Breakthrough in energy storage battery technology

How long can a battery store energy?

Handling the fluctuating power production of renewables will require cheap storage for hours or even days at a time. New types of iron-based batteries might be up to the task. Oregon-based ESS, whose batteries can store energy for between four and 12 hours, launched its first grid-scale projects in 2021.

How do flow batteries store energy?

Flow batteries, like the one ESS developed, store energy in tanks of liquid electrolytes—chemically active solutions that are pumped through the battery’s electrochemical cell to extract electrons. To increase a flow battery’s storage capacity, you simply increase the size of its storage tank.

Can batteries unlock other energy technologies?

Batteries can unlock other energy technologies, and they’re starting to make their mark on the grid. This article is from The Spark, MIT Technology Review ’s weekly climate newsletter.

Could new iron batteries help save energy?

New iron batteries could help. Flow batteries made from iron, salt, and water promise a nontoxic way to store enough clean energy to use when the sun isn’t shining. One of the first things you see when you visit the headquarters of ESS in Wilsonville, Oregon, is an experimental battery module about the size of a toaster.

Are iron-based batteries up to the task?

New types of iron-based batteries might be up to the task. Oregon-based ESS, whose batteries can store energy for between four and 12 hours, launched its first grid-scale projects in 2021. Massachusetts-based Form Energy, which raised $240 million in 2021, has batteries that store power for up to 100 hours.

Why are energy storage devices important?

Energy storage devices have become indispensable for smart and clean energy systems. During the past three decades, lithium-ion battery technologies have grown tremendously and have been exploited for the best energy storage system in portable electronics as well as electric vehicles.
