I've posted on this in connection to molten-salt reactors. You might get fuel from a process derived from captured carbon dioxide, but it will cost $25 a gallon. In other words, not economical, except in war zones.
Unless this process brings that price down, it won't make economic sense.

The obvious question is what do you do with the gas? Any gas can escape, so "sequestration" isn't of much value.
According to the article, it requires 1 gigajoule of electricity to capture 1 ton of the gas. But the processing isn't finished with the mere capture. You have to do something with it. From there, it might be processed back into fuels, but at a cost. If it takes 1 gigajoule, that's about 278 kilowatt-hours per ton.
1 gigajoule power per ton captured: MIT engineers made a cheaper and more efficient device to trap carbon dioxide https://t.co/fqr7jE1DX5 via @thenextweb— Greg Meadows (@BootsandOilBlog) December 2, 2019
