Publishable Short Summary The project PRESLHY had it’s 3rd project meeting in Bergen, Norway, hosted by HySafe member Gexcon. The place was selected, because it allowed to have a joint workshop with the Norwegian project SH2IFT, which also has a focus on liquid hydrogen and a work package on BLEVE events, which is complementary to the PRESLHY experimental program.
Besides the progress report of each work package a workshop on measurement technologies for flow and concentration measurements was organised.

Agenda of the Meeting
Remark: On Wednesday 6th March 2019 before the actual PRESLHY Meeting, it was agreed to have a Joint Workshop with the Norwegian SH2IFT project. At this workshop PRESLHY in general and details of the WP3,4,5 and 6 were presented. More than 60 persons took part in this workshop, which was also driven by a strong interest of the Norwegian maritime industry in LH2 safety issues. The detailed agenda and presentations may be inspected on https://www.sintef.no/en/events/hydrogen-safety-liquid-hydrogen-workshop/

7th March 2019 09:00 – 12:30
Welcome to the Measurement Workshop “Concentration and Flow Velocities” – Thomas Jordan (KIT)
TJ welcomed the participants also in behalf of the local host Gexcon, representing HySafe. He
informed about the history and intent of the measurement workshops, which were initiated by the
NoE HySafe and then organised by the HySafe work package 2 leader Ernie Reinecke (Jülich/HySafe).
Ernie Reinecke could not organise this workshop, but might take the initiative again for the next
workshops to be organised in combination with the next project meetings. There have been
investigations whether these highly valuable workshops might receive some extra funding via
national programs, the German NIP/NOW for instance.
The focus of this workshop was on the experimental measurement of concentration and flow
velocities at cryogenic conditions.
All presentations, besides the one of KHI, are available from the website
https://preslhy.eu/meetings/3rd-workshop-concentration-and-flow-measurement-techniques/
Know Good Practice for Flow Measurement at Pro-Science – Andreas Friedrich (PS) AF presented an overview on velocity and mass flux measurement technologies and respective applications in the KIT laboratories. For most applications severe limitations for low temperature measurement have been identified.
KHI representatives initiated a discussion about the availability of Coriolis mass flux measurement for large scale. TS reported on bi-directional flowmeters used by other research groups.
Experience at HSE – Jonathan Hall (HSE) JH presented the experience gained with the past LH2 experiments at HSE. He reported strong fluctuations observed in LN2 and LNG spill test, which might be associated with the special set-up of the experiments.
The actual mass flux values for the published trailer discharge experiments, have been values determined by the supplier BOC without actual measurement.
For the PRESLHY experiments a Coriolis device will be used. However, the calibration to low temperatures is non-trivial because of the dependency of the elastic modulus on the temperature.
Experience at SNL – Ethan Hecht (SNL) EH explained the SNL facility for cryo-jet experiments and the temperature measurement (Si diode) used for the LHe cooled hydrogen jet releases. The published results, which are used for a benchmarking exercise in WP3, have been discussed. A discussion about some ice formation at the release nozzle started.
T. Jordan, KIT 8 Draft MoM GM03 V190321 (D1.5)
For the ignited jet tests a Nd:YAG laser was used for ignition. The focus had to be located on a zone with about 11-12% vol H2 concentration to initiate an ignition successfully.
EH showed plans for large scale experiments and wide area monitoring wrt cryo-releases.
General experience with low T measurement at USN – Knut Vagsaether (USN) KV presented experiments of a rapid depressurisation of liquid CO2. The results of the experiments could be made dimensionless and than applied to LH2 by material scaling. The result of this could be used for modelling of the initial part of a LH2 BLEVE event.
Flow Measurment at KHI – Kiyotaka Bito (KHI) Experiments with an articulated LH2 loading arm were presented. KB showed phenomena induced by an emergency blowdown of the inventory contained in the transfer line.
KHI performed experiments, where LNG and LH2 were released from mid-scaled buckets and spilled on the ground. The observation of the clouds of condensed humidity revealed a quite buoyant behaviour of the cold gases generated in the LH2 spills whereas the clouds generated by the LNG spills were sticking close to the ground level.
Finally, KB showed experiments, measurements respectively, highlighting the thermal stratification in large LH2 cryostats above the gas/liquid interface.
