VRB Power Systems suggests they have an Energy Storage Solution CANADA - JD Holdings Inc acquired all the outstanding common stock of VRB Power Systems (VP), a manufacturer of electrical energy storage system, US7227275 - Method for retrofitting wind turbine farms - 06/05/2007 A power generation system with a predetermined rating limit includes one or more wind turbine generators and a vanadium redox battery. The vanadium redox battery absorbs excess energy to ensure that the rating limit is not exceeded, provide system stability, and improve power generation availability. The power generation system may further include a control system to manage the vanadium redox battery's absorption and power generation to control system stability and system frequency.

I got an interesting comment on one of my posts about distributed power generation and storage. Charles Toca representing Prudent Energy VRB Energy Storage System ( VRB - ESS ) says they have an energy storage system base on the the vanadium-based redox regenerative fuel cell that converts chemical energy into electrical energy. This is from their website: -Editor How It Works The VRB Energy Storage System ( VRB - ESS ) is an electrical energy storage system based on the patented vanadium-based redox regenerative fuel cell that converts chemical energy into electrical energy. Energy is stored chemically in different ionic forms of vanadium in a dilute sulphuric acid electrolyte. The electrolyte is pumped from separate plastic storage tanks into flow cells across a proton exchange membrane ( PEM ) where one form of electrolyte is electrochemically oxidized and the other is electrochemically reduced. This creates a current that is collected by electrodes and made available to...
