Flow Batteries 101: Redefining Large‑Scale Energy Storage
You might worry about cost-effectiveness for small-scale flow batteries, but they can actually save you money long-term. While scalability challenges and maintenance
A research team from the Department of Energy's Pacific Northwest National Laboratory reports that the flow battery, a design optimized for electrical grid energy storage, maintained its capacity to store and release energy for more than a year of continuous charge and discharge.
Flow batteries provide long-lasting, rechargeable energy storage, particularly for grid reliability. Unlike solid-state batteries, flow batteries store energy in liquid electrolyte, shown here in yellow and blue.
The basic technology behind flow batteries was first patented back in the 1870s. Leveling them up for 21st century applications has been a challenge. Nevertheless, in recent years flow batteries have begun seeping into the stationary energy storage marketplace.
Some of the performance benefits of flow batteries include: The demand for dependable long duration energy storage to facilitate grid stability, energy independence, and renewable integration is propelling the market for flow batteries.
