Germany rolls out world's first hydrogen train

Germany on Monday rolled out the world's first hydrogen-powered train, signalling the start of a push to challenge the might of polluting diesel trains with costlier but more eco-friendly technology.

Two bright blue Coradia iLint trains, built by French TGV-maker Alstom, began running a 100-kilometre route between the towns and cities of Cuxhaven, Bremerhaven, Bremervoerde and Buxtehude in northern Germany -- a stretch normally plied by diesel trains.

"The world's first hydrogen train is entering into commercial service and is ready for serial production," Alstom CEO Henri Poupart-Lafarge said at an unveiling ceremony in Bremervoerde, the station where the trains will be refuelled with hydrogen.

Alstom has said it plans to deliver another 14 of the zero-emissions trains to Lower Saxony state by 2021, with other German states also expressing an interest.

Hydrogen trains are equipped with fuel cells that produce electricity through a combination of hydrogen and oxygen, a process that leaves steam and water as the only emissions.

Excess energy is stored in ion lithium batteries on board the train.

The Coradia iLint trains can run for around 1,000 kilometres on a single tank of hydrogen, similar to the range of diesel trains.

Alstom is betting on the technology as a greener, quieter alternative to diesel on non-electrified railway lines -- an attractive prospect to many German cities scrambling to combat air pollution.

"Sure, buying a hydrogen train is somewhat more expensive than a diesel train, but it is cheaper to run," Stefan Schrank, the project's manager at Alstom, told AFP.

Other countries are also looking into hydrogen trains, Alstom said, including Britain, the Netherlands, Denmark, Norway, Italy and Canada.

In France, the government has already said it wants the first hydrogen train to be on the rails by 2022.

Hydrogen trains are all dependent on electricity to perform electrolysis to produce the hydrogen in the first place.  It is much more efficient to run the trains directly from electricity.

Sure, hydrogen only "stores" electricity, but the hydrogen can be produced at times of electricity surplus, while the direct running on electricity requires a steady supply.

How does it work



The rail industry has a problem: Its infrastructure is decades, sometimes centuries old, and it is hugely expensive to upgrade. Diesel-powered trains dominate, but fuel is getting pricey, the trains are noisy and they're terrible for the environment. French multinational Alstom believes it has the solution: a hydrogen-powered train that can be swapped in for its diesel equivalent.

Diesel trains have been used for the better part of a century on pretty much every railway of note because they're very cheap. Moves to add electric power to railway lines have taken place, but it's hugely expensive: Alstom puts the figure at €1.2 million per 1 km, or $1.4 million per 0.6 miles. Of course, these days, most governments simply can't afford to bankroll large-scale electrification.

Battery-electric trains, too, are out of the question, thanks to the sheer size, weight and cost of a battery that could run for 1,000 km on a charge. Hydrogen as a fuel, on the other hand, behaves pretty much like diesel, has a much higher energy density and it only takes 15 minutes to refuel a tank. And on trains, where weight and aerodynamics are less of an issue, you can add more tanks depending on your needs.

From the outside, you certainly wouldn't have guessed that the Coradia iLint is a hydrogen train, looking just like its diesel-powered predecessor. But when it rolls up to approach you, you'll notice how deathly quiet it is: Aside from a little whine from the engine, you'll barely hear it. In fact, the squeak of the wheels against the cold morning tracks were louder than the train itself. Only the air brakes, which are as noisy here as on every other train, are noticeable.

The train looks and feels like pretty much .... engadget.com

Hydrogen production is a dirty business: https://en.m.wikipedia.org/wiki/Hydrogen_production#Steam_reforming

Hydrogen trains are just a political boondoggle.  They are uneconomic and are not green.

Nan, please give me an uptick for that grouch.

please mr.tum try to stay on track...we don't want you going off the rails...whatever your views are
take care back soon another 2 days my weeks ban ends   :cheers
ignorance does not help your post one bit but it probably says an awful lot about you.
