Im Rahmen des 6. Lausitzer Netzwerktreffens DurcH2atmen hat die BAM das Kompetenzzentrum H2Safety sowie aktuell drei große Projekte zur Schaffung einer Testinfrastruktur auf dem BAM TTS vorgestellt. Es handelt sich hierbei um die vom BMWK geförderten Projekte ModuH2Pipe (Modulare Pipelineanlage zur Untersuchung sicherheitstechnischer Fragestellungen beim Transport von Wasserstoff und Wasserstoff/Erdgasgemischen in Pipeline) und QI Digital "Usecase" Wasserstofftankstelle" sowie den Aufbau einer Höchstdruckinfrastruktur für die Bereitstellung von 1000 bar Wasserstoff in einem 5 m³-Behälter inkl. Peripherie.
Beim BAM-UBA-Behördenerfahrungsaustausch 2022 hat die BAM zu dem Schwerpunktthema Wasserstoff den von der Bundesregierung avisierten Markthochlauf und das Thema Vertrauen durch Sicherheit vorgestellt. Dabei wurde das Kompetenzzentrum H2Safety mit seinen derzeitigen Aktivitäten ebenso vorgestellt wie sicherheitstechnische Fragestellungen, die über die Wertschöpfungskette hinweg derzeit existieren. Dabei handelt es sich um Fragestellungen zur Materialeignung und -kompatibilität, Leckageüberwachung, Schutzkonzepte und Unfallszenarien. Darüber hinaus gibt es Themen, die keinen direkten Bezug zur Sicherheit haben, aber das Vertaruen in Wasserstofftechnologien deutlich fördern können. Neben Aus- und Weiterbildungskonzepten wurden auch die Themen Akzeptanz und Risikokommunikation sowie Normung und Standardisierung behandelt.
In this talk, general aspects of the safety and acceptance of hydrogen technologies were presented. How can trust in new technologies be built when past accidents led to myths and fairy tales? The presentation does away with general prejudices and shows that handling hydrogen is neither more unsafe nor safer than handling other fuel gases. The basis for the safe handling of hydrogen is always a risk analysis.
The Konrad Adenauer Foundation
and the Delegation of German Business in Nigeria is conducting a "Nigeria Hydrogen Future Webinar Series". The fourth event was held under the title "Safe and Sustainable Hydrogen Production in Nigeria". BAM respectively the Competence Centre H2Safety@BAM was invited to present an overview lecture on hydrogen safety and future challenges with regard to safety-related issues. The lecture formed the core of the webinbar along with two other presentations.
Germany has concluded energy partnerships with various countries, including Japan. During the 3rd meeting of the Hydrogen Working Group, the strategic approach of both countries on developments of hydrogen guidelines, certification and safety was presented and discussed. BAM gave a presentation on important topics in the field of safety research and on safety-related issues along the value chain. Furthermore, the work program and selected projects of the competence center H2Safety@BAM were presented.
A safe supply of energy is a fundamental prerequisite for modern industrial societies. The extent to which the energy turnaround is being shaped in Germany in terms of, for example, energy policy, promotion, but also social development was discussed during the 12th Wildau Science Week. BAM contributed to the topic of safety of energy sources and presented the competence center H2Safety@BAM.
The hydrogen tightness of high-pressure hydrogen storage is a Basic criterion for long-term storage. The H2 permeation coefficients of epoxy resin and a glass lacquer were determined to enable the geometric optimization of a glass capillary storage. It was found that the curing conditions have no significant influence on the H2 permeation coefficient of resin.
The H2 permeation coefficient of epoxy resin is only about three orders of Magnitude greater than that of borosilicate glass. This suggests that the initial pressure of 700 bar takes about 2.5 years to be halved in capillary array storage. Therefore, a high-pressure hydrogen storage tank based on glass capillaries is ideally suited for long-term storage in mobile applications.
