PRESLHY activities have carried out analytical work, numerical simulations, and experimental testing in order to increase the current knowledge on aspects related to the safety of LH2 and supporting the development of international standards.

Main achievements

• thorough analysis of the current safety-related knowledge about the transport, use, and storage of LH2, given priority to the most relevant aspects that need to be addressed for safer use of LH2
• development and validation of engineering tools and CFD models addressing three safety-related areas: 1) cryogenic hydrogen release and dispersion 2) ignition of cryogenic hydrogen mixtures, 3) combustion of cryogenic hydrogen
• gaining insights into the behaviour of LH2 in high-risk situations and provision of real data for the validation of the tools and models
• chapter on LH2 safety in the Handbook of Hydrogen Safety of the International association HYSAFE
• guidelines for the safe design and operation of LH2 infrastructure
• supporting the development of international regulations, codes and standards on LH2
