• VFlowTech raises $20.5M to scale its Vanadium Redox Flow Battery (VRFB) tech and expand its India facility into a Gigafactory for long-duration energy storage.

• Focus on India’s renewable transition includes deploying AI-powered energy platforms and 1 GWh of VRFB systems, supporting grid stability and 24/7 clean power.

• Funds to boost domestic R&D and jobs, with plans for local vanadium recycling, electrolyte innovation, and large-scale deployment across utility and industrial sectors.


VFlowTech, a startup offering sustainable long-duration energy storage solutions, has secured $20.5 million in funding to fuel its strategic growth in India's clean energy market and further enhance its ambitious mission of aiding India's transition to renewables with long-duration energy storage and AI-based energy management.

The round was anchored by Granite Asia, with strong support from Antares Ventures, EDBI, MOL PLUS, PSA Ventures, and repeat investors such as İnci Holding, UntroD Capital, Pappas Capital, Wavemaker Partners, SEEDS Capital, and Entrepreneurs First.

The company stated that the new round of funding will allow it to expand its current 100 MWh production facility in India into a Gigafactory and accelerate the deployment of its patented Vanadium Redox Flow Batteries (VRFB) into India's fast-expanding renewable energy sector.

As India's energy sector is rapidly transforming and electrification is growing across industries, VFlowTech stated that its scalable, modular, and secure VRFB battery systems are designed to address growing demand for robust, scalable, and sustainable power infrastructure.

The company asserts that its VRFB technology supports 25+ year life cycles, high safety, and deep discharge capability without any degradation, and it claims this makes the technology a perfect substitute for lithium-based batteries in utility-scale, microgrid, and commercial and industrial (C&I) energy consumers.

Coupled with VFlowTech's long-duration energy storage systems is a cloud energy management platform powered by AI that can manage, monitor and optimize energy consumption across distributed renewable assets and offer energy trading and ancillary services to the grid.
Purpose of fundraising

With this funding round, the startup plans to expand the recruitment process across engineering, research and operations talent within the country. Concurrently, it plans to install more indigenously produced BESS systems appropriate for India's grid.

VFlowTech also plans to employ the funds to develop vanadium recycling and establish innovation around electrolyte production in India to develop local supply chain efficiencies.

"With our artificial intelligence energy platform, we plan to construct digital minds to India's energy foundation, while expanding our domestic manufacturing capabilities and producing quality jobs in the country", Dr. Kumar further added.

"India is one of the most promising opportunities for energy transition. With its aggressive renewable energy goals and growing requirement of grid stability, combined with the policy momentum, our long-duration storage and AI-powdered systems are the ideal solution to deliver a secure, 24/7 clean power future", said Anand Anupam, Chief Commercial Officer of VFlowTech.

With a number of grid-scale and microgrid installations already installed, VFlowTech is in late-stage talks with renewable energy developers and industrial clients in India to install up to 1 GWh of VRFB systems in the next two to three years.

The total renewable energy installation capacity has grown to 220.10 GW, the highest increase ever of 29.52 GW in the FY 2024-25, according to the Ministry of New and Renewable Energy (MNRE).
