Green hydrogen needs secure distribution networks, VDI colloquium on 15.01.2020

With the VDI on site in Bitterfeld-Wolfen on 15.01.2020.

The working group "Energy and Environment" of the VDI Halle district association started with a new management team and the visit of the project HYPOS H2-Netz on 15.01.2020 in Bitterfeld-Wolfen.

In order to achieve the ambitious goals of the energy transition, technologies for the generation, storage and transport of energy must be developed. In addition to the existing natural gas infrastructure, additional supply infrastructures for green hydrogen will also be required. So far, however, there is hardly any experience in the distribution of pure hydrogen. Worldwide, only a few hydrogen pipelines exist, which consist exclusively of steel materials.

On January 15, 2020, the "Energy and Environment" working group of the Halle district association of the Association of German Engineers (VDI) invited participants to visit the "H2-Netz" project at the HYPOS research network in Bitterfeld-Wolfen, where the focus was on the testing of plastic pipelines, their suitability for modern installation methods, the connection and supply of a hydrogen consumer, and the distribution network structure including safety technology. The twenty-eight participants were able to view the installed test technology:

  • In an installed distribution network of plastic pipes, hydrogen is passed through in a partial flow.
  • Various odorization methods are tested in an odorization plant.
  • The measurement of the tightness of the pipes is carried out by means of a permeation measuring chamber.
  • End users such as a fuel cell are tested via an experimental container.

The working group "Environmental Technology" in the VDI Hallescher Bezirksverein thus started with new activities after a longer break and under the name "Energy and Environment". Our employee Dipl.-Ing. Thomas Meier has taken over the leadership of the working group together with Dipl.-Ing. Sigrid Klein. Thus, after a multitude of international activities, GNS is again increasingly involved in Halle.
