PRESLHY_D6.2_3.0_finalversion

This document provides easy to use guidelines to engineers for the safe design and operation of liquid hydrogen (LH2) infrastructure.
The PRESLHY project is a pre-normative project investigating knowledge gaps related to the use of liquid hydrogen in new applications. Three main topics were addressed:
 Cryogenic hydrogen release and dispersion,
 Ignition of cryogenic hydrogen mixtures,
 Combustion of cryogenic hydrogen.
These topics were studied through:
 A review of the existing state of the art and a ranking of the identified phenomena,
 A large experimental program covering the prioritized phenomena,
 The evaluation and validation of analytical and numerical approaches to assess these phenomena.
General rules, best practices and new means to assess the consequences of LH2 releases are proposed in this document. They will be extracted and expressed in concise language to be used as recommendations for RCS.
