If one considers 50 MW (net) wind or solar farm a 1.0 MW capacity of the VRB would store and discharge 2 % of net production continually.

When one considers the total cost to put in the 50 MW (net) installation, the cost of the completed VRB (my guestimate) could be over (5x - 8x) the $600,000 cost of material alone. In effect the cost as a percentage of a total 50 MW (net) Plant is not high.

Relative to EV charging times and distances traveled for the Vanadium, Lithium, Phosphate Battery, check these news releases.

Then there is potential for direct VRB use in EV's,

In addition Hybrids using the Vanadium, Lithium, Phosphate Battery is another market.

I believe that Cellstrom is selling small VRB units for off the grid use.
