Our systems
As renewable energy sources increasingly integrate into the grid, operators encounter significant challenges in maintaining voltage and frequency stability. This includes managing the variability of intermittent power and ensuring that energy availability remains optimal while minimizing curtailment. Current battery solutions with a duration of four hours or less are not adequately equipped to meet these demands in a cost-effective manner.
Product offering
Energy storage built around your requirements
Our modular vanadium redox flow battery systems are designed to scale with your energy needs, site constraints and operational requirements.
FlowOne
100kW / 500 kWH in a 40 Foot Container
Our Flagship Containerized solution boasts an All-in-One “Plug and Play” solution that marries long duration energy storage with quick deployment. Best suited for Commercial and Industrial use cases with energy requirements below 2,500kWh.

The VFT Proprietary Technology Advantage
01 / “HeatShield” Electrolyte

Patented Electrolyte manufacturing process to increase the stability of the electrolyte when operating in high ambient temperature environments up to 55 deg Celsius without needing active cooling. The reduction in cooling auxiliary consumption materially increases Round-Trip Efficiency (RTE) and leads to best-in-class throughput energy generation and compelling Levelized Cost Of Storage (LCOS) in demanding climates.
02/ Patented Vanadium Recovery
VFT is the first flow battery supplier globally with the patented technology to recover Vanadium from PetCoke cinder, which contains high concentration of Vanadium metals – Allowing us to achieve full vertical integration of our supply chain, ensuring our portfolio of robust, resilient and cost-competitive solutions.
03/ “FlowFlex” Design Architecture
VFT’s design and engineering expertise allow us to partner with customers for creative solutioning to space and site specific constraints, without compromising on the power or energy requirements of the user. We have deployed/in pipeline projects for fully indoor systems, external electrolyte tanks (horizontally and vertically), underground/submerged electrolyte tanks, non-containerized stack designs, etc.
