Hydrogen is considered as one of the most promising sources due to the fact that its earth reserves are practically inexhaustible, and its extraction is possible with the use of various technological methods, including the creation and operation of nuclear-industrial complexes based on high-temperature gas-cooled reactors, as well as using the energy generated by operating nuclear power plants. For the use of hydrogen on an industrial scale, materials capable of storing and releasing hydrogen in significant quantities should be created. Our research is aimed at creating solid-state structures that can accumulate large amounts of hydrogen. The report formulates the basic principles for the formation of (V, Ti, Mg)Nx porous nanocrystalline hydrogen storages using ion-beam assisted deposition (IBAD-method). The data of electron microscopic studies demonstrate the structures of thin films at all stages of their growth: from 5 nm to 1 ?m. It is considered how the bombardment with gas ions during the film deposition contributes to the formation of intergranular nanopores. It is shown that nanoporous (V, Ti, Mg)Nx films can absorb hydrogen in an amount up to 8 wt.% and release it in the temperature range of 50-275°C. The conducted studies showed that investigated materials due to the presence of open nanoporosity are susceptible to atmospheric effects and have to be protected by the thin films up to 100 nm thick. The report provides the rationale that the transition from the simple vanadium, titanium and magnesium hydrides to their complex hydrides containing nitrogen, leads to a significant improvement of the gravimetric, thermodynamic and kinetic characteristics.
