Metal hydrides (MHs) are regarded as highly desirable substances for both fixed and mobile hydrogen storage applications. Given that the hydrogenation dehydrogenation of metal exothermic endothermic processes involve substantial heat exchange, precise temperature control is essential. Various methods, including use phase change materials (PCMs), have been employed to manage this thermal behavior effectively. In study, sodium nitrate (NaNO3) was utilized in different geometric configurations store generated during reaction Mg2Ni with hydrogen. Computational fluid dynamics (CFD) methods were used conduct study. Therefore, three distinct geometries designed evaluate performance PCM MH beds reduce bed enhance reacted concentration within bed. By increasing PCM-to-MH volume percent from 1 18 absorption, decreases 627 620 K Case B 590 C 10,000 s. addition, maximum cases (A, B, C) 0.12, 0.8, 1, respectively. Finally, desorption process performed using NaNO3 A, became 0.17,
