There are some interesting start-ups betting on just that, that carbon capture to general hydrocarbons in a neutral way will outcompete electrifying certain sectors, e.g. https://caseyhandmer.wordpress.com/2021/11/01/scaling-carbon...

(Yeah, linkedin sucks)

Surely that's much easier and less ressource intensive than using less planes and helicopters.

It doesn't matter how energy intensive it is. If people are willing to pay a premium (they are), there will be a market.

Right now, the market is artificially big, because you don't have to pay for the negative externalities of carbon.

> you don't have to pay for the negative externalities of carbon.

We aren't yet seeing much indication that there will be a global tax/fee on the externalities of carbon. That means even if local policies are implemented for certain cases (eg. no gas cars in the city, no coal power in one state), there will always be somewhere on earth willing to burn dirty coal to make helicopter fuel for export.

So you tax the carbon at the importing country. This is a solved problem.

The WTO most favoured nation rules don't allow that. Which is why nobody does it.
