Flowcell battery uses electrolyte tanks to make electricity

http://www.nanoflowcell.com/technology/

Take a look and what do you think about what is like a fuel cell.
Supposedly this is for cars, planes, boats, generators.

Two tanks of liquid ionic fuel are mixed across a membrane to create electric power, the waste fluid is discarded as salt water solution.

But how cheap is the fuel going to be?
I wonder what if the fuel mixes together in an accident?

 

It is a lot of hype and no scientific explanation or data.

 

The de-energized fluid is recycled to be recharged and reused. The chemistry is nasty. They are as attractive as a nuclear waste site at the moment. A nuclear waste site with a lot of pumps and small tanks and piping and transfer operations. The chemistry may improve somewhat, but chemists and engineers have already been working on this stuff for over a century, it is not an easy thing to do.

There have been some interesting suggestions for using flow batteries as general purpose electrical converters. Fluid can be recharged with any sort of AC or DC source, and can be pumped to any sort of battery and switching network to produce any desired electrical output, with a good bit of storage capacity built in. Grid tie solar converters and grid tie wind turbine converter systems based on flow batteries have been proposed.

The quixotic nerd in me can imagine a farmer pulling his electric tractor up to his wind turbine and replacing the plant-based electrolyte that is stored and re-energized in the turbine base. Whether this would be an improvement over a pair of oxen, I don't know.
