Singapore-based long-duration energy storage innovator VFlowTech has raised $20.5 million to advance its AI energy management systems, deploy vanadium redox flow batteries (VRFB), support grid-scale storage, boost renewable integration, and promote industrial decarbonization across Asia and beyond.

“This funding gives us the ability to take on larger projects, expand into new markets, and integrate cutting-edge digital intelligence into our energy storage solutions, making them not just storage systems, but revenue-generating assets,” said Dr. Arjun Bhattarai, co-founder of VFlowTech.

VFlowTech secured this latest round of funding to supercharge its vision for long-duration energy storage. Granite Asia led the round, joined by Antares Ventures, EDBI, MOL PLUS, PSA Ventures, and returning supporters like İnci Holding, UntroD Capital, Wavemaker Partners, and Entrepreneurs First.

Founded in 2018, VFlowTech has steadily emerged as a powerhouse in the long-duration energy storage sector, deploying VRFB systems in over 10 countries. This new capital will fuel the company’s ambition to transform its 100 MWh manufacturing facility in India into a full-scale Gigafactory.

AI-Powered Energy Optimization at Scale

The company will use the funds to strengthen its AI energy management platform, which is designed to optimize energy flow, reduce waste, and offer ancillary services to the grid. This AI-driven system complements VFlowTech’s vanadium redox flow batteries, providing smarter, longer-lasting power solutions for a carbon-neutral future.

CEO Dr. Avishek Kumar emphasized the need for sustainable systems that help industries and governments meet net-zero goals, stating that this investment marks “a turning point for scalable innovation in clean energy.”

VFlowTech plans to deploy VRFB systems across microgrids, commercial operations, and utility-scale projects. Talks are underway with major renewable developers in India to roll out up to 1 GWh of storage systems shortly.

With India’s Ministry of New and Renewable Energy reporting a 29.52 GW boost in clean capacity this fiscal year, VFlowTech positions itself as a crucial partner in the country’s drive to reach 500 GW of non-fossil fuel power by 2030.

“Long-duration energy storage is critical in supporting 100 percent renewable energy, the build-out of EV infrastructure, and the new energy demands required by accelerated AI adoption. We believe VFlowTech and vanadium flow battery technology can capture this market in Asia and beyond,” said Kheng Nam Lee, venture partner of Granite Asia.

Driving Industrial Decarbonization and Resilient Grids

The startup’s focus also extends to reshaping critical supply chains. VFlowTech aims to advance vanadium recycling, electrolyte innovation, and membrane technologies, key elements in improving battery longevity and affordability.

A long-time backer, Antares Ventures’ Michael Gryseels, remarked that VFlowTech’s journey from a university research project to a global energy innovator “reflects the company’s unique blend of scientific excellence and commercial acumen.”

As it accelerates growth, VFlowTech will expand into the Middle East and other global markets, building a robust commercial team and targeting key sectors such as grid-scale storage, renewable integration, and industrial decarbonization.

This strategic expansion aligns with the urgent need for resilient, clean energy storage worldwide, a goal that VFlowTech advances with each deployment of its vanadium redox flow batteries.

“We found two attractions in VFlowTech. The first is that their technology has the potential to be deployed in larger-scale facilities, such as port terminals. Second, their focus regions are Southeast Asia and India, which are also MOL’s focus. We will continue contributing to business collaboration,” said Takuya Sakamoto, CEO of MOL Plus.
