Which is why h2 is the answer. h2 that is shown to work, regardless of all the hyperbole and reckless claims battery fans make.
There aren't claims, these are physical constraints. For heavy vehicles such as trucks and busses (and trains) there might be a market, provided the H2 is an otherwise unused byproduct of some process and needn't be produced, but for the majority of personal mobility major breakthroughs are required to make it competitive.
So much denial in the anti h2 crowd.
I'm not anti H2, why would I? I'm not part of any crowd. I just did part of my physics training on the subject.
20 years ago, while there were more H2 vehicles on the road, nobody in the H2 storage fields thought it would last. On a basc level, the physics of getting electrons out of a material is better than getting protons out. And then there is an already preexisting infrastructure for free.
The biggest issue is the need to build out an entirely new fueling infrastructure with a highly explosive fuel. EVs can piggyback off of the existing electrical grid.
To replace fossil fuel transport will require an entirely new infrastructure regardless - if it's electric the existing grid will essentially have to be built out by a substantial factor.
A hybrid future is entirely feasible with long established city to city truck transport routes using hydrogen from dedicated planned end points and mid points along with lighter EV vehicles and non standard route EV trucking.
The bigger issue is scaling down cracking stations so you can use stranded electricity from solar and wind to generate the H2.
It’s like saying, “It’s easy to ship fragile glass sculptures. You just smash them into little bits and put the bits in an envelope, I don’t see why people use all that styrofoam.”
You’re obviously not a New Yorker
It's not a problem. At all.
Likewise, “It’s possible to ship and store H2” is not the same thing as “it’s not a problem to ship and store H2”.
It's not a problem. At all.
And nobody said "preventing" adoption, since that's easy to misinterpret.
It's reducing adoption a lot, compared to what it would be if hydrogen was as easy to store as butane or kerosene.
Maybe it took too long, but we've got a single standard for high powered charging going forward, and I think J1772 is universal for PHEVs and slow charging of EVs. Eventually, people running charging networks will figure out how to keep their machines working and add card readers. My favorite broken charger is the wireless ones --- someone has run off with the cable, but hey the advertising display still works.
Not to mention the technical challenges (assume we can handle) of the low volume density, low temperature..
There may well be, we don’t really know because we haven’t been looking for it at any scale.
But outside of that, these things will improve, although your numbers are a bit out there.
For such people, and there's a lot of these people, h2 is less work (quicker fill up) than electric charging.
Right now, electric cars are targeting the wealthy. Wealthy people tend to have houses. That could certainly change, but even if it starts to target those with less fiscal fortitude, many such live in apartments with no charging infrastructure.
What then?
One person in this thread, was talking about cars, with no knowledge or understand that 3 separate manufacturers have h2 products on the market. Not 3 cars. 3 manufacturers. Another was discussing things as if it's an insurmountable task, that having h2 in cars is "really hard", yet these cars are being sold and used all over the world, with loads of adoption in Japan.
People make up weird claims about efficiency. About storage. About where h2 comes from. On and on and on. It's so ... absurd.
This isn't a 'my team your team' thing, yet it seems like, especially americans, are wired this way. "It's not thing $x, thus evil! wrong!! We must, absolutely must destroy any hope of this other thing existing.
h2 is the future for many application and usage spaces, and I can see batteries the same way too. It's not either or, and made up claims won't help the green movement at all.
In contrast, an electric car uses electricity to charge a 99% efficient battery, and discharge to the 90% engine. So, 89% efficiency - much, much better.
