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.

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...

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... |

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..

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. |

I've been driving BMWs and ///M cars for 30+ years and EVs for 10+ years. EV charging infrastructure is extremely well developed along both coasts. Especially the Tesla (L3) SuperChargers. Over 7+ years of Tesla ownership, I've yet to EVER wait in line for an EV charger, and I've taken Teslas on multiple 500+ mile trips requiring on-the-road charging stops. The only exception that I can site is my workplace, now that EV adoption has exceeded the supply of the installed L2 EV chargers (~20 of them) about a year or two ago. Quote:

They just cite hydrogen (economically and environmentally non-viable) as an excuse to downplay EV appeal and adoption. The same folks are happy to argue that "EVs are not ready", and we should wait for "solid-state batteries" before EVs should be seriously considered. Quote:
As a 2nd or 3rd car - EVs are great. As a daily driver/commuter car - EVs are absolutely PERFECT for financial and tech assistance/ADAS reasons. Quote:
I know many non-car friends who think it's the latter. Having said all that, I do prefer driving the ///M3. Every time. On track and to work. My wife and kids prefer the EVs. YMMV, a

Yeah, you can just keep a bunch of liquid nitrogen around to cool it down. I'm sure that doesn't use any energy.

tesla shares have spiked because he's literally going to be "first dude" (where's melania?). So anything related to ev will be massaged for max benefit to tesla/musk.

I would turn that around a mite and put the enthusiasts first who may think that non-car people are lost souls, ships that just pass in the night . But...glad you prefer your gas M3 |
