What VFlow Tech does

VFlowTech Pte Ltd is a Singapore-headquartered deep tech company founded in 2018 as a spin-out of Nanyang Technological University's CleanTech Lab, specializing in long-duration energy storage through proprietary Vanadium Redox Flow Battery (VRFB) technology. Its core product, the PowerCube 100-500, is a modular VRFB system scalable from 100kW to 500kW configurations, featuring 25% higher energy density than conventional flow batteries, operation above 40°C without active cooling, 100% depth of discharge, a 25-year expected lifespan, and 100% recyclability. The technology stack integrates an in-house Battery Management System (BMS) and Energy Management System (EMS) and is supported by 9 patents held by the CTO.

The company generates revenue primarily through project-based hardware sales and deployment of VRFB systems to enterprise customers, targeting utilities and grid operators, telecom tower operators, commercial and industrial facilities, EV charging infrastructure, and remote/off-grid communities across more than 11 countries in Asia-Pacific, Africa, the Middle East, and Australia. Go-to-market is direct enterprise field sales, supplemented by event-driven engagement (Singapore International Energy Week, Asia Clean Energy Summit) and channel/EPC partnerships. Operational footprint includes a Singapore headquarters and Cleantech Hub presence, manufacturing in India, and a wholly-owned subsidiary in Africa plus a Liv Energy joint venture. Strategic partnerships include NTU, IIT Delhi (FITT), the Singapore Energy Market Authority's Virtual Power Plant Sandbox, Infosys, and Resync for AI-powered monitoring. Cumulative funding raised is approximately $33.5 million across Pre-Series A (October 2021), Series A (February 2023), and Series A+ (May 2025) rounds, with Granite Asia leading the latest round.

Revenue model

1. VRFB System Sales and Deployment: VFlowTech generates revenue primarily through the sale and deployment of its PowerCube vanadium redox flow battery systems. Systems are sold directly to enterprise customers including utilities, telecom operators, commercial & industrial facilities, and governments for long-duration energy storage applications. Revenue is project-based, typically involving system sizing, custom engineering, installation, and commissioning.
2. Vanadium Supply Chain / Circular Ecosystem: Through the IIT Delhi collaboration, VFlowTech is developing a circular vanadium ecosystem in India — recovering high-purity vanadium pentoxide from refinery waste (petcoke) for use in battery electrolyte. This may support electrolyte leasing or domestic supply models.
