The only emissions from the train are steam and condensed water, and noise levels are lower than the equivalent DMU.
Alstom is offering a train-and-maintenance package, as well as the hydrogen infrastructure.
The launch follows the letter-of-intent signed in 2014 with the German states of Lower Saxony, North Rhine-Westphalia, Baden-Württemberg, and Hesse for the use of fuel cells on a emission-free train.
The Coradia iLint is based on the Coradia Lint 54 DMU which has had its diesel engine replaced with a hydrogen fuel cell driver. The trains will be manufactured at Alstom's Salzgitter plant.
