“…It has the advantages of non-toxic, self-lubrication, good dispersion and fluidity, high pressure resistance, low thermal conductivity, heat preservation, fire resistance, etc. As early as 1977, Teitel [80] proposed the use of micron-sized HGMs as a high-pressure hydrogen storage vessel and made a series of studies on it. The results showed that the hydrogen storage mass density of a HGM could reach the target value calibrated by the U.S. DOE vehicle hydrogen storage vessel in that year, and it was a very promising high-pressure hydrogen storage vessel.…”

Nowadays, high-pressure hydrogen storage is the most commercially used technology owing to its high hydrogen purity, rapid charging/discharging of hydrogen, and low-cost manufacturing. Despite numerous reviews on hydrogen storage technologies, there is a relative scarcity of comprehensive examinations specifically focused on high-pressure gaseous hydrogen storage and its associated materials. This article systematically presents the manufacturing processes and materials used for a variety of high-pressure hydrogen storage containers, including metal cylinders, carbon fiber composite cylinders, and emerging glass material-based hydrogen storage containers. Furthermore, it introduces the relevant principles and theoretical studies, showcasing their advantages and disadvantages compared to conventional high-pressure hydrogen storage containers. Finally, this article provides an outlook on the future development of high-pressure hydrogen storage containers.

“…A significant amount of research on the use of glass microspheres for hydrogen storage has been completed by Robert J. Teitel Associates (RJTA) under contract by the US. Department of Energy through Brookhaven National Laboratory [13][14][15][16]. In 1979 RJTA evaluated several commercial grades of glass microsphere, including Fillite 200/7 and 30017 and 3M D32/4500.…”

The state-of-the-art of hydrogen storage technology is reviewed, including gaseous, liquid, hydride, surface adsorbed media, glass microsphere, chemical reaction, and liquid chemical technologies. The review of each technology includes a discussion of advantages, disadvantages, likelihood of success, and key research and development activities. A preferred technological path for the development of effective near-term hydrogen storage includes both current DOT qualified and advanced compressed storage for down-sized highly efficient but moderate range vehicles, and liquid storage for fleet vehicle applications. Adsorbate media are also suitable for fleet applications but not for intermittent uses. Volume-optimized transition metal hydride beds are also viable for short range applications. Long-teim development of coated nanoparticulate or metal matrix high conductivity magnesium alloy, is recommended. In addition, a room temperature adsorbate medium should be developed to avoid cryogenic storage requirements. Chemical storage and oxidative schemes present serious In the future, nanoparticulate coated magnesium hydride, or coated metal matrix high conductivity hydride, having reduced absorption and release temperatures, offers safety, weight and volume efficiency provided the many technical obstacles can be overcome. Superabsorbent carbon needs development so that near room temperature absorption occurs, otherwise the cryogenic cooling and control requirements will hinder its acceptance in private vehicles. These hindrances may be acceptable in fleet vehicles. Microsphere technology should address stronger, more perfect spheres to allow and increase in storage pressure. Currently considered hydrogen-bearing media, or chemical reaction media, are deficient. Clearly breakthroughs are needed, making this a long-term option at best.

“…Storage and transportation of hydrogen in hollow glass microspheres (HGMS) has been proposed [1][2][3], but has been traditionally hindered by the slow release rates of hydrogen from the spheres.…”
