While hydrogen in the maritime sector has only ever been treated as an option for the future under “far away” for years, not only the events at which this energy source is the subject of lively debate are currently on the increase, but also the reports on concrete projects. More and more shipping companies are turning to hydrogen because the pressure to say goodbye to fossil solutions is growing from all sides.

There is a lot going on in the energy sector at the moment. As a result of numerous activities and events – be it diesel scandals or CO2 pricing, driving bans or Fridays-for-Future demonstrations, flight shame or real laboratories – more and more players are committing themselves to more sustainability as well as to hydrogen as an energy storage.

Green hydrogen, preferably produced by electrolysis, links the energy, industry and mobility sectors and is an important tool to enable the integration of renewable energies. Proton exchange membrane electrolysis (PEMEL) is considered the most promising technology due to its power density and dynamics.

Synthetic gases will play an important role in the full supply of renewable energies for Germany’s energy requirements. The meta-analysis of [1] shows that, according to several studies, an electrolysis capacity of more than 100 GW is required in the future energy system in Germany. If such an electrolysis capacity is to be installed in the course of the next few decades, it will be necessary to ramp up the market in good time so that market-driven, reliable and inexpensive plants can be made available.
