On top of the transportation element, Deutsche Bahn is also looking to develop and test hydrogen train infrastructure. To that end, it’s refitting one of its maintenance facilities to serve as a fueling and maintenance station for the train.

The company plans to create hydrogen by electrolysis, using electricity to split water into oxygen and hydrogen. While that process is fully green (depending on the source of the electricity), it’s highly inefficient compared to modern BEV (battery electric vehicle) technology. It’s also costly to transport and store hydrogen.

Still, hydrogen trains have been successfully tested and are gaining traction quickly
