You mean flow batteries in general or just vanadium redox? Because if it's in general, why would you think its opportunity window is closing?

Closed batteries have no inherent advantage on large scale stationary projects, only problems. The only gain they bring is that you can ride on the scale of mobile applications.

I'm waiting for the old car batteries to start coming online, I think that will kill anything else for stationary systems, and will just get bigger.

You can't discharge and recharge a lead acid car battery very many times before it loses capacity.

I didn't believe it was necessary to specify this, but I meant Lithium car batteries, not lead.

Ah, sure, that makes more sense. I have to retrain myself to think of "car batteries" as something other than a heavy, plastic box of acid.
