Brief 🧵 (hopefully) reflecting on this blue hydrogen thing.
Basically, the paper’s calculations potentially represent a case where blue H₂ is done really badly & without any sensible regulations.
And then cherry-picked a climate metric to make it look as bad as possible.
I'm not tweeting the whole "Blue hydrogen worse than natural gas" thing because, well, it's Mark Jacobson. If you make implausible assumptions, you get implausible results. Even if those results fit your desired narrative, honest folks are duty bound to either dig in or stay out.
