On-Board Post-Combustion CO2 Capture in Light-Duty and Heavy-Duty transport 2020-37-0012

The European Union set the CO2 emission limit in the transport sector that will decrease in the next years. The purpose of this work is to assess through technical analysis, a system that captures part of the CO2 from the exhaust gases of duty vehicles. Two distinct categories of vehicles are considered, those with a mass lower than 3.5 tons and those with a higher mass. For the light-duty category, the analysis is developed estimating the consumptions and emissions based on the WLTP homologation cycle by means of the software Excel. For the heavy-duty category, the consumptions and the emissions are determined by means of the software specifically developed by the European Union for heavy-duty vehicles named VECTO (Vehicle Energy Consumption calculation Tool). From a literature review, different technologies are considered. The most suitable technology is selected. A possible way is based on the adsorption through the metal-organic framework (MOF). A dedicated review to select the most promising material indicates which can assure the best performance. The performances are evaluated based on the features of the material. Two strategies can be considered to manage the CO2 captured. It can be regenerated or can be stored in the vehicle until the vehicle reaches the refueling station. Both strategies are evaluated, and the systems for the on-board capture with the selected material is design and estimated in weight and volume. The coupling of the capture system with the vehicle allows the estimation of the performance in the WLTP cycle for the light-duty vehicles and through the software VECTO for the heavy-duty vehicles. The CO2 captured regeneration and the
