Offgrid Energy Labs

Offgrid Energy Labs is a developer of patented zinc-bromide battery technology for long-duration energy storage, marketed under the ZincGel brand. The technology provides a safe, lithium-free, non-flammable storage solution using a water-based electrolyte that eliminates the fire risk associated with flammable battery chemistries. ZincGel batteries are designed to store renewable power for 6 to 16 hours without lithium, cobalt, nickel, or rare earths, offering full depth of discharge, high round-trip efficiency, and cost-efficient manufacturing through simpler processes than lithium-ion. The company modular system design targets renewable energy time-shifting, industrial decarbonization, and data center peak demand management, helping digital infrastructure reduce reliance on diesel backup. ZincGel resilient supply chains are manufactured through qualified partners, reducing dependence on single-site, capital-intensive gigafactories. Founded in 2018 and headquartered in Gurugram, India, Offgrid Energy Labs has raised approximately 5 million in a Series A round with investors including Ankur Capital, Action Potential Venture Capital, Shell E4, Archean Chemical Industries, and NB Ventures.
