In this article, individual options for the implementation of hydrogen storage systems in vehicles are analysed. In particular, the conventional methods are described and hydrogen storage systems that use metal hydride alloys are discussed. The article presents the design of a low-pressure pressure vessel with a maximum operating pressure of 3MPa, compliant with the STN EN 13322-2 requirements. The newly-designed metal hydride pressure vessel was subjected to a strength analysis in the Ansys Static Structural environment at a maximum test hydraulic pressure of 4.7MPa. The measurement data describing the amount of the stored hydrogen which was obtained during the process of the activation of Hydralloy C5 is also analysed. The analysis included three cycles of hydrogen absorption and desorption.

Keywords: Hydrogen storage, metal hydride, strength analysis, finite element method.
