President Barack Obama at the Winning the Future Forum on Small Business in Cleveland, OhioVanadium redox flow battery as "One of the coolest things he has ever said out loud" at Cleveland State. Ashlawn Energy's flow battery seeks to modernize the electric grid and create a new high-tech manufacturing sector in Northeast Ohio.
This interview is terrible. This technology is not new, just a new design to an old system. This type of battery just doesn't work. It has a poor efficiency of around 65%. Worse yet is its energy density, which requires insane volumes of deionized water. 1MWh of storage is over 17,500 gallons. While very interesting, this tech has a long way to go to become viable. It may never be viable.
Why does the interviewer state the professor is the inventor of the VRB? She may have been the first with a successful demonstration and holder of the patent for the current design (pardon the pun!), but the Vanadium redox couple was first mentioned in a patent of 1933 (PA Pissoort, FR Patent 754 065 (1933)) and then again in another by A. Pelligri and PM Spaziante, in GB Patent 2030349 (1978).
Why is it that a technology that dates back to 1933 (and explored by NASA as well in the 1960's) is till not mainstream? The answer lies in the low power and energy densities associated with running the same vanadium electrolyte either side of the membrane. Just 1 MWh of storage will require 100,000 litres of electrolyte.
Imagine the wind farm in the recent order for E.ON Vind Sverige AB for delivery of 16 units of the V90-2.0 MW wind turbine. The order has a total capacity of 32 MW to be installed in Nybro, Lilla Edet and Öringe. Storing the entire output for just 4 hours overnight will require 12.8 million litres of electrolyte. That's over 5 full sized Olympic sized pools.
Add on top of this the abysmal round trip efficiency of not much more than 60% (in the field operations, not lab/bench work), and it is clear why this old technology is not make the inroads that many thought it should. Emperor's new clothes and all that.
Why haven't more people heard of this groundbreaking technology?!? Finally a storage system that is highly efficient, has 100% discharge/recharge capability, and could be as simple to recharge as changing the electrolyte... now we just need a catchy trendy name to get more attention... it's like a battery and a fuel cell... maybe we could call it a hybrid fuel cell/battery. The word hybrid seems to catch people's attention
The vanadium redox battery will revolutionize the whole renewable energy sector. Dr. Kazacos should get a Nobel for this. If you want to stay on top of all things related to vanadium battery technology then follow @VanadiumJoe on Twitter. Turns out vanadium added to lithium ion batteries will increase the power/weight ration by a factor of 5! This makes for a battery with a power/weight ratio even better than gasoline!!!
@VanadiumJoe has disappeared. You can follow @EnergizerResInc since they also have a lot of info on the vanadium battery. Also Treehugger has some good stuff on there.
nice discussion..

So far it is the very best solution to store energy.
Now since Jan. 2011, Professor Maria Skyllas-Kazacos she join Apella Resources as Advisory Board.

Currently studying her for HSC ;s
Her development within energy storage and cells are indeed revolutionary <3

Vanadium will power everything soon.
