You are clearly misrepresenting my point. Your authority is not really an authority for a bunch of reasons. One of which is how he is basically a retired petroleum engineer with very little understanding of the modern state of hydrogen. And yes, this usually implies an old person, something Arthur C. Clarke noticed in one of his writings about elderly scientists. And while your link is from this year, he's been saying the same thing for many years now without change. In fact, the only recent change in tone is his exacerbation, as billions of dollars are being invested anyways and he is upset about that.

You are not picking a critical engineer at random. You picking basically one of the very few credible critics, and they're all basically known to the community. The rest of the engineering community in this sector are certainly not as skeptical. In fact, you completely ignored my link about engineers that are doing real work in this area.

I asked previous about "who's actually saying this?" to the question of engineers that doubt hydrogen. And that question is still relevant, because outside of a tiny minority of scientists and engineers, most of whom are outdated and poorly informed, the rest are just armchair experts and random celebrities.

So the point is that you are simply wrong about your understanding of the issue. The intellectual community fully accepts the possibility of hydrogen as a widespread fuel and a way to solve climate change.
