· JVASP-55713· CaMgNiH4

CaMgNiH4 is a complex metal hydride compound containing calcium, magnesium, nickel, and hydrogen, representing an experimental material class rather than an established commercial alloy. Research into this composition is driven by potential hydrogen storage applications, as metal hydrides are studied for energy storage and fuel cell systems where reversible hydrogen absorption/desorption is critical. The material's viability depends on its thermal stability, hydrogen release kinetics, and cyclability—factors that determine whether it could compete with established hydride systems for advanced energy storage or industrial hydrogen applications.
