Damning new report finds nearly all major car companies are actively sabotaging world’s efforts to avoid catastrophic global warming, and Japan companies are the worst.
Right. At the moment, hydrogen production is too costly, energy wise. If we could find an easier, better way to make it, that would change the game entirely.
Carbon is what matters, but not in the way the hydrogen-pushers want you to think:
It doesn’t matter if the fuel has carbon in it, if the carbon is part of the short-term carbon cycle. Biodiesel, for example, releases no net greenhouse gases even though it has lots of carbon in it.
The dirty secret of hydrogen is that the vast majority of it is made by cracking fossil methane. (My previous comment about combining hydrogen with carbon to make synthetic liquid fuel charitably presupposed it was made the right way, by electrolyzing water with solar power, but most hydrogen production is not like that)
In other words, anybody telling you that hydrogen is better for preventing climate change than biofuels – despite them containing carbon – is trying to hoodwink you.
Ok. Because over here we’ve had a hydrogen station that’s been producing hydrogen at the station itself via electrolysis using electricity from the grid. It’s been working fine so far.
I’m gonna have to look into your claim about cracking methane being the way the majority of the hydrogen is created.

The entire premise of hydrogen is dumb.
We would legitimately be better off combining it with CO2 to make synthetic gasoline and just use it with normal vehicles and infrastructure.
Dude, that produces methane, I think?. The whole point is to avoid combustion engines to prevent greenhouse gasses.
The way hydrogen is being used is to work with hydrogen fuel cells which is electric.

From https://solaredition.com/green-hydrogen-production-paths/ :
Only “green hydrogen” (4%) is actually good. For the other 96%, it would be better to just use the source hydrocarbon as fuel directly.
In other words, for the most part, the entities pushing hydrogen are mostly engaging in greenwashing bullshit.
