Toyota wants hydrogen to succeed so bad it’s paying people to buy the Mirai::Toyota is offering some amazing deals for its hydrogen fuel cell-powered Mirai. That is, if customers can find the hydrogen to power it.

In the near term, it’s pretty clear that zero-emission, light-duty vehicles will need to rely on batteries. So why are Toyota and Honda (and Hyundai and others) still so bullish on hydrogen?

To some degree, it’s like they wanted to invest in an image of being climate-conscious and technologically innovative while eschewing electric vehicles — the most common vision of a low-emissions transportation future.

Why is this article so agressively angled?

While it's clear the infrastructure isn't there right now, isn't hydrogen in the long term a clearly better alternative than ev's? The biggest problem with EV's being the battery, with all the horrible chemicals that go in to making them.

Shouldn't hydrogen, in the long term, be the obviously greener alternative, or am I missing something?

Hydrogen cannot be greener than an EV, because it's just an EV with more steps. It's energy intensive to turn electricity + water to hydrogen, transport it, pump it, then convert it back to electricity.

The losses from simply running electrons through a wire are very small.

It is physically impossible for hydrogen cars to ever be as green as EVs. In order to do so you'd have to break laws of physics.

E: ok people. You live in your little fantasy world where thermodynamics aren't a thing.

In a pure fuel comparison sure, does that still hold true when you also factor in manufacturing?

You conveniently forgot about battery charging and discharging losses.

Yes.

I didn't. Those are very small. Compared to the losses of a HFCEV or even worse, a combustion hydrogen car.
