Successful test run for worlds first zero-emission hydrogen-powered fuel cell passenger train



Alstom has run the first successful test of the world’s only hydrogen fuel cell passenger train Coradia iLint at its test track in Salzgitter, in preparation for an extensive test campaign in Germany and Czech Republic in the coming months.

The test runs, which will continue for the next four weeks, aim to confirm the stability of the train’s energy supply system based on co-ordinated interaction between the drive, the fuel cell and battery, as well as to check the braking power of the vehicle.

The zero-emission silent train is powered by a single hydrogen fuel cell, producing electrical power for the traction.

Alstom described the Coradia iLint’s design as a “combination of different innovative elements: a clean energy conversion, flexible energy storage in batteries, and a smart management of the traction power and available energy”, as well as “particularly suited for operation on non-electrified networks”...snip more: http://www.railtechnologymagazine.com/The-Sleepers-Daily-Blog/successful-test-run-for-worlds-first-hydrogen-powered-passenger-train

1. Is the power used to isolate the hydrogen from a zero-emission source e.g. hydroelectric or nuclear?

If not, then it's not really a zero-emission train.

2. that's the aprt that always kills me...

these methods end up using MORE energy. Any time you convert stored energy form one form to another there is loss through inefficiency. It takes electricity to process hydrogen.. lots of it.
Idiots, the lot of them.
I'm not in any way against researching ways to accomplish it or more efficient ways, etc, hell, it shoul dbe encouraged.... but building off of known flawed models just seems like nothing more than a greenie circle jerk, and an outright waste of money and resources.

5. Hydrogen not only has to be isolated, it also has to be chilled and compressed...

...which obviously takes even more energy. Transporting it takes yet more energy.

9. Transporting H2

That's the thing about hydrogen- anyone with water and electricity can make it, anywhere, anytime. So it doesn't need a lot of transportation.

It's the perfect decentralized green solution.

10. Whether or not hydrogen is actually "green" depends on how the power to isolate it is produced.

And if you have a "green" source of electric power, is it not more efficient to simply run machinery on that (when possible, as it is with everything except road vehicles and flying machines) rather than go through a conversion process?

6. Hydroelectric, nuclear, or solar

We should be building nuke plants as well as spreading solar - perhaps with some or a lot of solar, use the energy close by to split water (with catalysts). Next gen nuke plants would be good, plus we should fund fusion research.

8. Source of H2

The hydrogen used for the test runs is the by-product of an industrial process, which is reasonably reused as a waste product. In the long term, Alstom aims to support the hydrogen production from wind energy. http://www.alstom.com/press-centre/2017/03/alstoms-hydrogen-train-coradia-ilint-first-successful-run-at-80-kmh/

California's hydrogen stations are mandated to get 1/3 of the H2 from renewable sources.

One of the companies involved is named "True Zero"

True believers in the movement toward a zero emission future, True Zero is creating a network of hydrogen charging ports for the next generation of electric vehicles powered by fuel cells. True Zero is dedicated to providing customers access to safe and reliable retail hydrogen, to enable the widespread adoption of electric fuel cell vehicles...

...We aim to drive a revolution in transportation and energy use by creating a hydrogen economy. Currently, two-thirds of TrueZero’s hydrogen comes from fossil fuels and one-third from renewable bio-mass. In time, that ratio will improve.

4. Not the point

the point is that it makes environmentalists feel good that they are able to stand next to this train and breath deep the clean air of hydrogen power. Good thing the train does not run by the power plant that burns coal or oil to power the Hydrogen plant.

7. My point exactly.
