The aim of the HyTunnel-CS project is to perform pre-normative research for safety of hydrogen driven vehicles and transport through tunnels and similar confined spaces (FCH-04-1-2018). The main ambition is to facilitate hydrogen vehicles entering underground traffic systems at risk below or the same as for fossil fuel transport. The specific objectives are: critical analysis of effectiveness of conventional safety measures for hydrogen incidents; generation of unique experimental data using the best European hydrogen safety research facilities and three real tunnels; understanding of relevant physics to underpin the advancement of hydrogen safety engineering; innovative explosion and fire prevention and mitigation strategies; new validated CFD and FE models for consequences analysis; new engineering correlations for novel quantitative risk assessment methodology tailored for tunnels and underground parking; harmonised recommendations for intervention strategies and tactics for first responders; recommendations for inherently safer use of hydrogen vehicles in underground transportation systems; recommendations for RCS. The objectives will be achieved by conducting inter-disciplinary and inter-sectoral research by a carefully built consortium of academia, emergency services, research and standard development organisations, who have extensive experience from work on hydrogen safety and safety in tunnels and other confined spaces. The complementarities and synergies of theoretical, numerical and experimental research will be used to close knowledge gaps and resolve technological bottlenecks in safe use of hydrogen in confined spaces. The project outcomes will be reflected in appropriate recommendations, models and correlations could be directly implemented in relevant RCS (UN GTR#13, ISO/TC 197, CEN/CLC/TC 6, etc.). HyTunnel-CS will reduce over-conservatism, increase efficiency of installed safety equipment and systems to save costs of underground traffic systems.

The aim of the HyResponder project is to develop and implement a sustainable trainer the trainer programme in hydrogen safety for responders throughout Europe, supporting the commercialisation of hydrogen and fuel cell technologies by informing responders involved in the permitting process, improving resilience and preparedness, and ensuring appropriate accident management and recovery. The specific objectives of the project include the development of clear and updated operational, virtual reality, and educational training for trainers of responders to reflect the state-of-the-art in hydrogen safety. The European Emergency Response Guide for responders will be revised to reflect advancements. The materials will incorporate identified intervention strategies and tactics for liquefied hydrogen applications. A Pan-European Network of responder trainers will be established and trainers from at least 10 European countries will attend a bespoke course in hydrogen safety pertinent to responders. Using feedback from the network on national specificities, educational training materials will be adapted where required to reflect regional peculiarities. The materials for responders will be translated and made available in 8 languages via an e-Platform. The translated materials will be utilised by the newly trained trainers to deliver workshops in 10 countries across Europe enhancing the reach and impact of the programme. National Training Clusters will be developed to consolidate links between the hydrogen safety and responder communities and to support the delivery of workshops at a national level. Through the establishment of an International e-forum for responders, and the integration of the translated materials in the e-Platform, it is anticipated that a sustainable pan-European training programme in hydrogen safety for responders will be developed, which will be recognised as the standard in hydrogen safety training across Europe.
