its renewable energy capacity.
Conclusion
India's recent breakthroughs in renewable energy storage technologies, coupled with strategic investments and government support, are setting the stage for a sustainable energy future. These developments not only enhance the country's energy security but also position India as a global leader in clean energy innovation.
