Abstract: Todays, environmental impacts as well as depletion of fossil fuels have simulated scientist's efforts to find alternative, renewable, and neat energy resources. Recently, hydrogen has been introduced as a clean and high-density energy resource which has satisfied all foregoing demands. There are many challenges which has been defined in storage sector. Recently, nanomaterials, especially graphene, have been employed in this regard. In this study, the potential of graphene-based materials have been embossed. It has been proved that heteroatoms, especially nitrogen as dopant in graphene nanosheet, assist the Gravimetric hydrogen density (GHD). Also, decorated graphene by both alkali and transition metals (TMs) have shown promise results. Furthermore, dopant-decorated systems have been defined desirable toward higher HSC; e.g. nitrogen-doped Pd decorated graphene has been studied as one of the best hybrid system in this manner. In addition, density functional theory (DFT) has been considered and confirmed the assessment.
