> Which one? I’m guessing you just did research on this and just learned they existed? One of them costs $80/liter now, but said they can get it down to $6/liter through scaling.
You do realize there's only a 20% difference between $6/l and $25/g? IOW, they're basically the same price.
> Why? propane is shipped in, you don’t believe getting compressed gas in an emergency is possible?
Propane is shipped as a liquid with a high volumetric energy density. Hydrogen is shipped as a gas with a very low volumetric energy density. You'd need a lot of tanks of hydrogen to replace a single tank of propane.
Hydrogen needs to be regularly recompressed, requiring a lot of electricity. It's then further compressed before fueling a car, meaning that the hydrogen fuelling stations in California can only fuel 3 cars per hour.
Hydrogen leaks like crazy. NASA delayed the Artemis I mission by 3 months due to hydrogen leaks. If NASA can't do it...
> Every time you charge it, you lose a little range. This isn’t true with a liquid fueled vehicle in that the fuel tank gets a little smaller after every refuel.
The fuel efficiency of a gas car gets worse over time, so the same effect happens to them too.
