The CO2 savings potential of converting shunting locomotives from diesel to hydrogen drive is huge. There are around 1,000 diesel shunting locomotives in use in Germany and around 4,000 across Europe. The average service life of a diesel shunting locomotive is 50 to 70 years and it emits around 150 tonnes of CO2 per year. The conversion of the shunting locomotive to a hydrogen drive is one of them and is of course something very special with a world premiere. Alstom, global leader in smart sustainable mobility solutions, today completed the world’s first journey with a shunting locomotive converted from diesel to hydrogen drive in Salzgitter, Germany.