7th March 2019 13:30 – 17:30
WP1 – Thomas Jordan (KIT)
TJ welcomed all participants to the General PRESLHY meeting.
The protocol of the previous General meeting in Saclay as well as the agenda for the actual meeting were approved.
TJ reported the current status of the project. He confirmed that the CA is still awaiting signing by the KIT legal officer.
PRESLHY has succeeded in initiating an ISO (TC 197) Preliminary Working Item PWI with the number 24077 and with the title “Safe Use of LH2 in Non-Industrial Settings”. Project leader is by information via email dated 15 January 2019 Thomas Jordan.
A consequence/ risk assessment benchmark for a LH2 based HFS was suggested by AL and distributed via email (see WP2 below). It was agreed that in the first step the catastrophic scenarios should be kept included for the consequence analysis part and results of the first phase, the determination of separation distances, shall not be published. The reason for this decision is, that for the catastrophic cases the separation distances might be quite large and misinterpreted by not-involved persons. The results of the second phase, consisting of a risk analysis, might be treated in a different way.
T. Jordan, KIT 9 Draft MoM GM03 V190321 (D1.5)
The experimental program at KIT is delayed by 3-4 months. The reasons for this delay are:
- Late changes in the experimental requirements, leading to the need for an additional experimental facility to be designed and built ( CRYOVESSEL).
- Delayed delivery of components (e.g. cryo-valves, pressure transducers, etc)
However, the warm DISCHA tests have been conducted as a set of reference tests. The LN2 cooled variant will be conducted in March. The CRYOVESSEL flange is under construction. Requirements for temperature measurement and level meters and investigations for existing equipment are on the way.
The INERIS experiments on ignition are also delayed because of problems with the experimental set-up. However, a large fraction of the promised work was done and was presented in WP4.
The deliverable D17 summarizing the updated experimental program is under review and will be soon uploaded.
The Annual Data Reporting D9 is waiting for the corresponding request of the FCH 2 JU PO.
TJ repeated the decision for using the KITopen system for FAIR data management and the agreed formats and processes in this regard. Some selected data sets from the “warm” DISCHA tests will be used for a prototypical first data reporting.
For the ICHS2019 conference in September 9 abstracts (out of ~150) are dealing with cryo- or liquid hydrogen. The majority of authors was present at the meeting. The paper presenting PRESLHY is under preparation. The deadline for delivery is 31 March. TJ will negotiate a delayed submission of the full paper to include as much as possible fresh information from the experiments.
See https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP1_20190307_PRESLHY_Intro_Jordan.pdf for the respective presentation.
WP2 – Laurence Bernard (AL)
LB presented details of the suggested benchmark (see https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP2_PRESLHY_LHRS-Consequence-Analysis-1.pdf ).
General Assembly – Thomas Jordan (KIT)
The proposal for two new members in the Advisory Council:
- Michael Johnson, DNVGL - Jens Franzen, Daimler
was supported unanimously.
TJ welcomed the new members of the Advisory Council.

8th March 2019 09:00- – 14:30
WP3 – Alexandros Venetsanos (NCSRD)
AV presented the ongoing and planned modelling activities and deliverables of the work package.
NCSRD contributions to WP3 He showed results of the NCSRD release modelling of Hecht experiments (2018). For the 2 phase chocked release he compared HEM, HRM and DEM Od model results. HEM underestimates, HRM and DEM conservatively overestimate release rates. Additionally he showed first results of a 1d simulation applying the Possible-Impossible Flow (PIF) model.
For further details see https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP3_GA_WP3_060318.pdf or in the respective meeting page of the PRESLHY website.
UU contributions to WP3 DC showed results of the UU modelling work. The notional nozzle concept was applied to the SNL tests and the measured and calculated mass fluxes fit almost perfectly. Similarly the concentration decay in the center line adheres to the classical correlations. For the relative low pressure levels the influence of the selected equation of state is negligible. This might become more important with the KIT release tests reaching 200 bar. The CFD simulations of the unignited jet with P=2bar, T=61K and d=1.25mm show good agreement with the experimental data. For further details see https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP3_190308-PRESLHY-project-meeting-WP3-UU-update.pdf or on the respective meeting page of the PRESLHY website.
