Tesla owners are overwhelmingly men, and the most common occupations are engineer, software engineer, and manager of operations, one study found.
Except those fundamentally limits are far higher. The fact is that hydrogen stores energy at 120 MJ/kg. Even at 5% weight efficiency, that’s 6 MJ/kg. Or 1,666 Wh/kg. Far beyond any battery.
Your link is seriously lying. 8x is the gap between lead-acid and li-ion batteries. The claims are simply impossible. The author must be unknowingly comparing lead-acid battery powered cars to li-ion battery powered cars. I cannot see any other way his claim is true.
A lithium-air battery is literally a fuel cell. In fact, what did you think hydrogen fuel cells were this entire time?
On one had we’ve got links to the department of energy and to Wikipedia. And just some hand waving on the other hand.
It’s wrong because li-ion batteries at the time were way better than what it claims:

This is from 2009, and already we reached 675 Wh/L. So there’s no way the DoE link is true.
Driving with something that power dense is incredibly dangerous. You’re literally driving a bomb, dynamite is 4.6 MJ/kg
