· JVASP-50950· Y2MgNi2

Y2MgNi2 is an intermetallic compound containing yttrium, magnesium, and nickel, belonging to the rare-earth metal hydride storage alloy family. This material is primarily investigated for hydrogen storage and energy applications, where it functions as a reversible hydrogen absorber-desorber for fuel cell systems and clean energy storage. While not yet widely deployed in production engineering, Y2MgNi2-based alloys are researched as alternatives to conventional nickel-metal hydride batteries and hydrogen storage media, offering potential advantages in volumetric hydrogen capacity and thermodynamic properties compared to simpler binary systems.
