VSUN Energy is an Australian renewable energy company specializing in vanadium flow battery (VFB) technology for energy storage solutions. Established in 2016 as a subsidiary of Australian Vanadium Limited, VSUN Energy develops and implements advanced energy storage systems for various sectors, including utility-scale projects, commercial applications, and residential installations. The company’s focus on VFB technology offers distinct advantages in long-duration energy storage, emphasizing safety, reliability, and environmental sustainability. Their systems provide storage solutions that can operate for over 25 years with minimal performance degradation, making them particularly suitable for renewable energy integration and grid stabilization.
Battery Technology
VSUN Energy’s vanadium flow batteries represent a significant advancement in energy storage technology. These systems utilize vanadium ions in different oxidation states to store and release energy, offering unique capabilities that distinguish them from conventional battery types. The technology allows for simultaneous charging and discharging without performance loss, while the non-flammable nature of the electrolyte ensures exceptional safety standards.
The modular design of VSUN’s VFB systems enables scalability from kilowatt to megawatt applications, adapting to specific energy requirements. A notable feature is the ability to reuse the vanadium electrolyte indefinitely, minimizing environmental impact and supporting circular economy principles. The company benefits from its parent organization’s vanadium electrolyte production facility in Perth, ensuring a reliable supply chain for their battery systems.
The technology excels in applications requiring extended discharge durations, maintaining consistent performance regardless of cycle depth or frequency. This makes it particularly effective for renewable energy storage, grid stabilization, and backup power systems where long-duration capability is essential.
Recent Projects
In 2024, VSUN Energy achieved significant progress with Project Lumina, developing a 100 MW vanadium flow battery energy storage system. The company partnered with GenusPlus Group for electrical connections and Sedgman for plant design services. The project demonstrates competitive energy storage costs, achieving AUD 274/MWh for four-hour systems and AUD 251/MWh for eight-hour systems.
Additionally, VSUN Energy installed a 5kW/30kWh vanadium redox flow battery at Water Corporation’s innovation hub in Shenton Park, WA, testing applications for mobile water purification units and standalone power systems.
Investors
VSUN Energy operates as a wholly-owned subsidiary of Australian Vanadium Limited (ASX: AVL), which provides primary funding and strategic support. AVL’s position as an emerging vanadium producer ensures vertical integration within the supply chain, supporting VSUN Energy’s growth and development in the energy storage market.
