VFlowTech targets the growing long-duration energy storage market driven by renewable-energy intermittency and grid decarbonisation. The company is scaling a 100 MWh manufacturing plant in India into a gigafactory and expanding deployments across Asia, the Middle East and other global markets.
It also invests in supply-chain activities including vanadium recycling, electrolyte innovation and membrane advancements to reduce costs and secure materials for large-scale VRFB adoption.

VFlowTech's Powercube VRFB systems store energy in liquid electrolytes held in external tanks, allowing capacity to scale by adjusting tank volume rather than replacing hardware. The technology is non-flammable, does not degrade with repeated cycling, and is claimed to operate for more than 25 years with round-trip efficiency of about 80% at up to 100% depth of discharge.
The systems can operate in temperatures up to 55°C without active cooling, are configurable to both DC and AC installations, and are fully recyclable at end of life, addressing safety and longevity concerns associated with conventional lithium-ion batteries.
