VFlowTech, a Singapore-based energy storage solutions firm, has successfully raised $20.5 million in its latest funding round.

The firm said in a statement on Wednesday that the investment was led by prominent venture capital firm Granite Asia, joined by new investors Antares Ventures, EDBI, MOL PLUS and PSA Ventures and alongside existing backers İnci Holding, UntroD Capital, Pappas Capital, Wavemaker Partners, SEEDS Capital, and Entrepreneurs First.

This funding will enable VFlowTech to scale manufacturing and deployment of its proprietary vanadium redox flow batteries (VRFBs); strengthen its AI-driven cloud energy management platform to optimize efficiency and unlock new revenue streams; develop critical supply chains, including vanadium recycling, electrolyte innovation, and membrane advancements.

With Singapore positioning itself as a global hub for sustainability and smart energy solutions, VFlowTech said its artificial intelligence (AI)-powered platform will introduce advanced smart grid functionalities to enable customers to optimize energy use, participate in energy trading, and enhance the return on investment (ROI) of energy storage systems.

With this investment, the firm will accelerate its expansion across Asia, the Middle East, and other global markets, grow its commercial team, and deepen its presence in key sectors such as utilities and grid-scale storage, renewable integration, and industrial decarbonization.

“As industries and governments prioritize sustainability, VFlowTech is at the forefront of providing advanced storage solutions that optimize energy usage and reduce environmental impact,

“With this investment, we are poised for significant growth and technological advancement,” said Avishek Kumar, Founder and Chief Executive Officer of VFlowTech.

Arjun Bhattarai, Co-Founder of VFlowTech, also said that this funding gives the firm the ability to take on larger projects, expand into new markets, and integrate cutting-edge digital intelligence into its energy storage solutions—making them not just storage systems, but revenue-generating assets.

Established in 2018, VFlowTech is a deep tech company pioneering vanadium redox flow battery (VRFB) systems for long-duration energy storage.

The firm focuses on developing safe, scalable, and sustainable energy storage solutions.

It has installed their long duration storage systems in over ten countries globally and is supporting Singapore’s ambition to be a global leader in clean energy innovation and with the vision to drive the world towards energy equity where everyone can access clean energy at affordable pricing.

“Long duration energy storage is critical in supporting 100% renewable energy, build out of electric vehicle (EV) infrastructure, and new energy demand required from accelerated AI adoption,

“We believe that VFlowTech and vanadium flow battery technology is well positioned to capture this market in Asia and beyond. We’re excited to collaborate with the team to realise a more sustainable future for all,” said Kheng Nam Lee, Venture Partner of Granite Asia.

Meanwhile, Michael Gryseels, Founder and Managing Partner at Antares Ventures, said that Antares Ventures has supported VFlowTech from its inception, recognizing early the transformative potential of its battery technology.

According to him, over six years, the company has grown from a university research project into a leading innovator in long duration energy storage, driven by exceptional scientific talent and strong commercial execution.

“VFlowTech’s solutions uniquely address Asia’s urgent need for affordable, clean energy and improved grid stability, directly enhancing energy security in the region,

“We look forward to continuing our support alongside visionary investors and strategic partners committed to securing Asia’s energy future,” he added.

Takuya Sakamoto, Chief Executive Officer of MOL PLUS, said the firm finds two attractions in VFlowTech.

“The first is that their technology has the potential to be deployed in larger-scale facilities, such as port terminals. The second is their focus regions are Southeast Asia and India where is also MOL’s focus,

“We will continue our contribution in business collaboration,” he said.
