空心玻璃微球储氢研究进展.

With the continuous use of fossil fuels, the emission of CO2 increases significantly, which seriously affects nowadays’ ecology. In order to reduce the emission of CO2, it’s urgent to use clean energy to replace fossil fuels. Hydrogen energy has advantages of high heat value and zero CO2 emission, making it a good substitute of fossil fuels. However, its small density and low boiling point make it difficult to storage, which limits its large-scale application. At present, hydrogen energy is stored in high-pressure tanks, which have disadvantages of low hydrogen capacity, high cost of transportation and hydrogen embrittlement. The key point of large-scale commercial application of hydrogen is developing new kind of hydrogen storage materials and technologies. Hollow glass microspheres (HGMs) as a kind of hollow, small size and pressure-resistant material, have advantages of good stability, high hydrogen capacity, low cost and no hydrogen embrittlement, which make them have great potential in hydrogen storage. This paper reviews the development of hydrogen storage in HGMs, introduces the mechanism and influencing factors of hydrogen storage in HGMs and further introduces the research of hydrogen release rate and response time.
