It looks like the sort of standard diesel train youd find on commuter lines and in rural areas that rail electrification hasnt reached.
But here in Germany, they’ve developed one of the worlds first trains to run on hydrogen fuel cells.
This is how it works.
Hydrogen from an on-board tank goes to a fuel cell.
That takes in oxygen from the air.
And it creates a chemical reaction to make power.
The first trains ran on coal, of course.
That was filthy.
Diesels still emit gases that harm people and heat the climate, unlike ultra-clean hydrogen.
This is the emission from the exhaust.
You cant smell it.
Im told you cant taste it.
Thats because its water, pure water.
Battery-powered trains have been trialled in the UK and elsewhere as a substitute for overhead power lines.
So whats the advantage for hydrogen?
We are using hydrogen because it gives us a better range for the train during the day than a battery would.
Batteries take longer to charge and give us less energy through the day.
So we would have to recharge them several times to provide the range that we can get with hydrogen.
One 15-minute hydrogen fill-up drives the train for more than 600 miles.
What’s more, hydrogen can be produced by surplus wind power.
Hydrogen trains made here in Germany will go straight into service.
The makers expect good business as governments round the world accept the need to cut emissions to protect the climate.
