“…Likewise, the results reveal that from the year 2035, proposing complementary actions to significantly reduce NO x and CO emissions is important, principally, in HDFV. In other words, for this class of vehicles, a quicker transition to zero-emissions than for the HDPV is necessary, where new technologies like hybrid, electrical, or fuel cell trucks, not only could reduce emissions, but also provide economic benefits and fuel savings [41][42][43][44].…”

In this study, the use of compressed and liquefied natural gas is evaluated for heavy-duty passengers (HDPV) and freight vehicles (HDFV). The evaluation is conducted considering the socioeconomic and vehicle fleet characteristics of Colombia. The energy consumption, the CO2, and the pollutant emissions of a baseline and four natural gas penetration scenarios are analyzed. The results show that the inclusion of natural gas reduces the energy consumption per capita of the HDPV and HDFV by up to 40% by 2050. Furthermore, PM2.5 emissions per capita are reduced up to 77% for HDPV and 90% for HDFV, while CO emissions per capita decreased by 82%. Additionally, the technological renovation of HDFV emerges as an effective way to reduce pollutant emissions in the medium term. The establishment of strategies to make HDFV cleaner and more efficient is imperative for the long term. Finally, a sensitivity analysis is conducted to evaluate the influence of the gross domestic product per capita (GDPc) over the indicators analyzed. The results show that higher GDPc demands more ambitious actions to decarbonize the transportation sector, since a considerable increase in energy consumption and emissions from heavy-duty vehicles is identified.

“…Here, the prototype of the PHET is a heavy-duty truck, which has great prospects in the market for multipurpose transportation. [24,25] The configuration of the PHET is given in Figure 1, where a parallel topology has been chosen. It is composed of an engine that is connected by an auto clutch to an electric motor, an automated mechanical transmission (AMT), a power battery, and the main parameters of the powertrain components are given in Table 1.…”

The parameter optimization coupled with the control strategy and target driving cycle directly affects the performance of vehicles. This paper proposes an optimization approach for a plug‐in hybrid electric truck (PHET), which considers comprehensive performances including fuel economy, emissions, vehicle drivability, safety, and dynamics. First, 10 initial design parameters are selected from powertrain components and a real‐time energy management strategy (EMS). Then, a definitive screening design (DSD) is proposed to simplify the design parameters. Finally, non‐dominated sorting genetic algorithm‐III (NSGA‐III) is proposed to solve a constrained many‐objective optimization problem with 9 objectives, and the design space is refined through a sensitivity analysis. Simulation results demonstrate that the proposed optimization approach can achieve significant improvements regarding both the comprehensive performances, power repartition, and system efficiency. The simulation is conducted both on Chinese Heavy‐Duty Commercial Vehicle Test Cycle (CHTC) and Urban Dynamometer Driving Schedule for Heavy‐Duty Vehicles (UDDSHDV). In addition, to guide a decision maker (DM) to make trade‐offs among many objectives, preferences are also incorporated into the solutions.

“…In Australia, the Department of Infrastructure, Transport, Regional Development and Communications (DITRDC 2020) estimated that 620 deaths were related to air pollution in 2015 alone, costing the economy approximately $9.2 billion. Reducing CO2, NOx, PM and other air pollutants is the main challenge for policymaking and strategies to transfer diesel truck fleets from low to zero emissions (Giuliano et al 2021).…”

“…Other researchers echo these views. In recent research using a simulation approach with California as the base, Giuliano et al (2021) found that natural gas hybrid trucks are the most cost-effective emission reduction choice. After 2025, BETs will be a good option for emission reduction.…”
