What's New

Mikey Brady-Raap

PNNL's Mikey Brady-Raap, the new president of the American Nuclear Society is pictured on the front page of July's Nuclear News. The publication includes a five-page spread on Brady-Raap's background. The White House Chronicle, a weekly PBS news and public affairs program, aired an interview on two Washington D.C. stations with Brady-Rapp.

The iron vanadium redox flow battery was developed by researchers at PNNL as a solution to large-scale energy storage for the power grid. This technology provides the energy industry and the nation with a reliable, stable, safe, and low-cost storage alternative for a cleaner, efficient energy future. See video.
