Energy Storage

To date the PowerOasis has used conventional lead acid wet batteries as the energy storage element in trials. This battery technology is readily available, but is challenged in terms of cycle life, number of charge-discharge cycles, and its ability to withstand deep discharge.

PowerOasis will trial the integration of Vanadium Redox Flow battery technology into the solution, to provide power storage and significantly increase the number of times the batteries can be charged and discharged to potentially extend battery life.

Vanadium Redox Flow Battery (VRB) technology has been in development for several years. Unlike conventional batteries, the redox flow cell stores energy in its electrolyte, so that the capacity of the system is determined by the size of the electrolyte tanks, while the system power is determined by the size of the cell stacks. Additional electrolyte is stored externally in tanks and is pumped through the cells of the reactor where chemical energy is converted to electricity and the electrolyte can be discharged or recharged.
