Or it stays BUT it can only turn 100t CO2 -> 1l fuel in 7 days. But it is used as PR - "We use 100%* sustainable jet fuel" *up to 100% if it was cheap and blah blah.
And then flight prices soar up 2x boom.
Or they figure out it's cheaper to burn something to produce CO2 than recycle it from the atmosphere.
To start, the company procures “waste” CO2 from industrial facilities. Twelve has developed its own electrochemical reactor to split carbon dioxide molecules into carbon monoxide using electricity. Engineers then use a separate electrolyzer to split water molecules into hydrogen and oxygen. The resulting mixture of carbon monoxide and hydrogen is known as “syngas.”
Finally, the team deploys a multistep reaction called the Fischer-Tropsch process to convert the gas into a liquid — one that’s chemically identical to jet fuel made from petroleum.
I read somewhere that this is worse than just collecting carbon, since jet fuel will be burnt in the upper atmosphere, where it's even harder to retrieve the CO2.
