If fuel from air can be made efficient, then combined with highly economical fusion, I could see it being viable. I'm not sure it will ever be cost competitive with long tail oil and gas, though. And that's at least 30 years out.

If we had some ham, we could make ham and eggs, if we had some eggs.
"Highly economical fusion" is probably an oxymoron.
There are multiple companies closing in on highly economical fusion. Enough so that they're receiving hundreds of millions of dollars of investment from very savy private investors. My money is on Helion getting there first.
Are you aware that tritium like hydrogen is very hard to contain as it's as small as hydrogen and very nasty as it's highly radioactive. That alone prevents this technology to become cheap any time soon (assuming they get Q>1).
