There are plenty of applications where batteries simply won’t be sufficient, so synthetic fuels do have a place. Just not in land based transport.
Agreed. Or the heating of buildings and warm water. (edit: would also be very! inefficient)
Maybe in some remote, off-grid cabins, otherwise heating with synthetic fuels would be hugely inefficient.
I’d really be interested to see a comparison between the costs of electrifying the rail network vs using synthetic diesel for freight throughout the US.
Unlike cars or semi trucks, diesel-electric locomotives are extremely efficient. On the other hand, electrifying the many thousands of miles of track that run through large, unpopulated areas of the US seems like a monumental challenge that would yield far fewer benefits over electrifying cars.
trains are actually one of the examples where you can get away with lower energy dense fuels, like methanol, ammonia or even compressed hydrogen. sure the range will go down, but for many connections this will not matter that much because it will still be possible to go 1000km with one tank if needed.
It worked on every other continent. Of course it would be harder to do in the US because they’ve neglected building out their railways for so long. But the Chinese built a high speed rail network in a few years. There’s no practical reason why the US wouldn’t be able to do it.
Is agriculture land based transport? Short of an actual nuclear tractor, nothing but diesel has the energy density sufficient to run modern scale farms.
Chatting around the fire we’ve tried to imagine a solution like dragging a cable but with tractors pushing close to 1000HP now that’s about a megawatt. That’s a long, fat cable or an extremely dangerous voltage to drag around a field, probably both. And an insane grid infrastructure to get power to the field borders.
You wouldn’t believe how much fuel goes into agriculture, to the point where I believe it makes up nearly a third of emissions (possibly including land clearing, can’t remember the details). Synthetic fuels are the only net-zero option.
Well I’m kind of a fan of the nuclear tractor honestly but I kind of doubt it :)
