Abstract:

This study introduced several high-pressure gaseous hydrogen storage containers, including high-pressure hydrogen storage cylinders, high-pressure composite hydrogen storage tanks, and glass hydrogen storage containers. High-pressure hydrogen storage cylinders include all-metal gas cylinders and fiber composite material-wound gas cylinders. The only commercially available high-pressure hydrogen storage container has the advantages of easy hydrogen release and high hydrogen concentration. The high-pressure composite hydrogen storage tank used hydrogen storage materials to store hydrogen and achieve solid hydrogen storage; the gap between the powder materials also participated in hydrogen storage to accomplish gas-solid mixed hydrogen storage. This method had the advantages of high volumetric hydrogen storage density, fast hydrogen charging speed, and good working performance at low temperatures. The glass hydrogen storage containers included hollow glass microspheres and a capillary glass array. This was a new type of high-pressure hydrogen storage container that had the advantages of high mass and volume density, good safety, low-cost parameters, and did not undergo hydrogen embrittlement. It was initially anticipated that this type of container would be combined with fuel cells and applied to various electronic mobile devices. However, due to imperfections in its related supporting devices, additional development is required for its commercial application. This paper compared the performance of several commercial high-pressure hydrogen storage tanks. It focused on the hydrogen storage mechanism, the technical status, and the research related to glass hydrogen storage tanks. It posited future technical research directions related to several types of hydrogen storage tanks.

Key words: high-pressure gaseous hydrogen storage, high-pressure gas cylinders, hollow glass microspheres, glass capillary arrays
