· JVASP-53811· SrMg2FeH8

SrMg2FeH8 is an experimental metal hydride compound combining strontium, magnesium, iron, and hydrogen. This material belongs to the complex metal hydride family, which is primarily investigated for hydrogen storage, thermal management, and advanced energy applications where reversible hydrogen uptake/release is desirable. While not yet in widespread industrial use, materials in this class are of significant research interest for next-generation energy systems where conventional metals and alloys cannot meet performance requirements.
