Anyone have experience with Vanadium Redox batteries?
Basics: http://en.wikipedia.org/wiki/Vanadium_redox_battery
Looks like REDT Energy Storage Systems has designed a 5KW module, which would be about perfect for me (current conventional designs utilize a 4400 W inverter).
Adding capacity is pretty much as simple as adding more flow tanks - like putting a bigger gas tank on your car while maintaining the same engine.
It SEEMS like this would be a good fit for us, but progress has been slow. There use to be one company, VRB, down in Australia, that was doing research and spot product placements/demos. They went under. Now there are half-a-dozen or so companies pitching to different markets.
I just love the characteristics: Same chemical on both sides of the plate, just in different electron charge states. Virtually no power leakage. Charge membranes with 35 year lives. Modular. Reasonably efficient (1.1:1 charge:discharge power ratio).
Just curious if anyone has practical experience or has done other research into this.
