The transport turnaround requires new mobility concepts and alternative propulsion technologies, for which a new infrastructure will be necessary. Seventy hydrogen filling stations have already been built in Germany. Even though some of these are located in metropolitan areas, the small number of fuel cell cars means that there are hardly any points of contact between the technology and the population. The filling station infrastructure offers a present interface between hydrogen and society.

The entry of the Coradia iLint could be delayed.
The entry of the Coradia iLint could be delayed.

The success story of fuel cell trains to date is currently undergoing a severe setback: As the Kieler Nachrichten (news) recently reported, electric trains could roll through Schleswig-Holstein from 2022, but they are likely to be equipped with accumulators for energy storage and not with hydrogen.

Fuel cells on rails are not only talked about in the north. Numerous municipalities and regions have meanwhile turned their attention to this promising form of propulsion. The most advanced up to now is Hesse, where Germany’s first serious thought had been given to FC trains and 27 H2 drive units have now been ordered following a successful tender.

Letter to the editor from Klaus Lehmeyer
With great interest I read your article “The search for alternatives in the heating sector” in the H2-international issue January 2019.

I have had a fuel cell heating system for almost a year now. I spent quite some time looking for a new heating system for my building (built in 1955). As a certified energy consultant and efficiency expert, I have not made the task easy for myself.

Effect of hydrogen on materials

Effect of hydrogen on materials

Stress-strain curves of hollow samples filled with hydrogen or nitrogen, with an internal pressure of 70 bar, tested at a draw-off rate of 3.5 µm/min.

Atomic hydrogen partly diffuses into materials during production and operation. If this results in degradation of the material properties, the term hydrogen embrittlement is used. The Fraunhofer IWM has set itself the task of better understanding and mastering such chemical processes and their consequences. For this purpose, a new laboratory for material qualification for hydrogen applications has now been set up.
