· JVASP-52912· Mg2NiH4

Mg2NiH4 is a magnesium-nickel metal hydride compound that belongs to the intermetallic hydride family, combining lightweight magnesium with nickel to form a hydrogen-storage material. This is primarily a research and development material studied for hydrogen storage applications, where it functions as a solid-state hydrogen carrier offering potential advantages in energy density and safety compared to conventional gas or liquid hydrogen storage systems. Engineers evaluate this compound for next-generation energy storage solutions, particularly in fuel cell vehicles and renewable energy systems where compact, safe hydrogen storage is critical.
