A team from TU Graz has analysed the risk and damage potential of hydrogen vehicles in tunnels and derived recommendations. Their conclusion? Any damage would be extensive, but its occurrence is unlikely.
In addition to electric vehicles, hydrogen-powered vehicles are also seen as an alternative to conventionally powered vehicles. However, an increase in the number of such cars with fuel cells (fuel cell electric vehicles – FCEVs) would also result in completely new hazard scenarios, especially in tunnels. In the HyTRA project, Graz University of Technology (TU Graz) has investigated what types of incidents involving hydrogen-powered vehicles in tunnels are realistic, what dangers arise for people and the tunnel structure, and what measures can be taken to minimise these risks. The project was funded by the Austrian Research Promotion Agency (FFG), the Federal Ministry for Climate Protection, Environment, Energy, Mobility,…
