Orlen rozpoczął testy lokomotywy napędzanej wodorem, kupionej od Pesy. To pierwszy taki pojazd w Polsce. Do 20230 roku paliwowy gigant planuje przeznaczyć 7,4 mld zł na inwestycje w technologie oparte na odnawialnych źródłach energii.
First hydrogen locomotive started working in Poland.
Real answer: it’s actually a lot of logistics and technical challenge to bring overhead lines to the whole of eve a small country like England. A lot of these tracks are in regions where there’s no power lines nearby. You still want the trains to go to and through these places.
That’s logic comparing the economic costs of diesel to electric. If you compare the economics with hydrogen, it makes much more sense to run the wire with the track, independent of the availability of electricity.
Hydrogen could be used as a bridge gap measure. It’s relatively easy to move diesel engines to hydrogen. And hydrogen production, even when using gas, is still better than diesel engines.
Maybe at the train track end. But creating the hydrogen and the needed infrastructure for both the creation and distribution, plus the enormous amounts of energy wasted in the production, is unlikely to be more cost effective than the investment in electrifying existing railroads.
But how about replacing the diesel with fucking electrified rail network?
Because now you have to build an electrified track infrastructure in instead of using an already built railway track.
cough overhead lines cough
Jeez if only smart people thought of that.

Just put lines above the track…
Sometimes building infrastructure is more expensive than a hydrogen-powered train. I guess.

It never is, and won’t be until we essentially have free energy. Any serious economic study has concluded as much.
No especially not in the long run and especially especially not regarding efficiency
