Take it easy, it's a bit more complex than that. Slow as it might be, everyone understands you can charge an EV even with just a regular 15A 120V plug. Stuck at your father in laws out in the country? They've still got a plug.
Generally, people are uncomfortable with high pressure explosive gases. I think overall, hydrogen gas a better shot in industrial/heavy trucking markets than consumer transport.
No it isn’t. In fact, the opposite is true. It’s much harder to wire up millions of charging stations with the necessary amount of power, than to deal with high pressure gas. We’ve just normalized the danger of high-voltage electricity. In reality, this is just as safe if not more so, and a lot easier to pull off.
Erm, no buddy. Everyone's entitled to their incorrect opinion, and this one's a doozy.
How much big of a tank of H2 do you need to effectively equal the energy capacity of a lithium ion pack? If the tank needs to be reasonably sized, how high is the pressure? How do you ensure hydrogen embrittlement isn't a problem on both the tanks and the transport pipes/storage tanks? How does pressure correlate with exfiltration?
Flying wires is a walk in the park, especially competitively.
A 700 bar tank will store more than energy than a similarly sized li-ion battery.
As an energy storage system for cars, the problem is already solved. People are just repeating the same anti-progress rhetoric that was used against battery cars.
700 bar?? 10000 pounds/in^2??
No, you've unfortunately lost your grip.
We've been doing it for over a decade now. It is shown to be safe.
No thanks. I'd much prefer electrified mass transit. I'm saying this as a former manufacturing engineer, there's quite a bit that can go wrong with cyclically pressurized vessels in subtle ways that are difficult to non-destructively evaluate.
This is not the path forward for anyone but heavy industry.
Then you are just being old and outdated. It is totally safe.
