Hydrogen-resistant metals to reshape the energy landscape

Hydrogen has the potential to become a game-changer in the current energy landscape, helping to reach UK’s 2050 net-zero target. Unfortunately, safety is one of the main barriers preventing a wider uptake of hydrogen as an energy carrier: hydrogen exposure significantly degrades the mechanical properties of structural metals, triggering the catastrophic failure of big components. Therefore, as the first step to developing hydrogen-resistant materials, there is a need to understand the complex interplay between hydrogen and the microstructure of materials. Along this talk, we will explore the complex, but fascinating world, of hydrogen-material interactions, including the effects of hydrogen on plasticity, the influence of hydrogen in the mechanical properties of additively manufactured metals and the cutting-edge techniques used in our lab to characterize hydrogen diffusion in the metal. Finally, we will discuss possible avenues to mitigate hydrogen embrittlement and develop hydrogen-immune alloys. Biography: Alfredo Zafra is a senior postdoctoral researcher on hydrogen embrittlement and environment-assisted cracking in the "Hydrogen embrittlement and SCC testing lab", at the Department of Engineering Science, University of Oxford. Before this, he was a research associate in the Department of Civil and Environmental Engineering at Imperial College London (2021-2023) and a graduate researcher at the University of Oviedo, where he obtained his PhD in Materials Science in 2021. During this time, he has contributed to understanding hydrogen-material interactions in steels and additively manufactured alloys. He is currently dedicated to developing a new generation of hydrogen-resistant metals using advanced manufacturing techniques, including additive manufacturing and nanofabrication.
