· JVASP-53775· Mg2CoH5

Mg2CoH5 is an intermetallic hydride compound combining magnesium and cobalt with incorporated hydrogen, belonging to the class of metal hydrides and complex intermetallics. This material is primarily of research and development interest rather than established in high-volume production, being studied for hydrogen storage applications and advanced energy conversion systems where the reversible hydrogen uptake/release capability is leveraged. Its potential relevance lies in emerging clean energy technologies where lightweight metal hydrides offer advantages over conventional storage media, though industrial adoption remains limited pending further development of thermal management and cycling stability.
