en.Wedoany.com Reported - Indian battery technology company Offgrid Energy Labs has commissioned its first overseas manufacturing facility in Hook, Hampshire, UK, marking the start of commercial production of its proprietary ZincGel long-duration energy storage batteries outside India.

The new facility is equipped with a 10 MWh pilot production line and serves as Offgrid Energy Labs' first overseas manufacturing base. The primary goal of the factory is to validate the commercial viability of its zinc-bromine battery technology while laying the foundation for future large-scale manufacturing targeting the international energy storage market.

According to the company, the Hook factory is the first manufacturing unit in the UK dedicated to producing ZincGel batteries. The facility will demonstrate the commercial value of its long-duration energy storage platform through pilot-scale production. This expansion comes amid increasing global investment in energy storage systems and growing demand for grid-scale storage driven by renewable energy deployment. In India, the Central Electricity Authority estimates that the country will require over 411 GWh of energy storage capacity by 2031-32, with battery energy storage systems accounting for more than 236 GWh, highlighting the growing need for advanced energy storage technologies.

Offgrid Energy Labs' ZincGel technology, developed within India's deep science and innovation ecosystem, is based on zinc-bromine battery chemistry and is primarily applied in stationary energy storage. The company states that these batteries are non-flammable, eliminating the risk of thermal runaway—a key safety concern with traditional lithium-ion systems. The technology is designed to achieve 100% daily depth of discharge over a storage duration of 6 to 16 hours, with a service life of up to 20 years. These batteries are suitable for applications such as renewable energy integration, grid balancing, industrial backup power, microgrids, and peak demand management.

Offgrid Energy Labs co-founder Rishi Srivastava commented that the UK factory marks a significant milestone in bringing India's deep technology innovations to the international market. He stated that the manufacturing unit will enhance the company's ability to serve global customers while contributing to energy security, supply chain resilience, and the transition to low-carbon power systems. Co-founder Tejas Kusurkar noted that the global energy transition requires multiple battery chemistries to meet diverse storage needs, and that zinc-bromine technology is well-suited for stationary storage due to its long lifespan, deep discharge capability, enhanced safety performance, and abundant raw material availability.
