The article delves into the critical analysis of strategies for retrieving precious metals from used hydrogen production membranes, particularly focusing on anion exchange membrane water electrolysis (AEMWE) as a sustainable method in aviation fuel production. The study sheds light on the challenge of utilizing Platinum Group Metals and other critical raw materials like Nickel and Cobalt, which are essential for efficient electrocatalysis. These materials are highlighted due to their scarcity and inclusion in the European Union's Critical Raw Materials list. The thesis supervised by Dr. Santiago J. Garcia Espallargas aims to quantify the depletion of Platinum, Nickel, and Cobalt in AEMWE applications for aviation and evaluate various strategies for their recovery. By recommending optimal retrieval methods, the research strives to enhance resource sustainability and facilitate a circular economy approach in the aviation sector. Overall, this study emphasizes the importance of efficient material management to support the long-term viability of hydrogen production for green aviation.
