Nanyang Technological University, Singapore (NTU Singapore) and Singapore-based energy storage company VFT have launched a S$15 million joint research laboratory dedicated to vanadium redox flow batteries (VRFBs).
The NTU-VFT Joint Lab, run through the Energy Research Institute @ NTU (ERI@N), will work on batteries that are safer, more durable and more cost-effective for storing renewable electricity and supporting future power grids.
Safety as a design parameter
The lab's central technical premise is chemistry. VRFBs store energy in non-flammable, aqueous-based liquids, which significantly reduces the risk of battery fires compared with conventional lithium-ion systems. As storage deployments move closer to population centres, substations and industrial facilities, that characteristic is shifting from a niche selling point to a procurement criterion.
The research targets safer, longer-lasting and lower-cost grid-scale storage — three variables that have historically traded off against one another in flow battery development.
The cost problem the lab has to solve
Flow batteries are durable and fire-safe, but they remain capital-intensive. Stack costs, membrane materials and vanadium electrolyte — the single largest line item — all weigh on upfront pricing, and lithium-ion remains a formidable competitor in applications of up to roughly eight hours of duration.
That framing explains why a university-industry partnership of this size matters. Academic groups can pursue membrane chemistry, electrolyte formulations and degradation science over multi-year horizons, while an industrial partner supplies real duty cycles, field data and a route to manufacturing. The S$15 million commitment suggests both sides expect findings to reach commercial systems rather than remain in journals.
Durability is the second front
Long asset life is the flow battery's structural advantage: a system with slow capacity fade can be justified on levelised cost even at a higher headline capex. But that advantage only holds if membranes resist degradation, electrolyte stays balanced across thousands of cycles, and balance-of-plant components survive decades of operation. Each of those is a materials science problem, which is precisely what a joint lab is built to attack.
Why Singapore
Singapore's interest is straightforward: a dense, land-constrained grid with limited options for bulk renewables needs storage that is compact in risk terms, and a regional research hub that anchors supply chain expertise. If the NTU-VFT lab produces results that lower cost per kilowatt-hour while preserving the safety profile, the payoff extends well beyond the island's own grid.
