it will work by capturing CO2 ... from the air. In a separate process, electrolysis splits water into hydrogen and oxygen. The hydrogen is mixed with the captured CO2 to form syngas, which can be transformed into jet fuel = really expensive. While companies are experimenting with high tech ways to capture CO2 from the air, there's already a very simple, efficient way to do it - growing plants. And aircraft are already flying on renewable fuels made from plant biomass. "alternative fuels will become competitive, if the environmental costs are built into the cost of flying, but that will mean more expensive tickets. It'll highly depend on social pressure but there are no technical objections."
