LOW-PRESSURE ADSORPTION STORAGE OF HYDROGEN

The amount of gas that can be stored in an adsorption system is dictated by the nature of the adsorbent material and the operating conditions of the storage system, namely the storage pressure and temperature. This paper describes the impact of these factors on H, storage. The discussion is based on measurements of hydrogen adsorption on commercially available and densified adsorbents. The measurements were carried out in the pressure range 1-80 arm and at different storage temperatures using a high-pressure volumetric method. The results show that the adsorption technique could provide a viable method for hydrogen storage.
