EV-based road transportation is not viable

<< < (208/236) > >>

Haenk:
Just received a notification by "Deutsche Bahn" (german railroad quasi-monopol company).
They are notifying me of some maintenance going to happen soon (there is a single track about 100m away) - they are actually installing charge infrastructure for electric trains.
The idea is to have battery powered trains, using quick charge on a couple of track segments (like 5km length each) and in stations.

On battery, these trains will go up to 140km/h and have a range of 150km max. (probably not both features at the same time).

Your (absent) maths is crap, at $1.50 per litre (pure tax) and 7l/100km would be 10.5c/km.... what production car runs along at 2l/100km????

Here is a map with taxes. Average seems to be 0.5-0.6 EUR/l plus VAT which is on top of this and double taxed, but whatever. That would place it around 3.5 cent/km range for petrol with 7l/100km consumption. The 3c/km for electric cars is quite reasonable IMHO. That would be around 20c/KWh.

Or people claiming it is an anti-EV tax... In reality, the costs of BEVs have dropped quite significantly so subsidies in the form of tax cuts are no longer necessary.

I never seen things happen here all of the sudden, there are always intermediate periods. Compare this to living in an autocratic hellhole, and suddenly realize it's very nice here.

Battery-electric trains surprise me.  I know that they're being trialled at the UK at some point for rural rail electrification, but I would have thought that the cost of the infrastructure for such trains, whilst of course not trivial, would be quickly paid off compared to using reasonably large battery packs on the train (wear and tear, extra mass, purchase cost etc.)   A bit "penny wise pound foolish".  That said one of the biggest issues with rail electrification is that you need to close sections of line for days or weeks at a time to do the work and unlike the road network, the rail network in this country has very little redundancy, so it might be the case that it's just so much more expensive to do the upgrades that batteries make sense, at least in the medium term.

Also I would have thought if hydrogen did have an application then train power would be a pretty good one - size of batteries vs a large hydrogen tank in place of diesel engine - but tank then needs to be sufficient to run for at least a significant part of the journey if the assumption is refilling hydrogen at a train station is not safe enough or too inconvenient.  (Diesel trains aren't refuelled at stations, either.)

Liquid hydrogen being transported on trains through towns? Of course that's nothing like vinyl chloride and phosgene in Ohio or (more photogenically) the Hindenberg, is it?

The optics matter.

Marco:
Diesel burns too, I doubt people would care that much. They're used to it.

Now Ammonia, those accidents are something special.
