Competitive advantage
- Redox flow batteries offer lower cost and longer cycle life than conventional battery systems with no thermal issues
- Up to 200,000 cycles for a vanadium flow battery demonstrated in commercial wind system
- Lower risk than Li-ion technology – no emissions or fire hazards
- Advanced battery control approaches based on mechanisms of electrochemical reactions to improve efficiency and flexibility of battery operation
- Use of vanadium batteries for simultaneous electricity quality control and power demand/supply balance (without supercapacitors) to reduce the capital and maintenance costs of systems
Impact
- The vanadium flow battery developed at UNSW is currently manufactured commercially by companies in Japan, China, USA, UK and Germany. A 200 MW/800 MWh VRB is currently being installed in Dalian, China.
Successful applications
- Vanadium flow battery developed at UNSW now manufactured commercially
- Licensing of vanadium battery technology to international sponsors
- Development of a vanadium oxygen laboratory scale fuel cell system
- Scale-up of an iron slurry flow battery system
Capabilities and facilities
- 30 kW/130 kWh commercial VRB system
- Dedicated computation laboratories for advanced simulation modelling and associated facilities for validation studies
- Extensive state-of-the-art electrochemical and mechanical laboratories
- Advanced additive and automated manufacturing facilities
