Sthyr Energy is a deep-tech startup founded by IIT Madras researchers Gunjan Kapadia, Akhil Kongara, and Muhammed Hamdan that is commercializing next-generation zinc-air battery technology. Its architecture employs non-flammable, water-based electrolytes and separates energy and power components, allowing safe, flexible, and modular installations. The systems are intended for grid operators, renewable energy farms, microgrids in rural or remote areas, and defense or island communities currently dependent on diesel. By offering a levelized cost of energy (LCOE) that it claims is competitive for long-duration storage, Sthyr positions its solution as an alternative to lithium-ion batteries. The company plans to channel fresh capital into scaling R&D, building prototypes, and conducting pilot deployments. As India accelerates renewable energy adoption, Sthyr aims to capture demand for efficient, scalable storage solutions. No revenue, user, or deployment metrics were disclosed in the article.
