This also isn't taking into account battery advances like solid state. Amptricity is preselling home batteries now.

Batteries can't chemically be as energy dense as hydrogen or fossil fuels. They will improve, but not significantly.

Yeah. They look to be about 2x-3x as expensive as just an LI battery, but there are insurance savings to take into account and the fact that they are significantly safer and more efficient and should last about 10-20y longer. I think the cost is worth it, but they're also the first people on the scene. I expect competition to make them close to LI cost.

I try not to get too hyped for things just because there are a few pre sales. Once production begins in Ernest and there are a few thousand happy customers I think I'd be ready to make the move, until then it's something for people with money to burn and gamble.

I'm not spending my money on it, but I'd say that based on preproduction and existing samples and manufacturing that is online already--solid state is further along than HCV mainly because there is so few HCV infrastructure.
