It has nothing to do with Elon. He just said what intelligent people who have looked into the physics of the problem have known for a long time.
Hydrogen ONLY makes sense for things like trains. Do you really think it is better to use electricity plus extract then process oil to create hydrogen, burn oil to tanker truck that hydrogen to a gas station, use electricity to store the hydrogen, then waste electricity converting it to its components through a rare earth catalyst plate to charge a battery… versus transmitting electrons over a wire to charge a battery? Hell, even the fact that EVs can charge at home instead of constantly driving extra miles to get to a gas station to refill their hydrogen makes them better for the environment.
Yeah, mining rare earths for batteries is bad. But you are an idiot if you think the same thing isn’t happening in the creation of hydrogen and the rare earths used in hydrogen motors, along with the inefficiencies of transport and storage of hydrogen.
Not surprising. Korea has a HUGE population of smokers. While it has gone down in very recent years, back in 2017 almost half of all male adults were smokers. They still have 30% of the adult male population as smokers, though, which is double the US male smoking population.
