“…The equilibrium pressure, itself, depends upon temperature. It increases due to expansion with an increment in temperature (and vice versa) [16]. The volume expansion between the coexisting α-and the β-phase corresponds in many cases 10-20% of the metal lattice.…”

Significant progress in the installation of renewable energy requires the improvement of energy production and storage technologies. Hydrogen energy storage systems based on reversible metal hydride materials can be used as an energy backup system. Metal hydride hydrogen storage systems are distinguished by a high degree of safety of their use, since hydrogen is stored in a solid phase, a high volumetric density of stored hydrogen, and the possibility of long-term storage without losses. A distinctive feature of metal hydride materials is the reversible and selective absorption and release of high-purity hydrogen. This paper presents experimental studies of LaNi5-based metal hydride materials with a useful hydrogen capacity of 1.0–1.3 wt.% H2 with equilibrium pressures of 0.025 - 0.05 MPa and 0.1 - 1.2 MPa at moderate temperatures of 295 - 353 K for the hydrogen purification systems and hydrogen long-term storage systems, respectively. The applicability of metal hydride technologies for renewable energy sources as energy storage systems in the form of hydrogen is also shown.

“…The ability to efficiently store and release hydrogen is of paramount importance for various applications, including hydrogen fuel cells, portable energy systems, and renewable energy storage [2]. Metal hydrides have emerged as a promising class of materials for hydrogen storage due to their high hydrogen content, and reversible hydrogen absorption/desorption capabilities [3]. Nevertheless, the main challenge in developing metal hydrides is the first hydrogenation or so-called "activation" which is quite slow and requires higher temperatures in order to initiate the activation [4].…”

This article presents an investigation into the impact of High Pressure Torsion Extrusion (HPTE) on the microstructural features, hardness and hydrogen storage, focusing on pure magnesium. HPTE is a modern mechanical nanostructuring technique that can refine the microstructural properties and subsequently affects the mechanical and functional properties of the materials. Two HPTE regimes were used in this study: (1) Direct Extrusion without rotation (DE), and (2) an extrusion speed of 6 mm/min along with a rotational speed of 1.8 rpm (v6w1.8). One sample in as-received conditions was also tested as a reference. Results showed increased hardness in the material after HPTE processing, with the DE sample reaching 60 HRB and the v6w1.8 sample exhibiting a gradient distribution of hardness from 71 to 83 HRB. X-ray diffraction analysis revealed significant microstructural refinement in the v6w1.8 sample. Results of hydrogenation kinetics showed that the DE sample absorbed up to 1.2 wt.% of hydrogen, while the v6w1.8 sample displayed 7.2 wt.% of hydrogen absorption, approaching the theoretical hydrogen storage capacity for magnesium (7.6 wt.%). These findings highlight the positive effects of HPTE on microstructural refinement and hydrogen storage, showcasing its potential for advancements in materials science and hydrogen-based energy technologies.

On the example of the alloy Ti 15.4 Zr 30.2 Mn 44 V 5.4 Сr 5 , the technological scheme of producing massive ingots by the technique of induction melting in open Al 2 O 3 crucibles, which can be used in industry, is developed. This scheme ensures the absence of significant interaction between the crucible material and the melt, while maintaining the allowable content of aluminium impurities in the alloy, and thus achieving the required structure, phase composition, and hydrogen storage properties.
