Gas hydrates are a promising method for hydrogen storage due to their ability to trap hydrogen molecules within water-based cages. This review article discusses the current state of research on using gas hydrates for hydrogen storage, highlighting the challenges and potential solutions. While early studies focused on storing pure hydrogen, recent research has explored modifying formation conditions and using promoters to enhance storage capacity and formation rates. Thermodynamic promoters, such as Tetrahydrofuran (THF), Cyclopentane (CP), and 1,3-dioxolane, have been used to achieve moderate hydrate-forming conditions, although they can reduce available space for hydrogen storage. To address this, researchers have proposed using sub-stoichiometric concentrations of thermodynamic promoters to increase hydrogen storage capacity. Kinetic promoters, such as surfactants and porous materials, have also been investigated to accelerate hydrate formation. The use of these promoters can significantly improve the efficiency of hydrogen storage. However, the high pressures and low temperatures required for pure hydrogen hydrate formation remain a challenge. To overcome this, researchers are exploring ways to lower the required pressure and raise the required temperature for hydrate-based hydrogen storage. The review also discusses the potential of gas hydrates for sustainable energy, emphasizing their environmental benefits and the need for further research to enhance their practicality for large-scale applications. Overall, gas hydrates show great promise as a viable solution for hydrogen storage, but more research is needed to overcome the current challenges and improve their efficiency and practicality.Gas hydrates are a promising method for hydrogen storage due to their ability to trap hydrogen molecules within water-based cages.
