Rethinking Battery Chemistry: A Strategic Alternative to Lithium

Offgrid Energy Labs, a deep-tech energy storage startup based in India, is challenging lithium’s long-standing dominance in the battery market by developing and commercializing a zinc-bromine battery system called ZincGel. Amid volatile lithium supply chains, limited mineral access, and high costs, the startup offers a timely alternative for stationary energy storage.

ZincGel delivers 80–90% of the energy efficiency of lithium-ion batteries but offers lower levelized costs and longer service life. The technology also utilizes a proprietary water-based electrolyte, greatly minimizing fire risks, and boasts resilience under extreme temperature conditions, including operations at –10°C. With improved safety, affordability, and endurance, ZincGel positions itself as a strategic option for net-zero industries and off-grid energy applications.

The causal relationship is clear: the rising global dependence on lithium heavily sourced and refined in China creates systemic risk. Offgrid’s zinc-based approach directly mitigates this vulnerability by leveraging more abundant, safer, and regionally accessible materials.

Strategic Capital to Accelerate Commercialization

The $15 million Series A funding round, led by Archean Chemicals and joined by Ankur Capital, values Offgrid at approximately $58 million post-money. Archean now holds a 21% stake, a move aligned with its existing strengths in bromine production and supply chain management. This strategic alignment provides both material access and scale-up capabilities that are crucial for Offgrid’s next growth phase.

The funding will support the construction of a 10-megawatt-hour demonstration facility in the UK by Q1 2026, followed by commercialization and plans for an Indian gigafactory. Offgrid’s U.K. facility is designed to operate with a carbon footprint 50% lower than conventional lithium battery plants, thanks to simpler manufacturing processes and reduced material intensity.

While India remains a major target market, Offgrid chose the UK for its initial pilot due to Europe’s advanced battery manufacturing ecosystem, easier access to early customers, and the presence of two co-founders already based in the region.

Technology and Intellectual Property: A Differentiated Edge

Founded in 2018 at IIT Kanpur by Tejas Kusurkar, Brindan Tulachan, Rishi Srivastava, and Ankur Agarwal, Offgrid has spent its formative years building core intellectual property. To date, the company has secured more than 25 IP families and 50 assets across global markets, including the U.S., U.K., China, India, Australia, and Japan.

Compared to other zinc-bromine battery players such as EOS Energy Enterprises, Offgrid claims its proprietary electrolyte chemistry and carbon-based cathodes enable both fast charging and long-duration discharges (6–12 hours), while significantly lowering material costs by reducing the use of graphite.

These performance metrics when paired with flexible application tuning and long cycle life allow the ZincGel system to meet a variety of industrial energy storage needs that lithium batteries cannot serve as effectively.

Commercial and Global Traction: Positioning for Deployment

Offgrid’s early customer base includes notable names such as Shell and Tata Power, both of which are testing ZincGel for integration into peak-shaving, grid stability, and decentralized power scenarios. The startup is also in discussions with global utility players like Enel Group to tailor battery systems for specific European requirements.

Its early production has been manual, conducted in a lab in Noida, India, but with new capital and facilities, the firm is preparing to enter commercial-scale manufacturing. The flexibility of the technology also allows Offgrid to customize battery configurations based on end-user needs, expanding its applicability across industrial, renewable, and off-grid segments.

The startup’s business case rests on delivering the same (or better) performance at lower cost a value proposition that targets customers looking for both economic and environmental sustainability.

Offgrid Energy Labs’ zinc-bromine battery platform represents a decisive shift in energy storage innovation one that challenges the status quo of lithium-centric solutions. With robust IP, strategic investors, and clear market applications, the company is poised to become a major player in the global battery transition. As countries like India and the U.K. seek to scale renewable infrastructure without relying entirely on lithium, Offgrid’s ZincGel may offer a sustainable, cost-efficient alternative built for the next era of clean energy resilience.
