> 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.
This all sounds a bit energy intensive to me and that it would significantly reduce efficiency.
> The whole process takes place within a capsule measuring 2 m x 0.9 m x 1.2 m, placed above the driver’s cabin. “The weight of the capsule and the tank is only 7% of the vehicle’s payload,” adds Maréchal. “The process itself uses little energy, because all of its stages have been optimized.”
> The researchers’ calculations show that a truck using 1 kg of conventional fuel could produce 3kg of liquid CO2, and that the conversion does not involve any energy penalty.
