Tharam-Thiran Green Energy Flow is a cleantech company that specializes in affordable, long-duration energy storage solutions primarily for industrial applications. Founded in 2020 and headquartered in Tamil Nadu, India, the company focuses on creating commercially viable Sulfur-Iron-based flow battery technology. Tharam-Thiran’s mission is to enable industries to integrate renewable energy sources effectively through scalable, sustainable, and safe energy storage systems, addressing the intermittency challenges of renewables.
The company’s focus on utilizing abundant and low-cost materials like sulfur and iron positions it as a provider of an economic and environmentally conscious alternative to traditional battery chemistries. By doing so, Tharam-Thiran aims to reduce reliance on more expensive and geopolitically sensitive materials, contributing to a more resilient and sustainable energy future. Their approach to energy storage is designed to support the growing need for reliable backup power in various industrial and remote settings.
Battery Technology
Tharam-Thiran Green Energy Flow’s core innovation lies in its Sulfur-Iron (S-Fe) redox flow battery technology. This electrochemical energy storage device uses liquid electrolytes stored in external tanks, allowing for independent scaling of power and energy capacity. This design means that backup duration can be extended simply by increasing the electrolyte volume, without needing to physically expand the battery stack itself. The use of abundant and inexpensive sulfur and iron electrolytes distinguishes this technology from those that rely on rare or costly materials like lithium or vanadium.
A significant advantage of the S-Fe flow battery is its inherent safety; it poses no risk of fire or thermal runaway, which is a concern with some other battery types. This makes it a suitable solution for sensitive industrial environments and remote applications. Designed for long-duration backups exceeding 20 hours, Tharam-Thiran’s technology helps solve intermittency issues in renewable energy integration. The sustainable nature of the materials used also reduces environmental and mining impact. The company designs and manufactures its key components, including membranes and electrodes, in-house, ensuring quality control and supply chain reliability.
