How do flow batteries work?

Flow batteries: Design and operation A flow battery contains two substances that undergo electrochemical reactions in which electrons are transferred from one to the other. When the battery is being charged, the transfer of electrons forces the two substances into a state that’s “less energetically favorable” as it stores extra energy.

Can flow batteries be used for large-scale electricity storage?

Associate Professor Fikile Brushett (left) and Kara Rodby PhD ’22 have demonstrated a modeling framework that can help speed the development of flow batteries for large-scale, long-duration electricity storage on the future grid.

Are flow batteries intrinsically linked?

Because of the specific technology, stored energy in and power supplied by flow batteries are not intrinsically linked. This feature makes them especially suitable for storage systems for renewables, especially for uses with long discharge times.

How can MIT help develop flow batteries?

A modeling framework developed at MIT can help speed the development of flow batteries for large-scale, long-duration electricity storage on the future grid.

How do flow batteries increase power and capacity?

Since capacity is independent of the power-generating component, as in an internal combustion engine and gas tank, it can be increased by simple enlargement of the electrolyte storage tanks. Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell.

What are redox flow batteries?

Specifically, redox flow batteries represent one type of grid-scale energy storage device with long life spans of at least 10 years and capabilities like peak shaving and load leveling.
