Pr2 H2

Pr₂H₂ is a rare-earth metal hydride compound combining praseodymium with hydrogen, belonging to the family of lanthanide hydrides used primarily in hydrogen storage and materials research. This material is of significant interest in advanced energy applications and is primarily explored in academic and emerging industrial contexts rather than established high-volume manufacturing, with potential relevance to hydrogen economy technologies and specialized metallurgical processing where hydrogen interaction with rare earths is engineered.
