Two publicly backed financings in the same week have put state capital at the centre of vanadium flow battery (VRFB) manufacturing capacity, one on the cell side and one on the electrolyte side.

UK: National Wealth Fund anchors Invinity

The UK state-owned National Wealth Fund (NWF) announced a cornerstone investment leading a £25 million fundraise by vanadium flow battery maker Invinity Energy Systems. The move makes a government-backed institution the anchor investor in a listed VRFB manufacturer — a signal that London views flow batteries as domestic industrial capacity rather than purely a technology bet.

Cornerstone backing of this kind matters beyond the cash. For a company selling multi-decade assets to utilities and industrial buyers, a state balance sheet behind the manufacturer is a bankability argument as much as a funding one.

Western Australia: AU$15 million for relocatable electrolyte

The Western Australian government awarded AU$15 million (US$10.4 million) to Australian Vanadium Limited (AVL) for a relocatable vanadium electrolyte manufacturing facility. Funding comes from the state's Investment Attraction Fund, New Energies Industries Round 2.

The facility is described as high-capacity with a modular, relocatable design for deployment across regional and industrial centres in WA, intended to expand AVL's electrolyte production and increase local content in the VRFB supply chain. AVL already operates a vanadium electrolyte plant in Perth, completed in December 2023 with support from a federal Modern Manufacturing Initiative grant, and its subsidiary VSUN Energy supplied a 78kW/220kWh VRFB for a long-duration energy storage pilot in Kununurra with state-owned utility Horizon Power.

Why electrolyte, specifically

Electrolyte is the volume-driven half of a flow battery's bill of materials, and it is the part of the supply chain most concentrated in China. James Costello, chief executive of Australian VRFB developer EORA Energy, said vanadium electrolyte is still mostly produced in China, attributing that to state subsidies and market scale.

"There is plenty of electrolyte — cost is the issue," Costello said, adding that EORA plans to source raw material from outside China for future projects.

That framing explains the policy logic. A relocatable plant does not need to beat Chinese unit costs to be useful; it needs to shorten lead times, satisfy local-content rules in tenders such as Western Australia's 50MW/500MWh Kalgoorlie VBESS, and give developers a non-Chinese sourcing option.

What to watch

The two deals sit at different ends of the chain: Invinity's £25 million supports stack and system manufacturing, while AVL's grant targets the chemistry. Whether both translate into contracted volume depends on tender outcomes in the UK and Australia over the next 24 months.
