Safety – hydrogen fuel cell explosion risk assessment

We have considerable experience of explosion risk assessments from our work in the offshore gas industry and addressed this challenge in three parts. Firstly, we used chemical equilibrium modelling to establish the peak deflagration and detonation pressures for a range of internal leak and ignition scenarios. We then applied these pressure to a model of the vessel to determine whether it would fail. Finally, we used a missile fragment energy assessment method from the nuclear energy to establish whether these fragments would pierce the outer containment.
