It has long been understood that hydrogen has a negative effect on metals like iron and steel. Studying this phenomenon is not easy because of the fact that hydrogen is everywhere, is extremely small and is in constant motion. In this video, MARÍA JAZMIN DUARTE CORREA explains how new technologies can help to pin down the impact of hydrogen in this context. Focusing on the particular challenges involved in studying diffusible hydrogen, Duarte explains how nano indentation can be used to specifically identify its effects. Looking forward, the research seeks to support the development of materials that are resistant to deformation caused by hydrogen. This has particular relevance for the energy sector where the storage and transportation of hydrogen presents a pressing challenge.
