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 EU's 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.
