New All-Liquid Iron Flow Battery for Grid Energy Storage

The aqueous iron (Fe) redox flow battery here captures energy in the form of electrons (e-) from renewable energy sources and stores it by changing the charge of iron in the flowing liquid electrolyte. When the stored energy is needed, the iron can release the charge to supply energy (electrons) to the electric grid. (Animation by Sara Levine | Pacific Northwest National Laboratory)

Research Partners: The University of Akron

A commonplace chemical used in water treatment facilities has been repurposed for large-scale energy storage in a new battery design by researchers at PNNL. The design provides a pathway to a safe, economical, water-based, flow battery made with Earth-abundant materials. READ MORE

Scientists Put Forth a Smarter Way to Protect a Smarter Grid

PNNL scientists have put forth a new approach to protect the electric grid that sorts and prioritizes cyber threats on the fly. READ MORE
