Abstract

Hydrogen storage and delivery technology is still a bottleneck in the hydrogen industry chain. Among all kinds of hydrogen storage methods, light-weight solid-state hydrogen storage (LSHS) materials could become promising due to its intrinsic high hydrogen capacity. Hydrolysis reaction of LSHS materials occurs at moderate conditions, indicating the potential for portable applications. At present, most of review work focuses on the improvement of material performance, especially the catalysts design. This part is important, but the others, such as operation modes, are also vital to to make full use of material potential in the practical applications. Different operation modes of hydrolysis reaction have an impact on hydrogen capacity to various degrees. For example, hydrolysis in solution would decrease the hydrogen capacity of hydrogen generator to a low value due to the excessive water participating in the reaction. Therefore, application-oriented operation modes could become a key problem for hydrolysis reaction of LSHS materials. In this paper, the operation modes of hydrolysis reaction and their practical applications are mainly reviewed. The implements of each operation mode are discussed and compared in detail to determine the suitable one for practical applications with the requirement of high energy density. The current challenges and future directions are also discussed.
