“…Different materials have been studied for electrochemical hydrogen storage such as different composite materials including nanostructured Ni/ graphene (Ni/GNS) (with electrochemical hydrogen storage capacity of 160 mA h g À1 [8]), palladium-doped graphene/ carbon composites (0.82 wt%) [13], graphene sheets prepared by DC-Arc discharge method (147.8 mA h g À1 ) [14], purified and opened single walled carbon nanotubes (800 mA h g À1 ) [15], purified single-walled carbon nanotubes (SWCNTs) (316 mA h g À1 ) [16], multi-walled carbon nanotubes (MWCNTs) decorated by TiO 2 nanoparticles (NPs) with the capacity of 540 mA h g À1 [17] and other hybrids [18,19]. In this method, hydrogen is produced by water decomposition on the surface of a polarized electrode in an electrochemical cell and hydrogen is absorbed in the electrode as a hydrogen storage material [14,17,19].…”

“…Water is readily intercalated and dispersed between the sheets as a result of hydrophilicity. The following equation shows the oxidation mechanism:

6 K M n O_{4 ((), a q)} + 9 H_{2} S O_{4 ((), a q)} \Rightarrow 6 M n S O_{4 ((), a q)} + 3 K_{2} S O_{4 ((), q)} + 9 H_{2} O_{(1)} + 5 O_{3 ((), g)}

In this study, different types of graphene were synthesized to investigate hydrogen adsorption capacity at different pressures (0–34 bar) at room temperature (298 K). Graphene and nanoporous graphene were prepared by Chemical Vapor Deposition (CVD) method, using methane as a carbon source at a temperature of 900 °C over copper plates and nickel oxide nanocatalyst. The nickel oxide nanocatalyst was prepared by sol–gel method, whereas graphene oxide was prepared through modified Hummer's method. The products were characterized by X‐ray diffraction, field emission‐scanning electron microscopy, energy dispersive spectroscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, Brunauer–Emmett–Teller and Raman spectroscopy. The adsorption of hydrogen was done by volumetric method. High adsorption capacity was achieved in nanoporous graphene because of its high pore volume (2.11 cm3/g) and large specific surface area (850 m2/g). Hydrogen adsorption values for nanoporous graphene, graphene and graphene oxide were determined as 2.56, 1.70 and 0.74 wt%, respectively. In addition, the hydrogen adsorption of graphene nanostructures fitted nicely to the selected two‐parameter and three‐parameter adsorption isotherm models. The adsorption isotherm model coefficients have been found for a 0–34 bar pressure range. The parameter values for all adsorbents showed proper conformity to the model and experimental data.

“…Moreover, the oxide can be decorated with nanoparticles, just like graphene. The experimental results currently indicate hydrogen adsorption in such structures reaching 5 wt.% [ 112 , 113 , 114 , 115 , 116 ].…”

The energetic and climate crises should pose a challenge for scientists in finding solutions in the field of renewable, green energy sources. Throughout more than two decades, the search for new opportunities in the energy industry made it possible to observe the potential use of hydrogen as an energy source. One of the greatest challenges faced by scientists for the sake of its use as an energy source is designing safe, usable, reliable, and effective forms of hydrogen storage. Moreover, the manner in which hydrogen is to be stored is closely dependent on the potential use of this source of green energy. In stationary use, the aim is to achieve high volumetric density of the container. However, from the point of view of mobile applications, an extremely important aspect is the storage of hydrogen, using lightweight tanks of relatively high density. That is why, a focus of scientists has been put on the use of carbon-based materials and graphene as a perspective solution in the field of H2 storage. This review focuses on the comparison of different methods for hydrogen storage, mainly based on the carbon-based materials and focuses on efficiently using graphene and its different forms to serve a purpose in the future H2-based economy.
