5 PRESLHY Project Review Meeting, 9 September 2019, Brussels, Belgium
D2.1 RCS analysis
▪ Review and analysis of:
− current Regulations, Code and Standards regarding LH2
(NFPA, PGS 35, …)
− Industry best practices for LH2 (EIGA, CGA, …),
− LH2 Accidentology,
− Standards and guidance related to LNG installations.
▪ Conclusion:
− Importance of science-based hazard distances,
− Necessary comparison with RCS requirements.
6 PRESLHY Project Review Meeting, 9 September 2019, Brussels, Belgium
D2.2 State of the art report
▪ Objective: identify knowledge gaps.
▪ Focus on LH2 experimental and modelling work on:
− Release/mixing phenomena,
− Ignition phenomena,
− Combustion phenomena.
7 PRESLHY Project Review Meeting, 9 September 2019, Brussels, Belgium
D2.3 LH2 installation description
▪ Description of LH2 installations for the whole logistic chain:
− Delivery infrastructure,
− Liquefaction plants,
− Stationary large storages,
− LH2 trailers,
− LH2 based fueling station.
8 PRESLHY Project Review Meeting, 9 September 2019, Brussels, Belgium
D2.5 PIRT analysis
▪ PIRT: Phenomena Identification and Ranking Table
▪ Systemic way of gathering information from experts on specific
subjects and ranking the importance of the information, in order to
determine what are the highest priorities for research and
development on that subject.
▪ 3 main sections (as WP)
− WP3 : Release and mixing phenomena (17 Physical Phenomena)
− WP4 : Ignition phenomena (9 PP)
− WP5 : Combustion phenomena (17 PP)
▪ List determined with PRESLHY partners and others persons
of good will (SH2IFT project mainly)
9 PRESLHY Project Review Meeting, 9 September 2019, Brussels, Belgium
D2.5 PIRT analysis
▪ For a list of LH2 physical phenomena, value between 1 and 5
regarding:
− General level of understanding,
− Level of maturity of engineering model,
− Level of maturity of CFD modelling,
− Availability of experimental data,
− Criticality for enabling LH2 in populated areas.
▪ Google Form questionnaire filled by 24 experts (8 nationalities)
▪ Calculation of a Knowledge Score (KS = a * b * c * d)
▪ Calculation of a Global Score (GS = KS / e (criticality) ⇒ Ranking
10 PRESLHY Project Review Meeting, 9 September 2019, Brussels, Belgium
D2.4 LH2 Research Priorities Workshop
▪ Objectives:
− Summarize LH2 state of the art,
− Derive research priorities for the safe use of LH2 in non-
industrial settings.
▪ Presentation of the results of the PIRT,
▪ Discussion around the PIRT results.
▪ Three debated topics:
− BLEVE,
− Material compatibility,
− Jet fires.
11 PRESLHY Project Review Meeting, 9 September 2019, Brussels, Belgium
D2.6 Refined work program
▪ Based on conclusions from state of the art and PIRT, need
for additional research on:
− Physics of liquid releases,
− Electrostatic ignition,
− LH2 / solid O2 ignition,
− Deflagration, detonation and flame acceleration in cold
conditions.
12 PRESLHY Project Review Meeting, 9 September 2019, Brussels, Belgium
D2.7 Consequence analysis benchmark
▪ Based on a typical LH2 filling station layout.
▪ Scenarios and consequence thresholds have been defined
▪ Participants will:
− Describe their model (EM, CFD),
− Calculate hazard distances for each scenarios.
▪ Objective: assess the level of consensus in the different
tools and methods used by risk and safety actors and
comparison with current RCS.

Delays and deviations
▪ All objectives have been reached. However, the execution of
the tasks and the delivery of the reports was delayed, mainly
because of the late Kick-off Meeting and in consequence
also late LH2 Research Priorities Workshop.
▪ No impact on the project execution.
15 PRESLHY Project Review Meeting, 9 September 2019, Brussels, Belgium
Ongoing activities and further planning
▪ Consequence analysis:
− Waiting for additional contributions,
− Treatment and compilation of results,
− Presentation at the meeting in Buxton in November.
