VFlowTech raised $10M to build a 200 MWh line for vanadium flow batteries

Singapore maker of modular vanadium-based redox flow batteries for long-duration energy storage

Modular vanadium redox flow batteries with a 25-year expected life can win long-duration storage, backed by a 200 MWh production line and expansion into new countries

$10M Series A led by Real Tech Holdings, with SEEDS Capital, Wavemaker Partners, Sing Fuels, Michael Gryseels, İnci Holding, Pappas Capital and Carbon Zero Venture Capital

VFlowTech was established in 2018 by Dr Avishek Kumar (CEO) and Dr Arjun Bhattarai (CTO) with Entrepreneur First, with support from SG Innovate and Nanyang Technological University, Singapore.

By February 2023 it had commercially deployed 30 kWh and 100 kWh units for residential use and had produced an MWh-scale system for large microgrids. Deployments ran through joint partnerships in Africa and Southeast Asia, with two batteries due on Singapore's Pulau Ubin that year. On 2023-02-07 it announced a $10M Series A to set up 200 MWh of production capacity and scale manufacturing of its 250 kWh modular systems, expand into Turkey, the US, Japan and India, intensify R&D and strengthen management. A binding framework agreement with İnci Holding would help bring the technology to Turkey.

Customers asked for storage for EV charging, peak shifting, grid services, gated communities and telecom towers

A non-degrading electrolyte supports a long 25-year life, which suits long-duration storage

Production capacity of 200 MWh is needed to supply grid-scale projects beyond pilots

Partnerships such as İnci Holding give entry to markets like Turkey

Energy storage startups often use their first institutional round to move from pilots to a first production line, and the performance claims in the article are the company's own.

As of 2023-02-07, VFlowTech had a $10M Series A, deployed small residential units and an MWh system, and planned a 200 MWh production line and expansion to four new markets.
