As long as thermodynamics allow, everything is possible.

The question always is who is gonna pay for it?

Societies have other priorities much higher on their list compared to energy cleanness.

"Natural" Oil is literally finite, we're currently burning everything which died over millions of years, when we say it isn't "renewable" that's not some vague idea about the planet not overheating (though to be sure if we heat the planet up and make it uninhabitable that would suck for us) but that literally it's running out.

So "who is gonna pay for it" is everybody, eventually.

We can literally build complex hydrocarbons from thin air. The problem is again cost (energy).
