They enable the large-scale economic transport and storage of energy as well as they represent alternative fuels for energy-intensive mobile applications such as aircrafts, ships and HGVs. For the last one, the number of vehicles and fuel stations has increased rapidly in the last 10 years all over Europe. Does this also entail new risks, for instance from a BLEVE in case of fires? To answer this question, BAM has conducted several research projects over the last decades and intensified the research recently with several experimental, numerical, and empirical outcomes on how a tank with insulation behaves in a fire. The presentation shows an overview of this research. The findings are relevant for global standardization procedures and to improve the overall safety in chemistry and technics.

Paramount to these objectives are reliable quality and safety standards, essential for ensuring supply safety, environmental compatibility, and instilling confidence in these technologies. In the realm of safety management systems, gas sensors emerge as vital components for detecting hydrogen. This presentation delves into the imperative role of hydrogen systems, emphasizing their capability to monitor and control operations, issue warnings, signal hazardous conditions, and sound alarms. It explores the intricate landscape of functional safety considerations and addresses the challenges associated with measurement uncertainty in sensor testing. A diverse array of sensors catering to hydrogen, pressure, temperature, and flow are available, each contributing significantly to the safety and efficiency of hydrogen technologies. Applications are envisaged to adhere meticulously to quality infrastructural regulations, codes, and standards, ensuring seamless integration and operation within the broader hydrogen ecosystem.

Does this also entail new risks for instance from a BLEVE? A key to answer this question is to research representative fires by its characterization and its effect on the insulation. At BAM’s technical test side in Germany, a test series was started to answer this question among others. This paper presents results on a pool fire under a colorimeter, that simulates a tank. The investigation points out, that the full fire characterization approach allows to represent the fire. The findings are relevant for the investigation of a representative design fire that is applicable for the approval and improvement of tanks as well as to research accident scenarios and their consequences.

This includes the implementation of preventive measures as elements of safety management in order to identify and eliminate potential sources of error. In addition, training should be specifically focussed on avoiding errors and the safe use of hydrogen technologies. The principial approach of a gas sensor testing laboratory shows how to ensure reliable results, it is advisable to conduct sensor testing under controlled conditions, focusing on identifying specific properties and quantifying performance criteria. A well thought-out strategy for error prevention makes a significant contribution to preventing accidents and increasing overall safety when using hydrogen.
