SrAl2H2
metal· JVASP-85702· SrAl2H2
SrAl2H2 is a strontium aluminium hydride intermetallic compound that belongs to the metal hydride family, synthesized primarily for hydrogen storage and energy applications research. This experimental material is investigated as a potential solid-state hydrogen storage medium and as a precursor for lightweight metal-matrix composites, offering advantages over conventional hydrides through improved thermal stability and reversible hydrogen absorption characteristics. While not yet commercially deployed at scale, materials in this compound class are pursued for next-generation energy storage systems and aerospace weight-reduction strategies where reversible hydrogen uptake is valuable.
