Sciencedaily reported about Silicon Nanotubes For Hydrogen Storage In Fuel Cell Vehicles in Apr. 24, 2008. In the study, Cao's group used powerful molecular modeling tools to compare the hydrogen storage capacities of newly developed silicon nanotubes to carbon nanotubes. They found that, in theory, silicon nanotubes can absorb hydrogen molecules more efficiently than carbon nanotubes under normal fuel cell operating conditions. The calculations pave the way for tests to determine whether silicon nanotubes can meet government standards for hydrogen storage, the scientists note.
