Fuel Cell Trains
Fuel cells to switch trains onto a greener track.
If railways are to help cut carbon emissions they need to find a less polluting alternative to diesel.
Much of Japan's rail system is electrified, but for those routes still running diesel-electric locomotives the NE-train is coming. The diesel generator is replaced with two 65 Kw Hydrogen powered fuel cells and a hydrogen tank to power the motors to a speed of 65 kmph and it stores regenerative braking energy in batteries.

“Running on hydrogen, plus oxygen from the air, the train will emit just a few puffs of steam”

Pollution/Carbon emissions? Only if the electricity used to make the hydrogen is from a polluting source such as coal.
Economists have suggested that fuel cell trains are vital to reducing dependence upon oil and combating climate change.
