fuel cells

Large-scale storage of low-pressure, gaseous hydrogen in salt caverns and other underground sites for transportation fuel and grid-scale energy applications offers several advantages over above-ground storage, says a recent Sandia National Laboratories study sponsored by the Department of Energy’s Fuel Cell Technologies Office.

New semiconducting material works at temperatures low enough to improve fuel cell efficiency.

A novel combination of microscopy and data processing has given researchers at the Department of Energy’s Oak Ridge National Laboratory an unprecedented look at the surface of a material known for its unusual physical and electrochemical properties.
