-- a ground-breaking innovation that could
signal the phasing out of heavily polluting, diesel-powered trains.
The
first "hydrail", or hydrogen-powered train, will begin transporting
passengers on the Buxtehude-Bremervörde-Bremerhaven-Cuxhaven line in
Lower Saxony, in northern Germany, in December 2017,
Although
the first train in operation will only run a short, 60-mile
(96-kilometer) route, four German states have signed an agreement with Alstom, the French company that builds the trains, for the purchase of up to 60 additional locomotives, if they are judged a success.
"Alstom
is proud to launch a breakthrough innovation in the field of clean
transportation," Alstom chairman and CEO, Henri Poupart-Lafarge, said
in a statement.
"It shows our ability to work in close collaboration with our customers and develop a train in only two years."
Quiet revolution
The
new, silent train, called the Coradia iLint, was unveiled by Alstom at a
railway industry trade fair in Berlin earlier this year, and only emits
steam and condensed water.
Although
not suitable for electric railway lines, it's designed to provide a
clean alternative to the large number of heavily polluting diesel trains
that run on non-electric lines throughout Europe.
Germany alone has more than 4,000 diesel-powered train cars, according to Alstom, and about 20% of all of Europe's current rail traffic is hauled by diesel locomotives according to the European Union.
The
train uses the same equipment as a diesel train but runs on an entirely
new technology that uses hydrogen -- a waste product of the chemical
industry -- as the fuel source.
Energy
to power the train is generated by large fuel cells that sits on top of
the train. This cell combines hydrogen with oxygen to produce
electricity, which is then stored in batteries.
Each
two-car train-set requires a fuel cell and a 207 pound (94kg) tank of
hydrogen to supply it, while the oxygen is obtained from the local air.
The train can complete a 500 mile (800 kilometer) journey on a full tank
of hydrogen, which is enough for one day according to Alstom, and
carries up to 300 passengers.
Although
the 87 miles per hour (140 kilometers per hour) speed the train reaches
is far below that of other European trains, such as the German
Inter-city Express and French TGV, it is well suited to the quieter and
shorter stretches of the European rail network that haven't yet been
converted to electricity.
