Capturing CO2 from trucks and reducing their emissions by 90%

Capturing CO2 from trucks and reducing their emissions by 90%

Researchers at EPFL have patented a new concept that could cut trucks’ CO2 emissions by almost 90%. It involves capturing CO2 within the exhaust system, converting it into a liquid and storing it on the vehicle. The liquid CO2 would then be delivered to a service station and where it will be turned back into fuel using renewable energy. In Europe, transport is responsible for nearly 30% of the total CO2 emissions, of which 72% comes from road transportation*. While the use of electric vehicles for personal transportation could help lower that number, reducing emissions from commercial transport – such as trucks or buses – is a much greater challenge.

Researchers at EPFL have now come up with a novel solution: capturing CO2 directly in the trucks’ exhaust system and liquefying it in a box on the vehicle’s roof. The liquid CO2 is then delivered to a service station, where it is turned into conventional fuel using renewable energy. The project is being coordinated by the Industrial Process and Energy Systems Engineering group, led by François Maréchal, at EPFL’s School of Engineering. The patented concept is the subject of a paper published in Frontiers in Energy Research. More Information.
