The U.S. Army is testing a new flow battery from Lockheed Martin at Fort Carson in Colorado.
Flow battery technology features electrolyte storage for long-duration, large-capacity clean energy storage.
The GridStar flow battery, which can provide up to one megawatt for up to 10 hours, should be operational in 2024.
The U.S. Army recently began testing something called a “flow battery” at Fort Carson, Colorado. If successful, the flow battery, which is powered by two chemical components dissolved in liquids that are pumped through the battery system, could someday help bring long-duration, large-capacity energy storage to many U.S. military bases.
In partnership with Lockheed Martin, the U.S. Army Engineer Research and Development Center team at the Construction Engineering Research Laboratory (CERL) Operational Energy broke ground late last year on GridStar Flow, a rechargeable redox flow battery featuring electrochemistry consisting of engineered electrolytes.
“Bottom line is, the Lockheed Martin flow battery will provide a feasible means of long-duration grid scale energy storage to Fort Carson and their mission-critical assets that no other Army installation currently possesses,” Tom Decker, Army program manager, said in a news release. “This is a significant tool and has potential to make an impact on future military bases.”
