I think battery swaps have been a failure so far, it’s not a new idea.

High efficiency hydrogen fuel cells are probably the right course for now, if we could only find a safe efficient way of storing hydrogen…oh! I know! Renewable hydrocarbons! Why didn’t anyone think of that?! 🙄
Another problem is the frosting that happens while refilling in cold locations. I'm bullish on it's future though if that can be solved.
The problem I see is energy density. Sure there is pressure, but who wants to drive a bomb around. No matter how safe they say it is, 10000 psi is 10000 psi, and released too quickly your molecules are going to be scattered to the wind. Crashes are chaotic. I’ve seen kinetic energy do some crazy stuff.
They have performed tests firing a 50 cal bullet into the fuel cells. They're practically built like an aeroplanes black box. You'll be disintegrated by the crash before they get damaged.
I’ll see if I can find some tests. Interesting. It’s still relatively low energy density compared to diesel though. Electric makes great sense for metropolitan transport, for freight and distances though renewable diesel is the ticket IMO.

Yeah this relies on swappable batteries being installed in the car in the first place so that the switch takes ~10 mins. Tesla's don't have quick swappable batteries.
