Tharam-Thiran Green Energy Flow Private Limited

Tharam-Thiran Green Energy Flow is a deep-tech startup based in Chennai, India, that specializes in the development of sulfur-iron redox flow batteries. Founded in 2020, the company aims to provide safe, scalable, and affordable long-duration energy storage solutions to address the challenge of renewable energy intermittency. Their technology is designed to decouple power and energy, offering an alternative to traditional, expensive, and rare-material-dependent batteries like those utilizing vanadium. By leveraging abundant materials, the company focuses on creating high-performance energy storage systems suitable for both grid-connected and off-grid applications.

The company's solutions are targeted at industries seeking to reduce reliance on fossil fuels, enhance energy security, and maintain power continuity, particularly in environments where grids may be weak or unreliable. Through engagement in programs like GDC’s I-NCUBATE, the team has refined its focus toward developing climate-resilient energy storage systems capable of operating in harsh environments, such as remote areas. The company has received backing from institutional investors and support from innovation ecosystems including IIT Madras, helping it advance its prototypes and commercialization efforts for industrial energy management.
