The mechanisms used for storage range from simple compression, absorption, and liquefaction to physical trapping of the hydrogen. These hydrogen storage technologies use different physical phenomena and mechanisms to store hydrogen and offer different storage capacities. Some of the most common hydrogen storage technologies include high-pressure gas tanks, metal hydrides, cryo-compressed hydrogen storage, porous materials, and hydrogen hydrates. Research on the storage of hydrogen can be divided into two categories: hydrogen storage in onboard fuel cell vehicles and large-scale stationary hydrogen storage. Therefore, one of the most crucial aspects in the development of hydrogen energy as a sustainable energy source is its storage. Depending on the application and use of hydrogen energy, it may pass through various supply chain links. It has also been predicted that, by 2050, hydrogen fuel will meet 25% of the energy demand in the transportation industry. Hydrogen fuel could meet 10% of the global demand for building heating by the year 2050. ![]() The existing infrastructure would not require any major changes for the use of hydrogen. Another advantage of using hydrogen is that it can easily replace natural gas for building heating purposes. Hydrogen has very high fuel efficiency in comparison to conventional fuels, with a calorific value of 141.7 MJ/Kg. Hydrogen gas is considered green fuel if its production does not involve the emission of carbon dioxide, i.e., if the energy utilized to produce hydrogen is produced using renewable sources. Green hydrogen gas is recognized as the most favorable substitute for fossil fuels. Hydrogen is at the forefront in the current transitioning phase and represents the next sustainable fuel. These energy sources can be used to produce fuel, such as hydrogen. The storage of these types of energy is also a major challenge. However, the major drawback associated with these energy sources is that they cannot be directly utilized as fuel in most applications. Geothermal energy, solar energy, ocean wave energy, hydropower, and nuclear energy have been employed successfully in a variety of applications. The future of renewable energy sources depends on the efficient storage of hydrogen fuel. However, all these types of hydrogen fuel face a single major common problem, which is their easy, safe, and cost-effective storage. Depending on the method of production, hydrogen fuel can be broadly classified as green, blue, or brown hydrogen. Hydrogen fuel production and storage represent one of the most prominent research topics at present. ![]() ![]() This review article provides summarized information for readers about the different promoters tested and their benefits and shortcomings. The hydrate promoters are classed according to the structure of the hydrate crystals they form, i.e., sI, sII, sH, and semi-clathrate hydrate. This review aims to present a comprehensive summary of the different hydrate promoters that have been tested specifically in terms of hydrogen storage. Through the use of efficient, economical, and green promoter molecules, hydrogen hydrate can be used to store large amounts of hydrogen economically and safely. Solving the problems of extreme pressure and temperature through the use of promoter molecules would make these materials a promising storage medium with high potential. One of the major challenges when storing hydrogen in hydrate crystals is the extreme pressure and temperature conditions required for the formation of hydrogen hydrates. The benefits of hydrates, such as reversible formation and dissociation, their environmentally friendly nature, economical costs, and lower fire risk, make them one of the most promising hydrogen storage materials. Clathrate and semi-clathrate hydrates have recently been gaining major interest as hydrogen storage material.
