Using Redox Full Batteries to Power a Turbine?

I'm not seeing it going to be penciling out compared to pump storage or redox full batteries in many places. I personally think for the most part, chemical batteries are going to end up being the winners. We need stuff that is better than four to six hours of energy and the energy and the power are fairly tightly coupled. It's the decoupling of power and energy that pump hydrobrings and redox flow batteries bring.
