The cool thing with flow batteries is that you can scale the amount of power they store (kwh) by simply using bigger tanks. The power output (kw) you get out of them is determined by the size and efficiency of the anode and cathode.

So, in this case both are a bit underwhelming obviously. But the main point is that you can increase the kwh by simply using bigger tanks and the kw by using multiple cells in parallel or by improving the anode/cathode somehow.

What are possible dangers ? I am thinking that any potential sudden release of energy would make placement in urban areas unsafe.
