Passengers in Europe may soon be commuting on the world's first zero-emissions train.
French engineering giant Alstom is building a passenger train powered by hydrogen fuel cells and lithium-ion batteries. The train won't emit any greenhouse gases just clean steam.
Alstom's hydrogen-powered passenger train.
Alstom said its hydrogen-powered Coradia iLint trains could be running on German railroads as early as December 2017. The goal is to steadily replace Europe's diesel-powered trains, which spew toxic soot and carbon dioxide into the air...snip
Both hydrogen fuel cells and lithium-ion batteries have been greeted with some skepticism in the transportation sector. Hydrogen is an extremely flammable gas, and some electronics with lithium-ion batteries have famously caught on fire. (Does Samsung's Galaxy Note7 ring a bell?)
But manufacturers of hydrogen-powered cars, such as Toyota and Honda, say their vehicles are actually safer than petroleum-fueled cars, since hydrogen quickly dissipates in the atmosphere once released from the tank. Gasoline, by contrast, leaks and pools, creating a larger source for prolonged burns...snip

World's first zero-emission hydrogen train to begin operations in Germany
The world's first hydrogen powered, emission-free train is set to go into service in Germany in 2017 -- a ground-breaking innovation that could signal the phasing out of heavily polluting, diesel-powered trains...

Where does a battery only electric train get its juice? Most likely from a coal fired power plant. Shifting the pollution source may make people feel good but that's all it does.

There are already lots of zero-emission trains which go much faster than that.

(14,047 posts)It takes energy the break water into hydrogen and oxygen. If you are using solar, wind or other non emitting system, then the claim is reasonable. If you are burning coal or gas in the process, you are simply polluting from another source. The same applies to electric trains.

ETA, but even with the standard grid mix, the straight electric is most certainly cleaner since the round trip penalty for hydrogen is so high. The best onboard fuel would be biodiesel.
