Technical FAQs 4

How much does an iron-based flow battery cost?

Companies like ESS Tech, Inc. in the USA have made significant strides in developing and commercializing acidic all-iron ARFBs and the U.S. Advanced Research Projects Agency-Energy estimates that this iron-based flow battery would achieve an energy storage cost as low as $125 per kWh .

What is the capital cost of flow battery?

The capital cost of flow battery includes the cost components of cell stacks (electrodes, membranes, gaskets and bolts), electrolytes (active materials, salts, solvents, bromine sequestration agents), balance of plant (BOP) (tanks, pumps, heat exchangers, condensers and rebalance cells) and power conversion system (PCS).

How much does an aqueous flow battery cost?

As reported in the literature , the production cost of both aqueous and non-aqueous flow batteries is ca. $120/kWh and it is clear the chemical cost of the aqueous system is much lower. Obviously, a potent approach to promote the cost performance of RFBs is adopting low-cost active aqueous species as the supporting electrolytes.

Are aqueous iron-based flow batteries suitable for large-scale energy storage applications?

Thus, the cost-effective aqueous iron-based flow batteries hold the greatest potential for large-scale energy storage application.
