Abstract

Hydrogen storage is a very important component of the hydrogen economy. A low storage density in conventional pressure and cryogenic vessels, for which it is necessary to use high pressures or very low temperatures, is the issue of the broader application of this element. Therefore, the various types of metal hydride and adsorption storage vessels are extensively tested. Hydrogen adsorption technology on to carbon materials is effective only at cryogenic temperatures and therefore liquid nitrogen with a temperature of 77 K (-196.15 °C) was used to reduce the temperature of the storage device. This article discusses the possibilities of using cryogenic temperatures for hydrogen adsorption on to materials with a large surface area while using liquid nitrogen to reduce temperature. A volume method for measuring the amount of adsorbed hydrogen was used to determine and quantify the amount of hydrogen stored.
