VFlowTech, a leading provider of sustainable long-duration energy storage solutions, has announced a capital raise of USD 20.5 million to support its strategic expansion into India’s clean energy sector. The funding will further the company’s goal of accelerating India’s transition to renewables through long-duration energy storage and AI-based energy management technologies.
The investment will enable VFlowTech to scale its existing 100 MWh manufacturing facility in India into a Gigafactory. It will also support the wider rollout of its Vanadium Redox Flow Batteries (VRFBs) across India’s fast-growing renewable energy landscape.
The funding round was led by Granite Asia, with participation 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 highlights growing investor confidence in VRFB technology, which is increasingly seen as vital to stabilising renewable-heavy grids and enabling large-scale decarbonisation. With India’s energy market undergoing rapid transformation and electrification expanding across sectors, VFlowTech’s modular and scalable battery systems aim to address the rising need for resilient and sustainable power infrastructure.
VFlowTech’s VRFB systems offer 25-year life cycles, high safety standards, and deep discharge capabilities without performance degradation. These features make them a strong alternative to lithium-ion batteries for utility-scale installations, microgrids, and commercial and industrial energy use.
The company’s storage technology is complemented by an AI-powered cloud energy management platform that manages, monitors, and optimises energy usage across distributed renewable energy assets. It also enables energy trading and provides ancillary services to support grid stability.
“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 for India’s energy backbone, while scaling local manufacturing and creating high-quality jobs in the country,” he added.
VFlowTech plans to increase hiring across engineering, research, and operations teams in India, and intends to deploy more domestically manufactured battery energy storage systems (BESS) tailored to local grid conditions. Part of the funding will also be used to develop vanadium recycling capabilities and innovations in electrolyte production to enhance local supply chains.
“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 underway, the company is in advanced discussions with renewable developers and industrial clients in India to deploy up to 1 GWh of VRFB systems over 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,” Anupam added. “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), India’s total installed renewable energy capacity has reached 220.10 GW, marking a record increase of 29.52 GW in FY 2024–25. This milestone is a key step towards achieving 500 GW of non-fossil fuel capacity by 2030 under Prime Minister Narendra Modi’s ‘Panchamrit’ climate goals—targets that will require substantial investment in long-duration storage alongside new renewable generation.
