LH2 airport


To establish hydrogen supply infrastructure at airport, onsite storage is likely to be based on liquid hydrogen. However, liquid hydrogen implies specific hazards and risks, which are very different from those of compressed gaseous hydrogen. The related specific issues, including leaks, fire, and explosion, need to be carefully addressed to ensure higher levels of safety provisions. Warwick FIRE won one grant in the the Transport Research and Innovation Grant (TRIG) competition to evaluate safety zones and mitigation measures for hydrogen refuelling infrastructure at airports using the modified OpenFOAM code developed and validated in her previous EU and EPSRC funded hydrogen projects. The CFD predictions will help to establish the horizontal and vertical extents of the flammable cloud following liquid hydrogen release during aircraft refuelling or catastrophic failure of storage tanks; and quantify the associated fire and explosion hazards associated. The results will be analysed to formulate recommendations for Regulations, Codes and Standards, and mitigation measures.
