The presentation starts with the first agreement of making a national attempt for the introduction of a pV-limit for hydrogen transport. It explains aspects of the technical development, provides an impression of catastrophic incidents, and explains the difference between risk control and consequence limitation. Then the process of determining consequences and the result from the discussion at the UN-WG are explained. The next part summarises the approach for counting the number of impacted persons as a function of the model of pressure wave, the pressure peak, the limits of injured persons and the population density. Finally, the latest state of the discussion and the subsequent recommendations for a pV-value and the adequate phrases for explanation are introduced.
Dr Mair presents the competence centre “H2Safety@BAM”. He starts with a spectacular hydrogen accident on the Tempelhofer Feld (Berlin) in 1894, comes to the foundation of the competence centre in the context of the hydrogen strategies of Germany and the EU and explains their safety-focused orientation in order to create and maintain confidence in hydrogen technologies.
Beyond the long-term changes in energy supply, in Sept. 2022 there are enormous cost leaps in gas supply, which puts hydrogen as an energy carrier in a different light.
Based on this, he presents the structure of the Competence Centre with its 5 competence areas and the corresponding contact persons. This is underpinned by a slide on each of the work packages in the fields of competence.
At the end of the presentation, he explains the focus of the competence area "Component Testing, Component Safety and Approval", for which he is responsible. This is the question of cost reduction by using the whole potential of digitalisation in connection with the safety surveillance of the storage systems. The run of a fully digital system is of great importance for both, for the hydrogen supply of large consumers via road and rail and for storage systems in stationary plants. A robust and well-thought-out digitalisation in all levels of documentation will lead to a new quality in monitoring safety porperties, integration of new components and cost reduction.
