Beijing Heavy-Duty Diesel Vehicle Electrification Transformation and Emission Estimation in 2022

Abstract

Road transport is a scenario for the use of fossil fuels to a large extent, and the process of electrification can slow down the use of fossil fuels. This study analyzes the annual emissions of nitrogen oxides (NOX) and carbon dioxide (CO2) of heavy-duty diesel vehicles (HDDVs) and the feasibility of electrification in Beijing based on on-board diagnostics (OBD) of remote monitoring data from more than 9000 HDDVs. The annual NOX and CO2 emissions of 13 industry types were 44,980.9 and 6,658,722.6 tons in 2022. The highest contributor to NOX and CO2 emissions is concrete trucks, accounting for 27.1% and 17.0% of the 13 industry type vehicles. The electrification of concrete trucks can greatly reduce diesel emissions in Pinggu and other districts and realize regional emission reduction management. The CO2 emission factor of passenger buses in Pinggu district is significantly higher than that of other districts, which is 1212.4g/km, and the electrification of passenger buses can significantly reduce CO2 emissions in Pinggu district. This study investigates HDDVs in Beijing, provides a scientific basis for the electrification management of key models in Beijing, and provides a regional reference for the electrification trend of HDDVs in various countries worldwide.
