In the continuing effort to find cheaper, lighter, safer methods of storing hydrogen for use as a vehicle fuel, researchers from DaimlerChrysler, Ohio University and Inergy are investigating the use of plastic foams. The idea is to store the hydrogen within the pores of a spongelike material. So far they have yet to approach the goals that were set by the 2007 FreedomCAR project which was to achieve a storage density of 0.036 kg H2/liter of storage material volume. The best they have achieved to

During the recent International Congress of Nanotechnology in San Francisco, California researchers presented a potential new method of storing hydrogen. Frantisek Svec, of the Lawrence Berkeley National Laboratory, and Jean Fréchet, of the University of California in Berkeley, revealed that they had set a new record for storing hydrogen using a nanoporous polymers. They produced a storage medium made from styrene full of microscopic pores, sort of a sponge with really tiny holes.
