RICHLAND, Wash. - Energy storage system owners could see significant savings from a new flow battery technology that is projected to cost 60 percent less than today's standard flow batteries.
The organic aqueous flow battery, described in a paper published in the journal Advanced Energy Materials, is expected to cost $180 per kilowatt-hour once the technology is fully developed. The lower cost is due to the battery's active materials being inexpensive organic molecules, compared to the commodity metals used in today's flow batteries.
