Germany has launched the world’s first hydrogen-powered train fleet.

Germany has inaugurated a railway line powered entirely by hydrogen, a “world premiere” and a significant step forward for green train transport despite nagging supply challenges.

A fleet of 14 trains provided by French industrial giant Alstom to the German state of Lower Saxony has replaced diesel locomotives on the 100km (60 miles) of track connecting the cities of Cuxhaven, Bremerhaven, Bremervoerde and Buxtehude near Hamburg“We are very proud to put this technology into operation together with our strong partners as a world premiere,” Alstom CEO Henri Poupart-Lafarge said in a statement on Wednesday.

Hydrogen trains have become a promising way to decarbonise the rail sector and replace climate-warming diesel, which still powers 20 percent of journeys in Germany.

Billed as a “zero emission” mode of transport, the trains mix hydrogen on board with oxygen present in the ambient air, thanks to a fuel cell installed in the roof. This produces the electricity needed to pull the train.

Regional rail operator LNVG said the fleet, which cost 93 million euros ($93m), would prevent 4,400 tonnes of CO2 being released into the atmosphere each year.

Run for its money
Designed in the southern French town of Tarbes and assembled in Salzgitter in central Germany, Alstom’s trains – called Coradia iLint – are trailblazers in the sector.

The project created jobs for up to 80 employees in the two countries, according to Alstom.

Commercial trials have been carried out since 2018 on the line with two hydrogen trains but now the entire fleet is adopting the groundbreaking technology.

The French group has inked four contracts for several dozen trains between Germany, France and Italy, with no sign of demand waning.
