VSUN’s vanadium flow batteries use vanadium ions in varying oxidation states within a non-flammable electrolyte to store and release energy simultaneously without degradation. The modular systems scale from kilowatt to megawatt applications, feature indefinite electrolyte reuse, and leverage parent-company production in Perth for supply chain security. Designed for extended discharge durations, they maintain consistent performance across cycles.
Modular VFB systems ranging from kilowatt to 100 MW capacity, offering over 25 years of operational life with minimal capacity loss. Features include simultaneous charge/discharge capability, non-flammable electrolyte, indefinite electrolyte reuse, and scalability. A 5 kW/30 kWh vanadium redox flow battery model has been deployed for mobile water purification and standalone power tests.
Project Lumina: a 100 MW VFB energy storage system completed in 2024 in partnership with GenusPlus Group (electrical connections) and Sedgman (plant design), achieving costs of AUD 274/MWh (4-hour) and AUD 251/MWh (8-hour). A 5 kW/30 kWh VFB installed at Water Corporation’s Shenton Park innovation hub for mobile water purification and standalone power trials.
VSUN Energy is wholly owned by Australian Vanadium Limited (ASX: AVL), which provides primary funding and vertical integration through its Perth vanadium production facility.
