PPOT brain trust, thoughts and comments on this please?

If true and practical, it sounds like a real solution (har har) for lots of problems.

I have been interested in flow batteries, as utility-scale storage, but have never thought that flow batteries could be competitive with or superior to conventional (solid) batteries in energy density or could be recharged by replacing the discharged solution with charged solution rather than recharging the solution in situ.
