Delectrik builds flow batteries that store renewable power for far longer than its counterparts

Delectrik Systems, a company based in Gurugram, Haryana, specializes in building vanadium redox flow batteries for commercial, industrial, and utility-scale energy storage. Founded by Vishal Mittal, the company's technology uses two tanks of liquid electrolyte to store and release energy, which eliminates wear and tear on traditional solid electrodes found in lithium-ion batteries.

Unlike lithium-ion batteries, this flow battery design can last for decades without significant degradation, making it ideal for grid-scale energy storage where space is less of a concern than replacement cycles.

The key advantage of Delectrik's flow batteries is their use of a non-containerised architecture, which involves tanks, pumps, and stacks built directly into a site rather than bulky shipping containers. This design is particularly beneficial for installations requiring tens of megawatt hours of storage. Additionally, the vanadium electrolyte used in Delectrik's batteries is water-based and non-flammable, presenting a safer alternative to lithium-ion batteries that are prone to thermal runaway and fire hazards.

This technology also allows for fully discharging the battery without damage, unlike lithium systems that suffer from performance loss when discharged completely.

Looking ahead, Delectrik is strategically positioning itself with two subsidiaries: Delectrik Resources, focused on vanadium oxide production and eventual vanadium asset development, and Delectrik Esaas, aiming to offer storage as a service to various customers. The demand for vanadium is a challenge, as its supply is concentrated worldwide, but Delectrik's ability to source and process its own material provides a competitive edge over competitors relying on external suppliers.

As India's renewable energy capacity, particularly solar, grows faster than storage capacity, Delectrik's long-duration energy storage solutions address the critical mismatch between energy production and consumption, paving the way for a more reliable and efficient grid.
