Hydrogen Achillies Heel is vaporization during on-board storage. It's not a solvable problem. It is just physics. Hydrogen is great for rockets, personal automobiles not so much.

Not solvable seems pessimistic Would it be feasible if there was a pump that could keep the tank pressurized to offset the lost volume. Or a tank that could change volume as hydrogen depleted. Not saying it's possible, just thinking outside the box.

Tank heater would increase pressure. Had a heater for my nitrous bottle long ago.

Liquid hydrogen is stored at -200 to -260 deg. C at reasonable pressures to remain portable. It boils off because like any cooler, the tank eventually absorbs heat. The box is affordability tied to the realism of safety...

I don't see how we are suddenly going to have hydrogen fuel cell infrastructure. This seems like something that dealerships would have to initially support.
I mean, maybe, but in an ICE or an EV, the fire isn't usually so instantaneous that you can't just get out of the car. An explosion sure is though.

Hydrogen refueling is pretty complicated, and the stations are pretty expensive. It's not just as simple as taking gas stations and making them hydrogen powered. And they'd likely not be self-service because of the safety concerns of compressed highly flammable gases.

Oh and that's all discounting the fact that hydrogen takes about 3x as much energy as filling up a battery. Everyone concerned that our electricity grid can't handle filling up BEV's... just wait till we have to triple that demand to create hydrogen...

Im sticking to basics and so much easier to go with a gas car than an EV, could end up bad with EV charge rage in apartment parking, yep it's M GUY spelling it out again.

It's pretty basic, and repetitious, isn't it? Amazing that there's still people who continue to watch different people say the same thing over and over again... Confirmation bias wins again.

That said, I'd never go EV if I lived in an apartment. But in the house I live, it's incredibly convenient. Pull in and once a week plug in, charge while sleeping. Never have to think about stopping for gas on my drives. For a daily commuter, it's quite the luxury experience.

For my other cars - nah, ev sucks. I'll keep my six speed bimmer for jollies and my mountain/road trip suv as ICE.

^ Even so, it's important to being shown again (thought it looked familiar) so that EV buyers in apartments don't fall into the same trap as Miguel Frolich did. The bottom line here is to never rush into anything particularly when buying an EV before doing the homework..

The same can be said about anything. However we don't have 445 page threads about those.

Anyways to answer the original question again, yes I still want an EV, so much so I just traded in the Model 3 for the new highland Model 3. I gotta say it's better in almost every way. Can't wait to see what the new Y is going to be like.

High probability I will be trading in the Cayenne for another EV in the next few months. Might venture outside of Tesla and try something else or might not.
