If you are seeing stuff that suggests ammonia will get very close to parity with oil, that's really fascinating, I hope it pans out that way. The IAE is more optimistic than I am about ammonia transport, while still listing some significant hurdles:

I think it's a good report, and you could read it to be more convinced of either of our positions.
Sorry we're talking past each other. You did actually change my mind a bit, if it's any consolation. Agree it's too hasty to say electrons are always better than atoms, though I'm still optimistic about more supergrids. My main remaining concern is just that, as you change your power mix away from oil to generate more ammonia, or electrolytic hydrogen, or whatever, the case for shipping fuel erodes significantly, because you can just move generation closer instead.
Sorry we couldn't get to ground on this one. Thanks for your points all the same.
