Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%. The EPFL system captures CO 2 directly in the trucks’ exhaust system and liquefies it in a box on the vehicle’s roof. First, the vehicle’s flue gases in the exhaust pipe are cooled down and the water is separated from the gases.
