Hydrogen Storage in Metal Hydrides

reportActive / Technical Report | Accession Number: ADA228150 | Open PDF

Abstract:

The primary objective of this program was to develop an economical process for producing a lightweight hydrogen storage medium by the chemical vapor inflitration CVI of a metal hydride former into a reticulated foam substrate. An investigation was conducted to determine the most favorable precursors for forming the candidate hydride-forming materials, along with optimization of their transport and deposition parameters. A substrate optimization study was also performed in order to derive the greatest surface area-to-volume ratio from the resulting metal hydride-forming foam. Thermogravimetric analysis TGA was performed on a metal foam sample to determine its hydriding capability. Results were inconclusive, showing only slight if any hydriding. js
