Company profile
researched Aug 2026VFlowTech (VFT) is a Singapore-headquartered energy storage company that designs and manufactures modular vanadium redox flow batteries (VRFB) for long-duration energy storage (LDES). The company was incubated in the CleanTech lab of Nanyang Technological University (NTU) and holds intellectual property on battery stacks, electrolyte chemistry and energy management systems derived from several years of university research.
Its flagship product line, the PowerCube, is offered in 50kW/250kWh and 100kW/500kWh configurations. The company states an expected system lifetime of more than 25 years, round-trip efficiency of 80% at up to 100% depth of discharge, operation at ambient temperatures up to 55°C without active cooling, and configurability for both DC and AC installations. VFlowTech has also developed its own energy management system (EMS), including a cloud-based platform intended to optimise charging profiles, integrate with solar PV, and enable smart-grid functions such as energy trading.
Applications span grid-scale, distributed and off-grid deployments. The company has worked on underground energy storage sites in Singapore, has trialled its technology with EV charging infrastructure, and positions VRFB technology against lithium-ion on safety (lower fire risk), recyclability, absence of degradation and the ability to decouple energy from power by sizing electrolyte tanks independently of the stack.
