The one thing H has going is quicker fills at the pump, right? Being low on joules is a pain when you're going to work in the morning, but it's a royal pain if you have to wait a half hour to charge.

Yep if you have a hydrogen pump nearby it will probably fill faster than a charger. Not sure if they need attendants like a propane fill. If you have a plug at home though thats much more convient at least to me when going to work.

  You do not need an attendant the hydrogen stations I’ve been to.

At least you get a half hour to think about how you should have plugged it in last night.

  For me that'd be half an hour to ruminate on how my apartment has no place to charge a car. I am not getting an EV anytime soon unfortunately.

    The general lack of EVs in multifamily housing is concerning for EV adoption - the only places where it's really possible is if the community offers a garage and the site's willing to book an electrician to install the 240v outlet.

      I am fortunate that my building committee is pretty forward looking. It helps that many owners actually live there. But it is a significant project and it doesn't look like EV charging standards (plugs, power delivery) are set across all manufacturers. The balance of effort+money vs benefit/risk means we will keep driving what we know for now. I know the tide will turn sometime, but not anytime soon.

30 mins at a supercharger is hundreds of miles of range...that's quite the commute. But if you're at home - yes, I guess not having any charge is an inconvenience in the morning, but so is not having any gas or hydrogen. Neither should happen if you are even remotely responsible and on top of your life.

On the other hand, if we ever build out electrified road infrastructure, one might be able to recharge a battery electric vehicle without even stopping just by pulling power from rails embedded in the road or overhead power lines.

Even there it's not a clear-cut victory. The last time I looked at it, it turned out that hydrogen filling stations need a significant time after fueling each car to get back to transfer pressure. If you want to fill your tank right after someone else, you'll have to wait for a bit. But overall, filling time is not that big of a deal. Most people don't really drive that much, and the car spends the majority of its time in a parking lot. In practice it turns out that just charging it at home every day is more than enough to keep a battery full. In addition to that, commercial vehicles often have a driving time limit. As long as the recharge period is shorter than the mandatory break, you are not going to care about the recharge speed. And both battery capacity and charging speed are quickly improving. There might be a small niche for hydrogen, but it's disappearing rapidly.

Unless your work is 300km away, that’s not true. Two minutes = 50km at a supercharger, and for that use you can slow charge at home.
