IS23 - Computational modeling for hydrogen technologies

E. Martínez-Pañeda (Imperial College London, United Kingdom) and F. Aldakheel (Leibniz Universität Hannover, Germany)
Hydrogen has been hailed as the energy vector of the future. It can decarbonise many applications and sectors, including some that are known to be particularly difficult to decarbonise, such as steelmaking or aviation. However, this comes with significant safety challenges due to the flammability of hydrogen and its ability to embrittle metals. For example, the deployment of a hydrogen energy infrastructure is compromised by the fact that hydrogen can reduce the fracture toughness, ductility and fatigue crack growth resistance of metals by orders of magnitude. Models are urgently needed to map regimes of operation, assess the efficiency of hydrogen decarbonisation across sectors and enable a safe deployment of a hydrogen energy infrastructure. This mini-symposium is aimed at bringing together computational solid and fluid mechanicians working in hydrogen technologies. This includes scientists working in the areas of: (i) hydrogen embrittlement, (ii) electrolysis, and (iii) hydrogen combustion. From the development of multi-physics (deformation-diffusion-fracture) models for predicting hydrogen assisted fracture to recent progress in understanding and simulating hydrogen combustion
