VFlowTech develops vanadium redox flow battery (VRFB) systems and hybrid batteries for long-duration energy storage and offers an AI-driven cloud energy management platform to manage, monitor and optimise distributed renewable assets. The platform also provides energy trading and ancillary services for the grid. Established in 2018 and based in New Delhi, the company has deployed its long-duration storage systems across more than 10 countries. VFlowTech raised $20.5M to support strategic expansion into India’s clean energy sector and to scale hiring across engineering, research and operations. The company plans to advance vanadium recycling and create innovations around electrolyte manufacturing in India to build local supply chain efficiencies. VFlowTech manufactures vanadium redox flow batteries branded as PowerCubes, featuring a power stack design that enables a more compact form factor, higher-than-industry round-trip efficiency, reduced parasitic losses and operation above 55°C. Different PowerCubes can be deployed from residential settings to solar and wind farms; the company has commercially deployed 30 kWh and 100 kWh units for residential applications and completed production of its MWh system for large-scale microgrid applications. Led by CEO Dr Avishek Kumar, VFlowTech employs a team of 60 people. The company raised US$10M in a Series A to support scaling and manufacturing. It intends to use the funds to set up a 200 MWh production line capacity and scale manufacturing of its 250 kWh modular vanadium-based long-duration energy storage solutions. VFlowTech also plans to expand its market presence to Türkiye, the US, Japan and India with new partners and to strengthen the management team over the next year. VFlowTech is a Singapore-based energy storage solutions provider that designs and manufactures long-duration modular batteries. Led by co-founder and CEO Dr. Avishek Kumar, the company has developed three modular systems—5 kW/30 kWh, 10 kW/100 kWh and 100 kW/500 kWh—that can be scaled to multi‑MWh deployments. A 10 kW/100 kWh system can provide up to two days of energy autonomy for small households and remote communities, the company says. In the past year VFlowTech has been delivering solutions to independent power producers, EPCs and other users worldwide and has a pipeline of large-scale infrastructure projects in markets including Australia and Africa. VFlowTech raised US$3M in a Pre‑Series A round and intends to use the funds to expand manufacturing and distribution of its long-duration modular batteries. The company aims to help remote and rural communities transition to low-cost reliable cleantech solutions and become diesel-free.
