The eXtremeMAT-H2 consortium, led by the National Energy Technology Laboratory (NETL), recently convened with an advisory board to deliberate on advancing alloys capable of withstanding long-term exposure to hydrogen at elevated temperatures. The meeting aimed to address materials-related challenges associated with hydrogen utilization in various industries like power generation, transportation, and industrial heating, critical for achieving net-zero greenhouse gas emissions by 2050. Discussions emphasized the significance of understanding the impact of hydrogen on alloy performance at high temperatures, a crucial factor often overlooked in current research. Industry stakeholders provided valuable feedback on research direction and emphasized the necessity of designing reliable alloys for hydrogen systems to facilitate the transition to clean energy. The consortium's use of computational tools accelerates the development of cost-effective alloys, enabling the creation of durable materials for extreme environments efficiently. By focusing on the alloy chemistry, microstructure, and properties in hydrogen, the consortium aims to enhance predictive capabilities and design components resistant to failure in hydrogen-containing environments. The collaboration between industry representatives, leading national laboratories, and research organizations underscores the collective effort to advance materials science for the clean energy transition.
