One such solution gaining considerable attention is flow batteries – an advanced energy storage technology that holds great promise for the future. In this article, we will explore the latest advancements in flow batteries and their role in accelerating the transition to clean energy.
The Basics of Flow Batteries
Before diving into the advancements, let’s first understand the basic principles of flow batteries. Unlike traditional batteries, flow batteries store energy in chemical fluids contained in external tanks known as electrolyte tanks. These tanks, coupled with the battery’s core, called the cell stack, work together to deliver power when needed.
Flow batteries are malleable compared to conventional batteries, as power and energy are decoupled. This means that by altering the size of the tanks, energy capacity can be increased, making them a flexible solution for various applications. Moreover, flow batteries have longer lifetimes as they do not experience the same degradation issues as conventional batteries, such as lithium-ion batteries.
