BESS Startup VFlowtech Secures USD 20.5 Million

VFlowTech, a leading provider of sustainable long-duration energy storage solutions, has announced a significant capital raise of $20.5 million to support its strategic expansion into India’s clean energy sector. the firm offers long-duration energy storage and AI-driven energy management.

The funding will enable VFlowTech to scale its existing 100 MWh manufacturing plant in India to a Gigafactory and supercharge the rollout of its unique Vanadium Redox Flow Batteries (VRFB) in India’s rapidly growing renewable energy market.

The round was led by Granite Asia, with strong backing from Antares Ventures, EDBI, MOL PLUS, PSA Ventures, and returning investors including İnci Holding, UntroD Capital, Pappas Capital, Wavemaker Partners, SEEDS Capital, and Entrepreneurs First.

The investment round reflects increasing investor confidence in vanadium redox flow battery (VRFB) technology as a critical part of efforts to stabilising renewable-heavy grids and its potential to accelerate decarbonisation in India. VFlowTech claims that its modular, scalable, and safe VRFB battery systems are tailored to meet increasing demand for resilient, scalable, and sustainable power infrastructure.

VFlowTech’s VRFB technology offers 25+ year life cycles, high safety, and deep discharge capability without degradation — pitching it as an alternative to lithium-based batteries for utility-scale applications, microgrids, and commercial and industrial (C&I) energy users.

Complementing VFlowTech’s long duration energy storage systems is an AI-driven cloud energy management platform designed to manage, monitor and optimise energy usage across distributed renewable assets and provide energy trading as well as ancillary services for the grid.

“India is at a tipping point in its clean energy journey. With this funding, we are not just bringing advanced energy storage technologies to market — we are shaping the future of sustainable energy infrastructure in the region.” said Dr. Avishek Kumar, Co-Founder and CEO of VFlowTech. “With our AI energy platform, we intend to build digital brains to India’s energy backbone, while scaling our local manufacturing capabilities and creating high-quality jobs in the country,” added Dr. Kumar.

The company intends to scale up hiring across engineering, research and operations talent in the country while it gets ready to deploy more indigenously manufactured BESS systems suited for India grid conditions. VFlowTech also intends to use the funds to advance vanadium recycling and create innovation around electrolyte manufacturing in India to build local supply chain efficiencies.

With several grid-scale and microgrid deployments already in place, VFlowTech is currently in advanced discussions with renewable energy developers and industrial customers in India to deploy up to 1 GWh of VRFB systems in the next few years.
