Expanding Exploration in Queensland

The supply chain for vanadium redox flow batteries (VRFBs) is seeing significant strategic investments, particularly in Australia. Idemitsu Australia recently secured preferred tenderer status for 269 square kilometres of new vanadium exploration ground northeast of Julia Creek, Queensland. This adds to the company's existing footprint, having already committed over $75 million to the Julia Creek vanadium district. Idemitsu holds a majority stake in Vecco Group and interests in Critical Minerals Group's Lindfield project, targeting battery-grade vanadium and electrolyte production for VRFBs by the late 2020s.

Optimizing Production for High-Purity Vanadium

In North America, Largo Inc. is optimizing its production mix toward high-purity vanadium, which is supplied to vanadium electrolyte producers. An optimization study indicates the capacity to increase high-purity production to approximately 68% of total vanadium production, with overall vanadium pentoxide output expected to trend toward 876 tonnes per month.

Largo has produced and shipped its first high-purity vanadium pentoxide material for the U.S. Defense Logistics Agency (DLA). High-purity material represented only 4% of Largo's vanadium production in H1 2026, but vanadium oxides are currently exempt from U.S. import tariffs, allowing the company to significantly increase its high-purity product mix.

Supporting Infrastructure and Processing Hubs

To support these upstream developments, shared infrastructure is becoming critical. Queensland's A$115 million Queensland Resources Common User Facility (QRCUF), designed with vanadium processing in mind, will be fully operational by November 2026. This facility aims to support critical mineral developers and flow battery supply chains. Australian developer Vecco will use the QRCUF to demonstrate production capability for high purity vanadium pentoxide and vanadium electrolyte products, preparing for a final investment decision on its planned 300 MWh/yr Townsville electrolyte plant.
