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.
Biodiesels arent more efficent, a huge waste of land and destroying the local environment through monocultures, pesticides and fertilizers.
The most reasonable solution would be to fucking electrify the train tracks. It is a train god dammit. It runs on tracks and the track aint running anywhere else.
Biodiesels are still better than diesel and the stuff can be manufactured from seaweed, algae, any biomass really. It doesn’t have to be a monoculture. It doesn’t even have to be 100% biodiesel either - start blending it in. I agree electric motors and electrification are the ultimate outcome but the rail industry has a lot of lines and a lot of locomotives and and you want progression over time with options for battery, power lines or diesel, potentially all 3 on the same line in different parts. It might take decades to transition. It’s certainly not hydrogen, that’s for sure.
In support of your point, and to help clarify it, there’s a lot of train lines where the cost (and the carbon output) of electrification is far beyond the benefit. A lot of the North Wales coast, for example, because working in the tunnels would be prohibitively expensive. In these cases it makes sense to have bi/trimodal trains, at least until electrification technology makes significant breakthroughs.
Another example might be cases where an old rail line (e.g. ex-mining) is looking at being reopened at a low capacity. It would be madness to immediately electrify. An example I have looked at was running a train for tourists on what is currently a little-used freight line (that still uses tokens!) in the Lake District.
A whole lot of misinformation about biofuel here. Manufacturing biofuels does not require significant changes to current agriculture practices. Most biofuel is made from byproducts that would be burned as waste otherwise.
Two things: We’re already talking apples and oranges because I’m talking about biofuel production in the United States (the world’s largest producer of biofuel) and you’re talking about Europe.
Secondly, I’m talking about increasing the production of second-generation biofuels (cellulosic biofuel) which can be made from byproducts and green waste.
I am in favor of electrifying transportation networks in ways that do not require battery energy storage. However, no discussion about reducing reliance on fossil fuels, in particular when it comes to personal transportation, is honest if it does not account for the incredible environmental damage caused by the extraction of materials for and manufacturing and disposal of lithium batteries. Hydrogen power isn’t a direct burning of hydrogen as a clean fuel, it works by generating electricity to charge lithium batteries, which are then discharged to power electric motors.
Additionally, there is not enough lithium in the earth to sustainably replace carbon fuels for transportation. Renewable biofuels, combined with a reduction or cessation of the use of fossil fuels and an increase in clean nuclear energy are a much more likely and rational solution for the transportation energy problem.
I fail to see the problem? Freight trains in Europe regularly run electrical already. There is no technological reason as to ehy they shouldnt or couldnt be electrified.

That is wrong already. Land use for biofuels
But it would get even worse, when we’d expand the land use even further by raising the demand significantly.

I can appreciate the electrification push for passenger vehicles. Good luck moving frieght with electric.

And if you want to go to mountain area, then electric is your only option
RTFM. EMUs are more capable than DMUs.
