India's First Industrial-Scale Vanadium Redox Flow Battery Project to Deliver 100 MWh of Grid Storage

## India's First Industrial-Scale Flow Battery Project Signals Shift in Energy Storage Landscape Indian energy storage firm Delectrik Systems has announced it will deploy the country's first industrial-scale vanadium redox flow battery (VRFB) project, with a capacity of 100 MWh, according to a PR Newswire release dated 21 July 2026. The company secured the contract in partnership with Bondada Engineering following a competitive tender process. The project marks a significant milestone for India's energy storage sector, introducing a battery technology long favoured in applications requiring long-duration, high-cycle storage — characteristics particularly relevant to port electrification, shore power systems, and maritime logistics hubs that demand reliable, large-scale energy buffers. Vanadium redox flow batteries differ from conventional lithium-ion systems in that they store energy in liquid electrolyte solutions held in external tanks, allowing capacity to be scaled independently of power output. This architecture offers advantages in safety, longevity, and deep-discharge capability, making the technology an increasingly attractive option for critical infrastructure operators, including those in the maritime and port sectors. For India's rapidly expanding port network — which includes major facilities at Mumbai, Chennai, Mundra, and Visakhapatnam — the commercial viability of large-scale flow battery systems could accelerate the adoption of shore-to-ship power, reduce diesel dependency in port operations, and support the integration of renewable energy sources such as solar and wind into port energy grids. The Gurugram-based firm's success in this tender positions Delectrik Systems as a key player in India's broader push toward energy transition, aligned with national targets to decarbonise heavy industry and infrastructure. The collaboration with Bondada Engineering, an established infrastructure and engineering contractor, suggests the project is backed by significant execution capability. While the specific deployment site has not been detailed in the announcement, the scale of the installation — 100 MWh — places it firmly in the category of utility and industrial-grade storage, comparable to projects seen in European and East Asian port modernisation programmes. As the maritime industry globally faces mounting pressure to reduce emissions and transition to cleaner energy sources, developments in grid-scale storage technology onshore will play a critical enabling role in supporting electrified port operations and the broader decarbonisation of supply chains.
