A German research team says that demand for iridium, lanthanum and nickel could weigh on the growth of the global hydrogen-powered aviation market. Leibniz Universität Hannover researchers have studied the feasibility of widespread hydrogen-powered aviation. They identified global concern for iridium demand, particularly if proton exchange membrane water electrolysis (PEMWE) catalysts are heavily used. In addition, limitations in renewable energy sources and water availability could emerge regionally. The study suggests that addressing these challenges, such as developing PGM-free catalysts for ...Den vollständigen Artikel lesen ...
