EPFL team develops on-board system to capture CO2 from trucks; reducing emissions by 90%

Green Car Congress

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. Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%.

New composite reduces rare earth element usage in three-way catalytic converters

Green Car Congress

The high-performance, three-way catalytic (TWC) converter is one of the workhorses of emissions reduction for gasoline engines. The TWC reduces NO x to nitrogen and oxygen; oxidizes CO to CO 2 , and oxidizes unburnt hydrocarbons to carbon CO 2 and water. Adapted with permission from Machida et al.
