Interesting technology which claims to produce low carbon fuels by blowing air through towers that contain a solution of potassium hydroxide, which reacts with CO2 to form potassium carbonate. The result, after further processing, is a calcium carbonate pellet that can be heated to release the CO2. That CO2 could then be pressurized, put into a pipeline and disposed of underground, to use the gas to make synthetic, low-carbon fuels
