> $25/gallon once it hits mass production. 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. > Hydrogen is completely non-viable for emergency situations. Why? propane is shipped in, you don’t believe getting compressed gas in an emergency is possible? Again, do you have a financial interest in EVs? Or you just trying to win this argument? I’ve never met someone so in love with electric cars. I can certainly understand the desire to get rid of gasoline, but to force people into electric when there’s tons of problems that people see means you won’t get the adoption you’re looking for. You know there’s even another issue with EV I haven’t brought up yet. 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.

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.

  Well you haven’t answered my question about your potential financial involvement with EVs nor why you’re so enamored by them. I’ll continue this conversation and disprove your recent post when you explain why it must be EVs we use instead of any other much better option.
