New Pillared Graphene Material Offers Enhanced Hydrogen Storage; Close to DOE Target

Posted on October 01, 2008

Volumetric hydrogen uptake for graphene (diamonds), (6,6) carbon nanotubes (squares), pillared material (triangles), and Li-doped pillared (stars) at (a) 77 K and (b) 300 K. Click to enlarge. Credit: ACSResearchers at the University of Crete (Greece) have designed a novel 3-D network nanostructure that almost meets the US Department of Energy (DOE) 2010 volumetric goals for hydrogen storage. The new pillared graphene material could theoretically store up to 41 grams of hydrogen per liter under ambient conditions; the DOE s target is 45 g/L. Their study is scheduled for the 8 October issue of...
