Hydrogen Absorption by Nanostructured Carbons. Carbon-based materials show great promise for clean energy storage through the absorption and desorption of hydrogen. The project aims to use powerful theoretical and experimental methods to resolve the controversy that surrounds reports of massive hydrogen absorption by nanostructured carbons, by understanding why particular structures should or should not absorb hydrogen atoms or molecules. We will particularly study and model intercalated graphit ....Hydrogen Absorption by Nanostructured Carbons. Carbon-based materials show great promise for clean energy storage through the absorption and desorption of hydrogen. The project aims to use powerful theoretical and experimental methods to resolve the controversy that surrounds reports of massive hydrogen absorption by nanostructured carbons, by understanding why particular structures should or should not absorb hydrogen atoms or molecules. We will particularly study and model intercalated graphite and nanotubes made in Australia. Their hydrogen capacity will be compared to the US DOE target of 6.5 weight percent for viable automotive hydrogen fuel storage. Reproducibly exceeding this target would constitute a great advance in the field.Read moreRead less
