The killer feature of BEVs is that you never actually have to take them somewhere to charge if you're charging them at home. It's only on long trips that you need to stop.
If you're doing hundreds of km multiple days per week then Hydrogen might make sense, but I'd say that's a vanishingly small percentage of the population. Given that Hydrogen is also _always_ going to cost more than direct electricity, I don't think it's ever going to be mainstream.
- _hypx 3y agoAnd if you don't have a home with a garage to charge your car? How do apartment dwellers charge their car? And the rest of your post is bullshit. You want a centralized system that can meet all refueling needs by itself. And as we make hydrogen from excess green electricity, it will drop to nearly nothing in terms of cost. Anti-hydrogen rhetoric is a repeat of anti-wind and anti-solar rhetoric of the past.
- Turskarama 3y agoThe cost of generating the hydrogen is only one part of it. We need the electricity grid anyway, and bolstering it is already a necessary part of a 100% green grid. If we want to use Hydrogen for vehicles then that means constructing an entire second distribution system. Even if you use trucks, we will need to build thousands of trucks with Hydrogen tanks (which are much harder to make than regular pressure vessels, by the way) in order to distribute it. All this, and you think adding chargers to apartment complexes is too hard?
- _hypx 3y agoWe will need hydrogen anyways too. Not unless you think all of industry doesn't need to exist. Hydrogen can be delivered via pipeline just like natural gas. It is actually cheaper to move hydrogen around than electricity this way.
- Turskarama 3y agoExcept this can largely be handled by building industry which requires Hydrogen near to where the Hydrogen is generated. It can be done in large central facilities and requires _minimal_ movement of the Hydrogen itself. It's really not the same thing as a distribution system that needs to go essentially everywhere.
- _hypx 3y agoExcept you wouldn't build it like that. Even "on the spot" production will still significant hydrogen storage and distribution. It's not like you can place a giant tank right next to each piece of machinery. This are still going to be miles of piping. And it is cheaper to move hydrogen than electricity. People have an inverted understanding of the problem.
- Turskarama 3y agoMiles of piping is still less than hundreds of miles of piping. > And it is cheaper to move hydrogen than electricity Citation needed. Probably true across oceans, overland I'm doubtful.

It is far cheaper to move fuel via pipelines than electrical wires. Your entire argument is just based on BEV propaganda. It is going to be systematically cheaper to go with hydrogen infrastructure than an all-electricity solution.
- Turskarama 3y agoThat's bulk transmission, not distribution.

If an idea is obviously better, and improves life for the majority of people but sometimes brings new issues, then throw the whole thing out. It's a weird kind of technology conservatism that I am truly surprised to see here on HN, but I do keep seeing it, about all kinds of things.
