Abstract

This thesis focuses on investigating the efficiency of hydrogen storage using various experimental rigs and cooling methods. The primary objective is to explore the potential of hydrogen densification through the utilization of an Aerogel blanket—a nanoporous material capable of slowing down hydrogen molecules and achieving gas densification close to its liquid density at medium pressures and a readily attainable temperature of 77K. The study encompasses three distinct experimental setups, each designed and tested for this specific investigation. The first experimental apparatus is a small, low-pressure rig that incorporates external cooling. This setup allows for preliminary testing and analysis of the hydrogen storage efficiency. The second apparatus is a large-scale rig with internal cooling, enabling a more comprehensive evaluation of hydrogen densification at varying pressures. Finally, a small, high-pressure rig with external cooling is utilized to examine the behavior of hydrogen under extreme conditions, specifically pressures ranging from 1 bar to 100 bar, with the working media being hydrogen gas at liquid nitrogen conditions (77K). The results of the experiments revealed significant hydrogen densification within the test rigs due to the presence of nanoporous media. The storage techniques employed in this study proved to be highly effective in achieving densification, offering a potential solution that bridges the gap between costly and inefficient liquid hydrogen storage and high-pressure gas hydrogen storage at ambient temperature conditions. By exploring the efficiency of hydrogen storage through experimental means and employing innovative approaches such as the Aerogel blanket and varying cooling methods, this research contributes to advancing the field of hydrogen storage technologies. The findings hold promise for the development of more practical and accessible storage solutions, potentially facilitating the widespread adoption of hydrogen as an alternative energy source.
