Does anyone still believe EVs are here to save the world from climate change?

Their sole purpose is to save the auto industry.

There are pretty clean combustible sources out there or even alternative electrical sources out there, but somehow humanity has gone with big, heavy, rare mineral hungry batteries.

What's the deal against hydrogen? Toyota made a car that made it to market, it can't be that dangerous if it was sold in certain regions with extensive safety testing procedures. I know the problem is getting hydrogen at the pump station but other fully battery dependent cars have had that same issue before.

I'm sure hydrogen has other problems (conversion efficiency?) but what about ethanol? Better than gasoline, no? At least 40% less greenhouse gases out of the tail pipe, and its production is pretty mild for the environment compared to batteries. It wouldn't make cars that much more complicated either, and you could "easily" convert your ICE car. Of course, at the scale we are talking about the gains would be way lower given a 5 year timespan vs batteries

Hell, there are others.

Such a weird set of events dictating the future of cars ngl, some of the alternatives may have had come sooner if someone focused there (I know Brazil has some minimum ethanol requirement that seems like a good idea while transitioning).

		Clean hydrogen begins with electricity and then loses a vast amount of energy in the conversion process. Also it’s extremely pressurized and/or cryogenic, and one of the most difficult molecules to store. If there was a process for converting electricity to ethanol and burning it that was more efficient than batteries, we’d be using it instead of batteries. Other sources like corn-based ethanol have their own problems that have been pretty extensively covered elsewhere. In fact, all of this stuff has been covered elsewhere and great answers are available with a search.

		Batteries don't dump half their capacity overnight because they're filled with the gas that doesn't want to be contained.

		Man you see this crap pop up on here so many times I'm almost starting to wonder whether car industry shills are just trying so sow seeds of doubt with misinformation.. haven't we agreed by now that the only future we should strive for is one that can plausibly be made completely emmissionless...? All options you list either still have emmissions associated with them or are so hilariously inefficient that we would need to blanket half the globe with PV panels to power everything. All alternatives have been extensively explored and the only and most efficient way to power cars in an emmissionless way turned out to be a battery electric drivetrain. There is a reason all the options you list didn't take off.

Surprised to see this dumb of a take on HN. How exactly are they saving the auto industry? And yes they are obviously better for the environment. Are you just being conspiratorial for the sake of it or do you actually think this?
