Как правило, hydrogen stored in a liquefied, absorbed or compressed gaseous state. The main problems that need to be solved in the development of hydrogen storage technologies are related to ensuring their profitability and safety, which is directly related to the chemical and physical properties of hydrogen. The most promising method is considered to be the storage of hydrogen in an absorbed state. Most materials allow sorption of no more than 7-8% hydrogen by mass fraction.
Hydrogen and hydrogen-containing mixtures are considered as promising fuels for transport. For the large-scale use of hydrogen, it is necessary to solve the problems associated with its transportation. Hydrogen can be transported to the place of use in a gaseous or liquid state, as well as using solid or liquid carriers containing hydrogen in bound form.
