First Hydrogen-Powered Trains Rolling in Germany

The world's two first hydrogen-powered trains have begun service in Germany. The trains, which operate in between northern German towns, are a step away from traditional diesel power.

According to a press release from Alstom, the trains' French parent company, they are are "equipped with fuel cells which convert hydrogen and oxygen into electricity, thus eliminating pollutant emissions related to propulsion." The trains, which promise a low-noise trip, can hit speeds up to 140 km/hr, or 86.9 MPH. They'll run on 100 kilometers (62 miles) of track.
