The main advantages of hydrogen are, among others, the local generation using renewable energies, transportability and energy storage. Compared to the concept of direct power generation as well as distribution, hydrogen can theoretically be transported and distributed via the existing gas grid. However, the existing pipelines used in the transmission network are susceptible to hydrogen corrosion, which increases brittleness and, thus, reduces service life.
For the application of the existing pipeline infrastructure to transport 100% hydrogen, the DAP chair develops an internal coating by means of EHLA within the framework of the Zukunftscluster Wasserstoff.
With this process, dense and metallurgically bonded coatings can be produced, making this the ideal technology for producing gas-tight coatings.
