Canalisations revêtues pour un stockage et un transport sûrs et efficaces de l'hydrogène – CladPipe4H2

The overall aim of the project CladPipe4H2 is the development, manufacturing and testing of new metallic structural material combinations for safe and effective hydrogen storage, transportation and distribution. In the project, material combinations will be developed and manufactured consisting of a base material to meet the strength requirements and a clad material to fulfil the hydrogen barrier and embrittlement resistance requirements. The main goal of the project is to provide durable structural materials and components for stationary (e.g. power production, machinery, residential and industrial use) and mobile (e.g. road, off-road, rail, ship, and aviation) high-pressure gaseous hydrogen applications (= 300 bar). Focus use cases are vessels as well as pipelines and piping for gaseous hydrogen storage and transport being exposed to these high pressures and a large number of load cycles. Due to combination of two metallic materials, costs will be saved by reducing wall thickness compared to monolithic metallic components and by substituting expensive fiber-reinforced polymers. The microstructure and their interaction with hydrogen as well as the influence on the mechanical properties will be investigated. Energy- and cost-effective process routes for small batch size and high volume production will be realized and the manufactured components will be validated with developed testing methods.
As production of green hydrogen is connected with decentralized renewable energy availability, transport, storage and distribution of H2 is major challenge for energy transition. New and cost-effective technologies and components for high-pressure hydrogen applications will make a significant contribution to hydrogen implementation and integration and thus to clean energy transition. This will lead to a noteworthy reduction in CO2 emissions by 2030.
