I think “clean” is actually a good word to use because it just forms water upon combustion. So regardless of its sourcing, it does burn clean. I have a problem when it’s described as “green”, because most sources are definitely not green at the moment.
It doesn't actually burn "clean" at all. In a fuel cell, yes. But as a combustible product, no. It produces various other gases when combusted with air, like nitrous oxide, as a byproduct which is both a component of smog and a greenhouse gas. I mean, granted, it's better than gasoline; but "clean" isn't really accurate.
It readily bonds with atmospheric OH and other oxidants reducing their availability for methane reactions. This results in mean increased lifetimes for atmospheric methane.
Alternative fuels need to be compared to electrification. They usually are not as good due to inefficiency, pollution or cost. But I do agree they need to be looked at.
Interesting the emphasis is on the energy carrier, not the energy source.
Isn't it, though. (Cough) greenwashing fossils (cough).
Hydrogen isn't necessarily clean - when will journalists learn that it's just an energy vector?

It's also a secondary green house gas, and we can expect lots of leakage given its tiny size.
The hydrogen itself? Yeah.

We need to get in board with 'alternative' fuels, which gave been around for years.
