New Concept (IMAGE) Ecole Polytechnique Fédérale de Lausanne Caption 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.
