Clad pipes for safe and effective hydrogen storage and transport – 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.
