In the reporting period the beneficiaries have initialised the project and installed necessary administrative and management schemes. The required meeting structures and communication channels have been set up. The website has been built to serve as a colaboration platform and repository for all project documents, as a meeting planning tool and provides further means for cooperation. The data management plan has been developed and further iterated to make sure that all generated data of the project will be findable, openly accessible, interoperable and reusable on the long term. This will help to maximise the sustainable impact of the research work executed.
The external network has been activated and further developed. PRESLHY entered in a partnership with the Norwegian project SH2IFT, which has similar objectives for LH2 but a complementary working program. Additionally, the project has been presented to essential members of the external network, the IEA, ISO, EHSP, etc. in the framework of the initial dissemination activities.
In the initial phase the beneficiaries also prepared the scientific and technical basis by working out the state-of-the-art at the beginning of the project. The technical status was captured in two reports, the state-of –the-art report and the installation description, the scientific basis was summarised in 3 separate reports dedicated to the phenomena “release and mixing”, “ignition” and “combustion”. The situation with regard to regulations, codes and standards has been analysed in a special RCS report. The scientific and risk weighted research priorities have been assessed via a PIRT study and a dedicated open work shop “LH2 Research Priorities Workshop, Buxton, UK – 18 September 2018“, involving numerous international external experts. On the basis of this extensive preparatory work the experimental program has been adjusted, further refined and finally started.
In the first 18 months 3 out of 12 experimental series, one for release and two for ignition, have been completed and documented. A subset of the more than 200 tests of the DISCHA release experiment have been published in KITopen and can be accessed freely, worldwide via
https://doi.org/10.5445/IR/1000096833(öffnet in neuem Fenster). For the other 3 scheduled experiments the major preparatory work, consisting of detailed design, purchase and construction, installation of system including set-up of measurement techniques, safety assessments and checks have been successfully done. However, the actual execution of the experiments experienced a certain delay, caused by the late kick-off meeting and by problems in the delivery and construction of special parts required for cryogenic conditions.
The first test results demonstrated by very good reproducibility a high quality in the experimental set-ups and revealed interesting effects regarding hot surface ignition and electrostatic field generation by cryogenic discharges. The scientific exploitation is on its way.
24 common scientific publications have been issued or are in preparation. The project has been presented at 5 conferences, flyers newsletters and posters have been produced and distributed. The project has been listed in H2FC JU Success Stories Report. Two open workshops were organised, the LH2 Research Priorities Workshop in Buxton UK on 18 September 2018, supported by JRC and US DoE, and the HySafe-PRESLHY-SH2IFT- joint workshop for LH2 Safety in Bergen, Norway 6 March 2019 attracting more than 80 participants.
Finally, the PRESLHY project has successfully started potential standardisation work via initiating the Preliminary Working Item PWI ISO/24077 for "Safe Use of Liquid Hydrogen in Non-Industrial Settings" at ISO TC 197 with PRESLHY coordinator as acting PWI manager.
