Flow Batteries and Redox Flow Batteries are Energy Storage systems that work in tandem with Fuel Cell, Wind, Solar, Hydro, Fossil, Nuclear and traditional energy producing sources. They work by a method of passing Electrolytes from 2 independent tanks Anolyte and Catholyte, through cell stacks separated by membrane. The solutions used are either All Vanadium or Zinc/Bromine solutions, as they are currently the most commercially used electrolytes. Vanadium has 4 stages V2+ to V5+, 2 of which can be used on the negative side, and 2 can be used on the positive side for the reaction during the Reduction and Oxidation phases. When charging the Anolyte will react by giving up negative - electrons which transfer and attach to the electrons in catholyte solution as stored energy. This process is known as “Reduction” When the Energy is required, the process will run in reverse, giving the energy to be used back to the anolyte side from the stored energy. This process is known as “Oxidation”. Power output can be increased by increasing the number of stacks within the system, and Energy can be controlled by increasing or decreasing the solution tank dimensions.
