What is a flow battery?
The larger the electrolyte supply tank, the more energy the flow battery can store. Flow batteries can serve as backup generators for the electric grid. Flow batteries are one of the key pillars of a decarbonization strategy to store energy from renewable energy resources.
How long does a flow battery last?
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.
What is an iron-based flow battery?
Iron-based flow batteries designed for large-scale energy storage have been around since the 1980s, and some are now commercially available. What makes this battery different is that it stores energy in a unique liquid chemical formula that combines charged iron with a neutral-pH phosphate-based liquid electrolyte, or energy carrier.
Can iron-based aqueous flow batteries be used for grid energy storage?
A new iron-based aqueous flow battery shows promise for grid energy storage applications. A commonplace chemical used in water treatment facilities has been repurposed for large-scale energy storage in a new battery design by researchers at the Department of Energy's Pacific Northwest National Laboratory.
Can a flow battery be modeled?
MIT researchers have demonstrated a modeling framework that can help model flow batteries. Their work focuses on this electrochemical cell, which looks promising for grid-scale energy storage—except for one problem: Current flow batteries rely on vanadium, an energy-storage material that’s expensive and not always readily available.
Why do we need flow batteries?
Flow batteries are one of the key pillars of a decarbonization strategy to store energy from renewable energy resources. Their advantage is that they can be built at any scale, from the lab-bench scale, as in the PNNL study, to the size of a city block. Why do we need new kinds of flow batteries?
