Hydrogen is a politically driven scam. It is currently made from fossil fuel, with a byproduct of CO2. Far more CO2 is produced in this process than if the car fueled by hydrogen simply ran on gasoline. The electrolysis method of producing hydrogen requires far more energy than what is usable in the hydrogen. The day that the lofty hydrogen dream finally dies is the day you will hear cheering from most of us in this forum.GO HYDRO!
Exactly. They take natural gas, which is mostly CH4 (methane), and strip the `H4s` (hydrogen) off to use as fuel. Now the C (carbon) is lonely and naturally clings to the nearest O2 (oxygen) floating around, so now we have a bunch of CO2. Not only does it produce carbon dioxide, but it consumes valuable oxygen.most hydrogen is made by "stripping" LNG so that the carbon ends up as co2, and some of the hydrogen can be collected. again
You are right, they don't defend Hydrogen at all. They explain how the automakers convinced the government that Hydrogen is better, how they dangled the hydrogen dream in front of us and continue to do so, even though the necessary technology is still 30 years away. Just before CARB voted to cancel the EV mandate, its head, Alan Lloyd, got a job in hydrogen research. The hydrogen folks promise long ranges and renewable fuel, even though they still have less range than the EV1 did, and use fuel that is more damaging than the gasoline that I/we are addicted to. THIS is why I hate the movie - because it reminds me of all this stuff and makes me angry!I thought they explain near the end of the film that hydrogen is a bit of a red herring. They do explain that it diverted attention away from BEVs, but I don't remember them defending it.
As one who has fiddled with hydrogen on many vehicles, my homemeade electrolysers worked well, but for the average joe are too much to maintain. 10% -20% is easily achieved but as it is concurrent with the dinosaur's feedbag we need to look further ahead to electric.and the bit of hydrogen made with electricity... its about 10% efficient, batteries are 50-90% efficient. (lead or lithium) so you can already see how much power you're throwing away, and even after that, theres the rather poor efficiency of a piston engine or fuel cell to burn the hydrogen back into power or electricity.
and with the poster above, most hydrogen is made by "stripping" LNG so that the carbon ends up as co2, and some of the hydrogen can be collected. again, throwing away tons of energy that could have just as well (or actually, better) have fueled a car.
OK, now I understand.You are right, they don't defend Hydrogen at all. They explain how the automakers convinced the government that Hydrogen is better, how they dangled the hydrogen dream in front of us and continue to do so, even though the necessary technology is still 30 years away. Just before CARB voted to cancel the EV mandate, its head, Alan Lloyd, got a job in hydrogen research.

nah, there is no conspiracy related to hydrogen, only one thing keeps it from the market, HORRIBLE WASTEFUL INEFFICIENCY in every aspect, from start to finish.the scum that be you accuse me of aligning myself with are what's keeping the tech off the market
TV shows, just like most other public media, don't bother themselves with paying attention to efficiency and economics of any particular subject they show off. Afterall, most viewers aren't educated enough to grasp at the concept of efficiency, which has been proven million times on every Internet forum where people like you post in support of hydrogen.i must be the ONLY one here who watched alan alda's scientific american frointeirs show on PBS religiously as no one seems to remember seeing the scandinavian hydrogen station that was basically a giant hydrogen fuel cell run in reverse. electricity & water go in, and hydrogen comes out.
That has nothing to do with hydrogen, and if a holier than thou argument is the best you can do, you won't win many supporters here.i'm way greener than you are in that count.
As others have pointed out, you seem to lack understanding of the poor efficiency of the entire hydrogen process, no matter how many times we explain it to you. I guess you need to watch some more TV shows, maybe some with real science in them. Here's a small bit of info you can ponder upon, burning hydrogen in an ICE is probably the very least efficient use of an already inefficient product. Since there is zero hydrogen infrastructure any hydrogen vehicle is extremely hampered by range issues and charge times.....his usual misinformed hydrogen rant....
