2.4 Applications of Redox Flow batteries Flow batteries are normally considered for relatively large (1 kWh – 10 MWh) stationary applications6: Load balancing – where the battery is connected to an electrical grid to store excess electrical power during off-peak hours and release electrical power during peak demand periods. The common problem limiting the use of most flow battery chemistries in this application is their low areal power (operating current density) which translates into a high cost of power. Storing energy from renewable sources such as wind or solar for discharge during periods of peak demand. Peak shaving, where spikes of demand are met by the battery. Uninterruptible power supply (UPS), where the battery is used if the main power fails to provide an uninterrupted supply. Power conversion – The electrolyte/s may be charged using a given number of cells and discharged with a different number, because all cells share the same electrolyte/s. Because the voltage of the battery is proportional to the number of cells used the battery can therefore act as a very powerful DC–DC converter. In addition, if the number of cells is continuously changed (on the input and/or output side) power conversion can also be AC/DC, AC/AC, or DC–AC with the frequency limited by that of the switching gear. Electric vehicles – Because flow batteries can be rapidly "recharged" by replacing the electrolyte, they can be used for applications where the vehicle needs to take on energy as fast as a combustion engine vehicle. A common problem found with most RFB chemistries in the EV applications is their low energy density which translated into a short driving range. Flow batteries based on highly soluble halides are a notable exception. Stand-alone power system – An example of this is in cell phone base stations where no grid power is available. The battery can be used alongside solar or wind power sources to compensate for their fluctuating power levels and alongside a generator to make the most efficient use of it to save fuel. Currently, flow batteries are being used in solar micro grid applications throughout the Caribbean. Furthermore, economically convenient and technically competitive storage solutions must ensure not only response time and storage capacity suitable for meeting both the generation and grid needs but, must also show a long lifetime and be able to withstand many charge/discharge cycles. Present-day technologies are characterized by different levels of development and are suitable for different storage and localization needs9,10. Modular technologies such as redox flow battery (RFB) offer the capability of high power rating, long energy storage time and excellent response time: full power can be delivered in few seconds. 16PDF Image | Redox Flow Batteries Vanadium to Earth Quinones