AL contributions to WP3 EV presented CFD results of the SNL release tests. Air Liquide is using the FLACS code for these simulations. For the 2 bar case the results seem to be reasonably reproducing the experimental outcome. However, strong deviations have been observed for the slightly higher pressure experiments with 3 bar. Possible reasons were discussed. The compressibility effects were discarded and it was suggested that this deviation might be attributed to jet instabilities, possibly supported by the ice formation at the nozzle. EH was commenting the T and mass flow measurements and admitted that there is a considerable uncertainty. For further details see https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP3_AL_2019_03_08_CFD_Meeting_PRESLHY_Bergen.pdf or on the respective meeting page of the PRESLHY website.
UWAR contributions to WP3 JW presented the planning for the UWAR contributions, which will focus on OpenFOAM with HRM and VOF models; see https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP3_Warwick.pdf or on the respective meeting page of the PRESLHY website.
Pro-Science contributions to WP3 Finally AF of Pro-Science showed the current status of the experiments planned for the release and mixing phenomena by PS. As mentioned in the introduction by TJ, the “warm” DISCHA tests had been conducted. AF showed a few BOS snapshots and reported on the difficulties with the fast T measurement inside the pressure container. For more details see https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP3_20190308-PSFriedrich.pdf.
T. Jordan, KIT 11 Draft MoM GM03 V190321 (D1.5)
WP4 –Jonathan Hall (HSL)
JH gave an updated overview on the ignition work package (see https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP4_update_08032019_v1.pdf or on the respective meeting page).
INERIS experimental contributions to WP4 CP gave a detailed presentation on the status of the INERIS contributions. This included an update on the experimental results for determination of the MIE and ignition by hot surfaces. In his presentation he touched upon the theoretical framework anchoring the work in the general landscape of the complex ignition phenomena. The MIE set-up had to be renewed and is actually supported by industry. The hot surface ignition tests are based on mixing H2, O2 and LN2. Under certain conditions and low temperatures (T_min about -150°C) of the premixed system a flash back from the hot coil was observed. For a few cases even detonations were observed. However, the influence of the H2 concentration on the ignition temperature was marginal. The temperature at which ignition on the hot surface was observed was always about 620°C. The presentation of CP https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP4_PRESLHY_ppt-WP4-INERIS_07_03_19.pdf is accessible via the meeting website.
UU modelling contributions to WP4 DC explain the CFD modeling of spark ignition. CP commented that there might be a strong impact of the electromagnetic phenomena influencing the partially ionised kernels. For details see the central WP4 presentation of JH, which includes the contributions of UU.
WP5 – Mike Kuznetsov (KIT)
MK presented the planned simulation and experimental program and pointed out the differences of ignited and unignited jets. For the high pressure, large orifice (i.e. 4 mm diameter) DISCHA experiments in principle a two phase release is expected. He presented the state-of-the-art scaling rules for jet fire flame lengths and radiation characteristics.
He reported on the status of the construction of the CRYOTUBE experiments and the principles for the pool fire, as well as for the congested/confined HSE experiments. He pointed out, that measurements of expansion ratio and detonation cell size values are lacking and it was commented that – if possible - flammability and laminar flame speed measurements should considered additionally.
For details see https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP5_PRESLHY_KIT_Bergen_20190308.pdf on the meeting website.
WP6 – Donatella Cirrone (UU)
DC presented the status of the work package WP6. She explained the ToC of the LH2 “chapter” in the HySafe Handbook of Hydrogen Safety. Frank Markert will take over responsibility for the further processing. All members are invited to contribute. However, the lead author Karl Verfondern has to agree to those contributions. A short discussion on terminology was initiated by a small inconsistency with regard to “liquid” and “cryogenic” hydrogen.
T. Jordan, KIT 12 Draft MoM GM03 V190321 (D1.5)
Furthermore DC showed the current list of engineering models. She invited all partners again to suggest further models and to support the collection. She closed her presentation with a short outlook on the dissemination conference, which might be combined again with a SH2IFT meeting.
For details see https://hysafe.info/wp-content/uploads/sites/3/2019/03/WP6_PRESLHY_UU_Bergen_190305.pdf on the meeting website.
