The worlds demand for efficient energy storage systems has been growing steadily in the last 20 years as concerns over global warming and urban pollution have led to pressure from environmental groups for increased use of renewable energy technologies. In combination with renewable resources such as wind and solar, energy storage can increase the value of renewable generation, making supply coincident with periods of peak consumer demand. Vanadium redox flow batteries are ideal for storing electrical energy since they allow high energy conversion efficiencies to be achieved (over 80%) and long storage times.
Energy storage has become the critical issue for the world’s future energy supply and redox flow cells offer the best combination of energy efficiency, capital cost and life cycle costs compared with other technologies. The UNSW Vanadium Redox Flow Battery has been internationally acclaimed as the most promising technology currently available for new energy storage applications in the range from several kilowatts to several megawatts, with storage times up to several hours. The Energy Storage Association (http://www.electricitystorage.org) has compared the performance parameters of different types of energy storage systems ranging from flywheels, pumped hydro, capacitors and different battery technologies, and redox flow batteries are shown to have many technical benefits over other energy storage systems as well as an excellent combination of energy efficiency, capital cost and life cycle costs compared with other technologies.
