Hustler Words – Offgrid Energy Labs, an Indian deep-tech startup, has secured $15 million in Series A funding to revolutionize energy storage. Their innovative ZincGel battery technology, developed at IIT Kanpur, offers a compelling alternative to lithium-ion batteries, addressing critical supply chain vulnerabilities and cost concerns. This breakthrough could reshape the global energy landscape.
Lithium’s dominance in battery technology is facing increasing challenges. Volatile supply chains, short lifespans, and environmental concerns are prompting a search for alternatives. Offgrid Energy Labs’ ZincGel technology, boasting 80-90% of the energy efficiency of lithium-ion batteries at a significantly lower cost, presents a viable solution. This is particularly crucial for India, which aims to drastically increase its renewable energy capacity by 2030, a goal hampered by China’s control over the lithium market.
The $15 million Series A round, led by Archean Chemicals and Ankur Capital, will fuel the construction of a 10-megawatt-hour demonstration facility in the UK, slated for completion in Q1 2026. Commercialization will follow, with a gigafactory in India planned as the next step. This strategic move leverages the UK’s established battery manufacturing ecosystem while keeping India firmly in sight as a key market.

Co-founder and CEO Tejas Kusurkar emphasizes the importance of financial viability alongside technological innovation. Unlike previous alternative battery technologies that failed due to high costs, ZincGel’s competitive pricing makes it a truly disruptive force. The technology, protected by over 50 intellectual property assets globally, utilizes a zinc-bromide chemistry with a proprietary water-based electrolyte, resulting in enhanced safety and a longer lifespan (twice that of a typical lithium-ion battery). The use of a carbon-based cathode further enhances fast charging and discharging capabilities.
Early adopters like Shell and Tata Power are already testing ZincGel, with discussions underway with major European players such as Enel Group. The technology’s adaptability allows for optimization based on specific applications, ensuring performance even in extreme temperatures. The UK facility will boast a 50% lower carbon footprint than a typical lithium-ion gigafactory, reflecting Offgrid’s commitment to sustainability. With a post-money valuation of approximately $58 million, Offgrid Energy Labs is poised to become a major player in the global energy storage market. The company’s success hinges on its ability to deliver on its ambitious plans, but the potential for disruption is undeniable.
