Technical Tours

For the Mobility of the future.

At the Innovationhub in Tübingen, DB Energie is testing the future of green mobility by the use of green hydrogen. The goal is to replace diesel traction in regional transport, thereby further reducing carbon emissions in rail transport. During the Technical Tour, you can discover the world's first mobile hydrogen refueling station, which enables quick refueling of fuel cell trains. Green hydrogen is produced directly on-site via electrolysis. The hydrogen obtained in this way is then compressed, stored in a mobile storage tank before being processed and cooled in the DB Refueler trailer ready for trains to refuel. Lower energy consumption and shorter refueling times will be achieved through communication between the train and the refueling station and a temperature-regulated refueling control system. The innovative DB Energie tank station will refuel a hydrogen train in the same time as it would take to refuel a diesel train.
