H2 BREAKTHRU BUT H2 STILL A CONCEPT

Researchers Create Catalysts for Use in Hydrogen Storage Materials
24 March 2009 (Virginia Commonwealth University via Newswise)

"A team of scientists from Virginia Commonwealth University, the University of Uppsala in Sweden, and the Savannah River National Laboratory have identified that carbon nanostructures can be used as catalysts to store and release hydrogen, a finding that may point researchers [one step closer to] developing the right material for hydrogen storage for use in cars…

"According to [Puru Jena, Ph.D., distinguished professor in the VCU Department of Physics], complex hydrides are a class of materials that have shown promise for the storage of hydrogen. Because complex hydrides are not reversible and removing hydrogen from them is difficult at temperatures less than 100°C, catalysts are needed to improve the reaction rates. However, previous studies indicate that the addition of catalysts creates defects in the hydrides."

Good research project. But "maybe someday" is a real problem in a world that needs answers now...(click to enlarge)

"The experimental group led by Ragaiy Zidan, Ph.D., a researcher at the Savannah National Laboratory, developed a solvent technique which allowed the introduction of carbon fullerenes and nanotubes without introducing any defects and also functioned as catalysts. Jena and the team at the University of Uppsala led by Rajeev Ahuja, Ph.D., performed theoretical calculations to illustrate the mechanism of how these catalysts work.

"The study appears online and in the journal Nano Letters, a publication of the American Chemical Society. The work was supported by a grant from the U.S. Department of Energy…"
