It's a guarantee that hydrogen production will take off, and in the long-run disrupt basically everything else. All of the critics are trapped in the mentality that green hydrogen will always be expensive. They are totally oblivious to the possibility that it could be practically free.

But it will be practically free, or at least close to it. And that's the problem for all possible competition. How do you compete with something that is either free or close to it? You can't. So in long-run, anything that can be directly displaced by hydrogen will be driven out of the market.
