Yes. That's remarkable more sensible than futzing with naked hydrogen molecules, though the challenges here have been great as well.

I covered the topic in a series of posts based on then-new research about six years ago. That's ... not developed much further:

The main development since has been Foghorn, a Google (Alphabet) project attempting to develop the technology. It failed.

What is the oil-cost-equivalent of existing synfuel technology?

(for uses such as air travel)

IIRC at $150 oil these synfuels were already competitive?

Varies by study, though upshot of the USNRL study wss that for net cost point-of-use (deployed carrier task force) it is competitive now (roughly $50-60/bbl cost of oil).

I'd argue that fossil fuel oil is grossly underpriced, by an order of about 10^6, but that's a longer discussion.
