About Us

Tharam-Thiran Green Energy Flow is committed to delivering affordable long-backup batteries for industries. Founded in 2020 in Tamil Nadu, India, our mission is to commercialize an affordable Sulfur-Iron-based flow battery that empowers industries to effectively utilize renewable energy. At Energy Flow, we are driven by our core value of fostering a positive team and family spirit, which inspires us to innovate continuously.

Our Solution

Why Energy Flow ?

Long-duration energy storage is crucial for accelerating the adoption of renewables. Flow batteries are emerging as a promising solution for meeting long-duration storage needs. A key advantage of our approach is the use of abundant and affordable electrolytes, making our Sulfur Iron Flow battery an attractive option for long-duration storage. We are currently commercializing this innovative technology.

Key Aspects

Long and Scalable BackupIn a fully redox flow battery, the backup duration can be increased simply by scaling up the electrolyte volume alone, without requiring any corresponding scaling of the battery stack.

SafetyFlow batteries are inherently safe and do not pose a risk of fire or thermal runaway.

Sustainable and AffordableOur product leverages sulfur and iron-based electrolytes, which are naturally abundant and contribute to a more sustainable energy storage solution. By avoiding the use of rare earth metals like lithium and vanadium, we reduce the environmental impact associated with extensive mining activities. Furthermore, our affordable electrolyte makes our flow battery one of the most economical options for applications requiring backup durations exceeding 20 hours.

Application

Our solution is designed for applications requiring more than 20 hours of energy storage. We primarily focus on industries that utilize off-grid renewable energy or renewable sources connected to weak grids. Our solution supports renewable energy adoption by overcoming the challenges of daily and seasonal intermittency.

Remote Telecommunication Infrastructures

We ensure uninterrupted power for critical communication infrastructure during outages, eliminating the need for diesel generators and contributing to your carbon credits. By providing stable and reliable renewable energy, we empower telecommunication companies to expand into remote areas and upgrade towers to the latest technologies.

Remote Mining Operations

We provide uninterrupted power for the critical mining equipment, significantly reducing fuel costs and carbon emissions by minimizing diesel generator usage. Our solution ensures reliable operation of essential safety systems, including ventilation, lighting, and emergency response equipment.

Technology

Energy FlowSulfur - Iron Flow Battery

A flow battery is an electrochemical energy storage device. Unlike conventional batteries, the electrolyte, which stores the energy, is kept outside the cell section in liquid form within a tank. The electrolyte is pumped into the cell section during charging or discharging processes. This design allows for the adjustment of the electrolyte volume to modify the battery system's backup duration.
Flow batteries, with their scalable backup capacity, offer a promising solution. Unlike vanadium-based flow batteries, which rely on expensive and rare materials, our sulfur-iron flow battery utilizes abundant and affordable electrolytes, making it an ideal choice for long-duration storage exceeding 20 hours.
