Components for Energy Carriers
Division 9.1
The ‘Components for Energy Carriers’ division deals with the safety and qualification of components for alternative energy carriers, with a particular focus on hydrogen and its derivatives, such as ammonia.
The division focuses on technical and scientific questions regarding material compatibility for the components of these energy carriers. This involves not only the development of suitable test methods, e.g. hollow tensile specimen testing technology, but also the analysis of corresponding materials and welds.
The services and expertise of the division are bundled in the competence centre H2Safety@BAM in the competence field of material properties and compatibility for hydrogen technologies.
