Flow Battery Market: Definition/ Overview
A flow battery is a rechargeable electrochemical energy storage device that stores energy in two separate chemical solutions, divided by a membrane. The battery's energy capacity is scalable by increasing the size of the electrolyte tanks, making it ideal for large-scale energy storage. These batteries are particularly well-suited for grid-scale applications, where they can store surplus energy generated from renewable sources like wind and solar for use during periods of high demand or low generation.
Flow batteries address the intermittent nature of renewable energy by storing excess energy when demand is low and releasing it when needed, thereby enhancing grid stability and reliability. They also help reduce peak electricity demand by charging during off-peak hours and discharging during peak periods, resulting in lower electricity costs for both consumers and utilities.
