Most of the rail networks across Europe depend on detrimental diesel oils to operate, with more than 4,000 cars in the German state alone.
And because there are no immediate plans to switch over to electrical alternatives Alstom Transport are taking the initiative to make the move over to sustainable travel.
The French multinational have just unveiled a zero-emissions train – a world first.
The Coradia iLint will be powered by lithium ion batteries which obtain their power from a hydrogen fuel cell situated on the roof of the train.
It can travel almost 500 miles a day at speeds of up to 87mph, boasting low levels of noise which come from its wheels and subsequent air resistance.
And due to the nature of burning hydrogen its only emissions are steam and condensed water.
“Alstom is proud to launch a breakthrough innovation in the field of clean transportation on regional trains," Alstom Chairman and CEO Henri Poupart-Lafarge writes.
Tests are expected to start in December and 14 of the trains have already been scheduled to start in Lower Saxony – the fourth most populated region of Germany.
Since the Coradia iLint was announced at the InnoTrans trade show in Berlin interest has also been shown in Norway, Denmark and the Netherlands.
But this isn't a brand new idea. NASA have been using liquid hydrogen (as it produces mass amounts of energy when burned with oxygen) to launch rockets into space since the 1970s.
When you see massive clouds erupting from shuttle take-offs chances are this isn't smoke, but steam.
