| Hydrogen Can Lurk in Ice for Fuel Use Korea Advanced Institute of Science and Technology, Professor Lee Huen "Purified water does not have a space to embed hydrogen but we found water combined with organic metals creates a nano-space to stably hoard hydrogen at about 0 degrees Celsius when water turns to ice," Lee said. Lee's team applied for international patents for the breakthrough. The finding will be featured in the next edition of the science journal Nature.

| NANERGY (ObjectSoft/GEMZ Corp) Kimberly Peacock Hydrogen storage on C60 (Bucky balls) In addition, the Company expects to license the development and commercialization rights for a Nanotechnology Using Thermal Acoustic Methods for Production of Carbon 60, also known as Buckminster Fullerenes or Buckey balls for the efficient storage of hydrogen in carbon nanotubes. The Company is in the process of licensing this technology from Kimberly Peacock. Link GEMZ Corp., a nanotech startup, is set to acquire an exclusive license to a new thermal acoustic process for the production of bucky balls�C60�to be used for the storage of hydrogen. While the technology is still conceptual, and its development is �uncertain and fraught with risk,� according to GEMZ, it could open the way for hydrogen storage in C60 at a cost two orders of magnitude lower than current technology permits. GEMZ estimates that the thermal acoustic technique is potentially more efficient than the four methods currently used for producing C60, all of which consume too much energy in the manufacturing process for them to be cost effective.

| NIST - Taner Yildirim, Salim Ciraci Using established quantum physics theory, they predict that hydrogen can amass in amounts equivalent to 8 percent of the weight of "titanium-decorated" singled walled carbon nanotubes. That's one-third better than the 6 percent minimum storage-capacity requirement set by the FreedomCar Research Partnership involving the Department of Energy and the nation's "Big 3" automakers. As important, the four hydrogen molecules (two atoms each) that link to a titanium atom are relinquished readily when heated. Such reversible desorption is another requirement for practical hydrogen storage.

Erkoc Department of Physics, Middle East Technical University, Ankara 06531 Turkey We obtained perfectly Ti-covered nanotubes and at both temperatures (1K, 300K) with again no any significant distortion in the SWNT and no clusterization of Ti atoms. This is one of the most important results of this study. Link |

| John Tse, University of Saskatchewan Steacie Institute for Molecular Sciences Technical University of Dresden Graphite films only nanometers or billionths of a meter thick could help store hydrogen in an inexpensive, easily manufactured, lightweight and nontoxic manner, an international team of scientists told UPI's Nano World. They found graphite layers spaced slightly less than a nanometer apart can store hydrogen at room temperature and moderate pressures at close to a good weight. So the researchers contend graphite is a better option than carbon nanotubes, because it is far easier and less expensive to prepare. Another good possibility is the use of porous carbon foams.

| Argonne Labs/Hydrogen Storage Researchers at the U.S. Department of Energy's Argonne National Laboratory have combined the world's hardest known material � diamond � with the world's strongest structural form � carbon nanotubes. This new process for �growing� diamond and carbon nanotubes together opens the way for its use in a number of energy-related applications. Link Link to Advanced Materials Abstract |
