General criteria for selection of materials for the processing of hydrogen separation membranes are discussed. Performance and stability standards required for applications in high temperature membrane reactors have been focused. The correlations between pore structure and stability issues of membranes made of amorphous materials, specifically silica membranes are discussed in detail.

Hydrogen separation membranes can be used to produce H2-rich streams for either H2 production or power generation with pre-combustion CO2 capture. In the latter case, high purity H2 is not required since it is used to fuel a combustion turbine in fact, dilution with membrane sweep gases such as steam and N2 actually reduces NO, formation by reducing the stoichiometric combustion temperature. In H2 production, high purity H2 (>99.9%) is generally required and only steam, which is easily separated by condensation, can be used as a sweep gas.
