Ensuring their sustainable and safe use in hydrogen technologies is a key factor in the ramp-up of the hydrogen economy. This requires extensive materials qualification, however, most of the accepted; and standardized test methods for determining the influence of gaseous hydrogen on metallic materials describe complex and costly procedures that are only available to a very limited extent worldwide. The hollow specimen technique is a simple, rapid, and economical method designed to overcome the limitations of the current methods for the qualification of metallic materials under high-pressure hydrogen gas. However, this technique is not yet standardized. The TransHyDE-H2Hohlzug project is presented in this article, along with the main steps required to optimize the hollow specimen technique. This includes closing knowledge gaps related to the specimen geometry, surface quality, and gas purity in dedicated working packages, thus contributing to a comprehensive standardization of the technique for tests in high-pressure hydrogen gas.

It involves the production, storage, transport and use of large quantities of hydrogen in existing and new infrastructures. Components along this supply chain, such as pipelines and storage tanks, are made of various metallic materials, with steel being the most common construction material. The rapid introduction of hydrogen therefore brings with it major challenges, in particular the need for comprehensive qualification of components and materials to ensure the sustainable and safe use of hydrogen technologies. This article provides an overview of the state of the art in the testing of materials and components as well as corresponding future trends and developments for a successful transition to a hydrogen economy.
