Clean Technica: In September of 2018, two hydrogen passenger trains started operating on a 100-kilometer (62 mile) stretch of track between the towns and cities of Cuxhaven, Bremerhaven, Bremervoerde, and Buxtehude in northern Germany.
The bright blue trains manufactured by the French company Alstom warmed the hearts of hydrogen die-hards globally. It’s the first commercial hydrogen-powered train in operation, after all. They hope it’s the first of many. It’s a faint hope, but hydrogen might become one of the fuels for a subset of passenger and freight trains in the future, along with line-side electric, battery electric, and biodiesel.
