A Life Cycle Environmental Impact Comparison between Traditional, Hybrid, and Electric Vehicles in the European Context

Sustainability

Global warming (GW) and urban pollution focused a great interest on hybrid electric vehicles (HEVs) and battery electric vehicles (BEVs) as cleaner alternatives to traditional internal combustion engine vehicles (ICEVs). The environmental impact related to the use of both ICEV and HEV mainly depends on the fossil fuel used by the thermal engines, while, in the case of the BEV, depends on the energy sources employed to produce electricity. Moreover, the production phase of each vehicle may also have a relevant environmental impact, due to the manufacturing processes and the materials employed. Starting from these considerations, the authors carried out a fair comparison of the environmental impact generated by three different vehicles characterized by different propulsion technology, i.e., an ICEV, an HEV, and a BEV, following the life cycle analysis methodology, i.e., taking into account five different environmental impact categories generated during all phases of the entire life of...

Modelling of life cycle cost of conventional and alternative vehicles

Scientific Reports

Over the past decade, the passenger transport segment has undergone significant changes, particularly in the way vehicles are propelled. These changes have been influenced by the global drive to reduce the environmental burden associated with the operation of vehicles. Although these trends are primarily focused on the environmental aspects of vehicle operation, the economic aspects inevitably associated with the operation of each vehicle are also changing. This article deals with the calculation of life cycle costs, or the return on investment for vehicles with alternative drives compared to conventional drives. In order to obtain objective outputs, a mathematical model for the calculation of the life cycle costs of passenger vehicles has been developed and applied to these vehicles. The presented mathematical model expresses the acquisition costs and mainly the ownership costs for operation and maintenance. Finally, a comparison of the whole life cycle costs of selected vehicles w...

Comparison of Different Vehicles Driven by Alternative Fuels and Hybrid Driveline Focusing on Emission, Efficiency and Economy

2016

Air pollution is becoming an important issue in big towns, in particular in city centres, where the density of traffic is high. Both, passenger cars and commercial vehicles are responsible for air quality. In the last decades more and more transportation companies changed their conventional vehicles into any kind of alternative vehicles. The aim of this paper is to investigate the economic and environmental effects of introducing alternative fuels and powertrains in cargo vans. All of the simulated vehicles were equipped with internal combustion engines, but they are operating with different fuels. Gasoline, methane, ethanol and hydrogen fuels are used in these engine models. Conventional and hybrid powertrains are compared too. Only the gasoline fuelled engine is simulated with hybrid driveline besides the conventional ones. Both micro- and full-hybrid vehicles are modelled. Instead of dynamical analysis we focused on efficiency and emission therefore tests drive cycles were simula...
