CaAlH

CaAlH is a calcium aluminium hydride compound belonging to the metal hydride family, which represents an emerging class of lightweight materials under investigation for hydrogen storage and advanced energy applications. This material is primarily of research interest rather than established in widespread industrial use; it is studied in the context of solid-state hydrogen storage systems and potential use in next-generation energy systems where reversible hydrogen absorption and release are critical. The compound's notably low density and hydride chemistry make it a candidate for applications demanding compact energy storage, though its practical deployment remains largely in the development and materials characterization phase.
