And 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.
- _hypx 3y agoThe same rules apply for smaller pipelines. It's highly likely that it is cheaper to build hydrogen stations fed by pipelines than high-power cables for DC fast charging. Trucks can work as last-mile distribution too. This is not nearly as big as a problem as critics think, since those trucks only move short distances.
- Turskarama 3y agoWell then, I encourage you to rip out all the copper cables from your house and replace them with hydrogen safe alloy pipes. Put a hydrogen generator and compressor on the curb to feed the whole thing and replace each wall socket with a fuel cell to generate electricity to run your appliances. I'm sure you'll save thousands.
- erik_seaberg 3y agoIsn’t embrittlement still an open problem for high pressure hydrogen pipelines?
- _hypx 3y agoNo. Embrittlement is easily solved by choosing the right alloy, or coating everything with a protective coating.

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.
