Hydrogen will not be a threat to any electric personal vehicle simply because it’s 3x less efficient (electrolyze water to split it) and thus 3x more expensive to run.
God/Allah/Nature obviously don't understand disruption, growth mindset and can-do-spirit. facepalm
There are hard physical limitations that no amount of human ingenuity can do anything about. 237kJ/mole is the theoretical minimum of energy required for water electrolysis. energy->electrolysis->energy round-trip efficiency won't exceed 45%, even if everything, from the energy source to the car wheel spinning, is perfectly frictionless and operating at peak theoretical efficiency. No, you cannot use existing gas pipelines for transporting hydrogen.
For passenger cars, EVs today are already better than what physics allow hydrogen cars to ever be.
> No, you cannot use existing gas pipelines for transporting hydrogen.
You absolutely can. In fact gas companies are already planning this exact thing.
> For passenger cars, EVs today are already better than what physics allow hydrogen cars to ever be.
Your "physics" is entirely pseudoscience.
[note] for pure hydrogen eventually everything except the pipelines will have to be replaced
It's important to remember that hydrogen fuel cells are batteries too. There is no reason for the metal lithium to have magic properties over other battery technologies.
