A market analysis is developed to determine economic parameters. Capital cost and profitability of different battery sizes are assessed. The results of prudential and perspective analyses are presented.

Do vanadium redox flow batteries use more than one element?

Unlike other RFBs, vanadium redox flow batteries (VRBs) use only one element (vanadium) in both tanks, exploiting vanadium’s ability to exist in several states. By using one element in both tanks, VRBs can overcome cross-contamination degradation, a significant issue with other RFB chemistries that use more than one element.

Can redox electrolytes increase VRB operating temperatures?

These efforts will build on Pacific Northwest National Laboratory research that has developed new redox electrolytes that enable increased VRB operating temperatures and energy storage capacities.
