CHENNAI: Deep-tech startup Meine Electric claims to have developed the world's first fast-charging iron-air battery system, marking a significant technical advancement for long-duration energy storage.

The technology, which features a proprietary fast charge long discharge capability allowing the battery to charge in 6 hours and discharge over 18 hours, has been independently validated by Customized Energy Solutions, a US-based global energy services and technology company and the parent organisation of the India Energy Storage Alliance.

"Traditional iron-air systems are restricted to multi-day cycles, making them largely incompatible with the intermittent nature of renewable energy generation. Furthermore, solar-heavy grids don't need a 100-hour battery. By engineering our system to capture a full charge within a tight 6-to-8-hour window, we are turning iron-air batteries from a sluggish backup chemistry into a foundational, daily-cycling asset," said Priyansh Mohan, co-founder-CEO, Meine Electric.

Founded in 2023 by him alongwith Stuti Kakkar, the Chennai-based Meine Electric is the first company in APAC, and the third player globally, pioneering iron-air long-duration energy storage.

"The energy industry prioritises lower costs and higher reliability, and iron-air technology is structurally positioned to deliver on both," stated Stuti Kakkar, co-founder-COO, Meine Electric.
