Abstract

Hydrogen adsorption in porous nanostructured polyaniline (PANI) has been investigated to determine its potential as a hydrogen storage media. Residual gas analysis and thermogravimetric analysis were used to investigate the cyclical hydrogen adsorption in PANI. A hydrogen storage capacity of up to 3 wt % was obtained by charging the polymers at up to 3.0 × 106 Pa hydrogen at elevated temperature. Multiple charge and discharge cycles have been shown, with good retention beyond 106 sec.

Abstract

This annual report documents the activities and contributions accomplished during FY79 on a research contract aimed at assessing the feasibility of transporting hydrogen gas through the existing natural gas pipeline network. Studies of the hydrogen-induced degradation of pipeline steels reveal that hydrogen can be transported in these steels if a number of precautions are taken. These issues are discussed and plans for further research are presented. Document type: Report
