The Ce/H2 redox flow cell is a promising system for large-scale energy storage due to its high open circuit potential (OCV) relative to other aqueous systems.[1] The system consists of an electrochemical cell which is fed reactants from storage tanks containing gaseous hydrogen (negative side) and an aqueous solution of Ce3+ and Ce4+ (positive side). During discharge, hydrogen … [Read more...] about Improved Cerium-Hydrogen Redox Flow Cell

Popular Science Highlights MyGreenCar App
An app developed at Berkeley Lab to help car consumers evaluate green vehicle choices based on individual driving styles and routes was the focus of a June 20 article in Popular Science titled "Which Electric Car is Right for You?" Researcher Sam Saxena expects the app to be in potential car buyers' hands in 2017, thanks to a partnership with the EPA and DOE. Last year, Saxena … [Read more...] about Popular Science Highlights MyGreenCar App
