VFlowTech, a leading provider of sustainable long-duration energy storage solutions, has announced a significant capital raise of USD 20.5 million to support its strategic expansion into India’s clean energy sector and to further strengthen its ambitious goal of helping accelerate India’s transition to renewables with 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 the key to stabilising renewable-heavy grids and its potential to accelerate decarbonisation in India. With India’s energy market undergoing rapid reform and electrification surging across sectors, VFlowTech’s 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 — making it an ideal 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.
“India represents one of the most exciting opportunities for energy transition. With its ambitious renewable energy targets and increasing need for grid stability, coupled with the policy momentum, our long-duration storage and AI-integrated systems are a perfect fit for enabling a reliable, 24/7 clean power future,” said Anand Anupam, Chief Commercial Officer of VFlowTech.
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.
This investment marks a turning point not just for VFlowTech, but for how India can adopt sustainable energy storage at scale,” added Anupam. “We’re building long-term partnerships in India to demonstrate how clean, smart storage can power entire cities, industries, and states.”
According to the Ministry of New and Renewable Energy (MNRE), the total capacity for renewable energy installations has reached 220.10 GW, marking a record-breaking increase of 29.52 GW in the FY 2024-25. It highlights a remarkable milestone in achieving 500 GW of non-fossil fuel-based capacity by 2030, as part of its commitments under PM Narendra Modi’s ‘Panchamrit’ goals which is possible only by deploying more long duration energy storage like VFlowTech together with additional RE capacity.
