Re:After many false starts, hydrogen power might now bear fruit

Hydrogen makes sense in industrial applications (steel, chemistry, e.g. ammonia production). Electricity often isn’t even an option there (same with aviation).
I think people tend to be too blinded in their focus on cars here? I don’t think hydrogen cars make much sense. Batteries all the way – but that doesn’t mean that hydrogen is without merit for other applications.
And if you want to replace all greenhouse gases in industrial applications with green hydrogen you still need a shitton of hydrogen (since, yeah, it’s inefficient – but if it’s the most efficient greenhouse-neutral way to get there – what choice is there?), so that’s not something you can just improvise. You need to tackle it head-on.
That’s why I fear people being stubbornly focused on cars. Even if not a single car will ever use hydrogen ever we could still need a lot of green hydrogen for other purposes if we want to be greenhouse-neutra.
