Safety of cryogenic hydrogen transfer technologies in public areas for mobile application

The risk management aspects concerning the transfers of LH₂ are critical and need to be technically addressed to provide a solid basis for future standardisation and safety regulation. The project should provide practical outputs (as safe procedures and installation/implantation rules) based on the current LH₂ hazards knowledge available and/or developed in previous projects, such us the FCH 2 JU PRESLHY and HyResponder projects[[https://www.clean-hydrogen.europa.eu/projects-repository_en]] for instance.

Proposals should:

• Define at least, but not limited to, 3 applications related to hydrogen mobility involving LH₂ transfer such as filling a stationary tank, bunkering of ships or refuelling a truck;
• Define the LH₂ transfer devices (hoses, vents) and operational conditions (mass flow rate, temperature, pressure);
• Perform a risk analysis of the operations for each application including the definition of the accidental scenarios, their quantification in frequencies and consequences;
• Propose safety barriers, suitable hazard zoning strategies and separation distances and validate their efficiency;
• Analyse the possible hazards and risks of co-activities and simultaneous operations and determine, if needed, additional validated barriers and separation distances;
• Disseminate risk-based recommendations and guidelines on LH₂ transferring facilities;
• Develop and disseminate consensual loading procedures (hose connection & disconnection, purging, grounding, instrumentation, certification of personnel) for LH₂ transferring operations;
• Provide science-based recommendations, guidelines and procedures to the concerned industry groups and standardisation committees.

Proposals should identify and target the relevant standard(s) at the scope and activities should envisage links and synergies with existing platforms and/or projects on LH₂ as well as means of collaboration with similar activities ongoing internationally. Proposals are encouraged to include a formal standardisation body within the consortium.

Proposals are expected to contribute towards the activities of Mission Innovation 2.0 - Clean Hydrogen Mission. Cooperation with entities from Clean Hydrogen Mission member countries, which are neither EU Member States nor Horizon Europe Associated countries, is encouraged (see section 2.2.6.8 International Cooperation).

The conditions related to this topic are provided in the chapter 2.2.3.2 of the Clean Hydrogen JU 2022 Annual Work Plan and in the General Annexes to the Horizon Europe Work Programme 2021–2022 which apply mutatis mutandis.
