The global vanadium redox flow battery (VRFB) market will expand rapidly between 2025 and 2030, with analysts estimating a compound annual growth rate (CAGR) of 20–25%. The growing need for large-scale energy storage solutions is driving this surge, as countries work to integrate renewable energy and strengthen grid stability. The Asia-Pacific region, in particular, will lead both production and deployment, propelled by proactive government incentives and strong industrial momentum.
Strategic Collaboration to Extract Vanadium Domestically
In a breakthrough move for India’s clean energy landscape, VFlowTech—a leader in long-duration energy storage—has partnered with the Foundation for Innovation and Technology Transfer (FITT), the industry outreach arm of IIT Delhi. Together, they will develop a process to recover high-purity vanadium from petroleum coke (petcoke) cinder, a by-product of India’s vast oil refining sector. The collaboration marks the beginning of India’s first circular vanadium ecosystem. It focuses on converting industrial waste into battery-grade vanadium pentoxide (V₂O₅)—a vital material for next-generation VRFBs.
Waste-to-Value: Building a Resilient Supply Chain
India currently imports most of its vanadium despite being one of the world’s top oil refiners. Refinery operations produce large quantities of petcoke cinder, rich in vanadium content. By tapping into this overlooked resource, the VFlowTech–IIT Delhi initiative aims to create a sustainable, homegrown supply of vanadium. This effort will strengthen India’s energy storage value chain and support the national goal of energy self-reliance.
“India’s refinery scale presents a unique opportunity to build a homegrown vanadium ecosystem. By repurposing waste into battery materials, we’re addressing energy security and industrial sustainability in one step,” said Dr. Avishek Kumar, Co-Founder and CEO of VFlowTech.
Driving India’s Clean Energy Goals
The initiative aligns with India’s ambitious clean energy goals. In FY 2024–25 alone, the country added a record 29.52 GW of renewable capacity. This brought the total installed renewable capacity to 220.10 GW. India has set an ambitious national target of 500 GW of non-fossil energy capacity by 2030 under Prime Minister Modi’s ‘Panchamrit’ pledge. To support this goal, localizing vanadium production becomes a critical enabler of scalable and sustainable energy storage.
“We are delighted to be a part of this transformative initiative. By establishing India’s first circular vanadium ecosystem, we aim to support the vision of creating 500 GW of renewable energy by 2030. This partnership will further elevate India’s clean energy transition by strengthening the domestic supply chain,” noted Professor Anil Verma, Department of Chemical Engineering, IIT Delhi.
VFlowTech’s PowerCubes: Next-Gen VRFB Innovation
At the heart of VFlowTech’s clean energy mission is its advanced Vanadium Redox Flow Battery system, known as PowerCubes. These modular, long-duration storage systems offer several advantages over conventional battery technologies:
*Compact Power Stack Design: Maximizes energy density and minimizes space requirements.
*High Efficiency: Achieves superior round-trip energy efficiency, reducing energy loss.
*Extreme Climate Resilience: Operates reliably in temperatures exceeding 55°C—ideal for tropical regions where lithium-ion batteries face challenges.
Backed by Funding, Driven by Innovation
Powered by a recent $20 million Series A+ funding round, VFlowTech is investing heavily in India’s clean energy future. As per the press release, the collaboration with IIT Delhi reflects VFlowTech’s commitment to advancing local R&D capabilities. It also aims to develop a fully indigenous vanadium value chain—from extraction to battery production.
