There’s already a trial of CO2 capture at a trash burning facility in Oslo. I could see trash burning + CO2 capture becoming viable over time. Especially if that CO2 capture is paid for by carbon credits. (Yeah, reuse and recycle first, but eventually everything degrades and burning is in the end the best option , especially as modern processes lets us filter out heavy metals and toxic chemicals circulating in our materials)
I could also see e-fuels become competitive for larger remote islands that would otherwise import fuels. Could make them self sustaining. If they don’t go all-electric that is.
The jet fuels will be largely offset by battery electric flights IMO. Most miles flown are short range. It’s still a couple of decades out but I’m certain battery electric will be viable for short range flight eventually. The main challenge is designing the plane from the ground up to get the efficiency advantages of electric flight.
So I really don’t think we’ll end up needing all that much CO2. It’s basically fuel for a subset of planes and ships, and feedstock for some chemicals. That’s a minor part of the oil/gas usage and CO2 emissions today.

Many organizations in Ithaca believe that the airport is a competitive disadvantage. Airlines are refusing to adopt next generation small aircraft like https://en.wikipedia.org/wiki/Embraer_E-Jet_E2_family https://en.wikipedia.org/wiki/Embraer_E-Jet_E2_family even though the lower operating costs and better comfort (e.g. people who are riding an E2-Jet to get on a 737 would be shocked that the regional jet is a lot more comfortable than mainstream narrowbody airliners.) Since regional jets are going extinct there will be a market for something else, maybe electric aircraft, because the competition from legacy aircraft isn't there.
