India’s Renewable Energy Secretary, Santosh Kumar Sarangi, announced that domestic researchers have successfully advanced sodium-ion battery technology to Technology Readiness Level 7 (TRL-7) and above.
Reaching TRL-7 signifies that a system prototype of the battery has been successfully demonstrated in an operational environment. According to the Secretary, technologies that achieve this maturity level are poised to move from pilot projects to commercial production within two to three years. This milestone is expected to drive the wider adoption of sodium-ion batteries, supporting expanding energy storage needs as India integrates a growing share of renewable energy.
This technological advancement comes at a critical time, as India is estimated to require around 411 GWh of energy storage by 2031–32. The Secretary noted that the country is progressing well toward this significant requirement and could potentially achieve it ahead of schedule.
transforms agricultural waste into advanced sodium-ion batteries and next-generation energy materials. Creating solutions that are sustainable, resilient, and built for generations to come.
We are preparing for tomorrow by reducing dependence on external sources and resources and building a truly indigenous, self-reliant energy ecosystem. By harnessing locally available materials, innovation, and technology, IndiEnergy is working toward an energy future that is independent, sustainable, and made in India.
