EPFL researchers propose concept to capture trucks’ CO2 and covert it to liquid fuel while driving

In Switzerland, 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.

Scientists propose to combine several technologies developed at EPFL to capture CO2 and convert it from a gas to a liquid in a process that recovers most of energy available onboard, such as heat from the engine. In their study, the scientists used the example of a delivery truck.
