Hydrogen Distribution and Storage

A hydrogen fuel cell is environmentally friendly, but H2 is much more difficult to store than liquid fuels. The production, distribution, and storage of hydrogen present major difficulties, so researchers are working on fuel cells that use liquid hydrocarbon fuels. One such fuel cell is composed of layers of yttria-stabilized zirconia (YSZ), which is solid Zr02 containing around 5% Y2 O3. This cell uses the combustion of a... 

Decentralised hydrogen production from natural gas for onsite applications (fuel cells, refuelling stations for hydrogen vehicles) eliminates or reduces the problems of distribution and storage. Nevertheless, current technology has high costs because it lacks economy of scale. Lower pressure and temperature and lower-cost materials are... 

The kind of manufacture, transportation, and distribution infrastructure required to support a hydrogen-based fuel cell vehicle will be tied directly to the form of hydrogen used on board the vehicle. For example, on-board storage of molecular hydrogen allows a broad spectrum of raw material precursors to manufacture hydrogen. With a chemical carrier, however, molecular hydrogen may not be needed, and the manufacture, transportation, distribution, and storage systems would be quite different. 

Alternatives to Molecular Hydrogen Transportation, Distribution, and Storage... 

Spiral shaped hollow nanofibers were formed from the reaction of p-aminophenyl-p-D-glucopyranoside and p-dodecanoylaminophenyl-p-o-glucopyranoside with excess tetraethoxysilane. The diameter distributions of these tubes ranged from 1 to 2 nm and from 3 to 7 nm. Metal oxide nanotubes derived from this process displayed excellent hydrogen adsorption and storage capacity for potential use in hydrogen-powered vehicles.
