Simulation of the impacts on carbon dioxide emissions from replacement of a conventional Brazilian taxi fleet by electric vehicles

Abstract

This work evaluates the effects of the replacement of engine-powered vehicles by electric vehicles on carbon dioxide (CO 2) emissions and energy consumption. A case study of a taxi fleet replacement was conducted with the aid of the AVL Cruise software. The simulation was performed under different scenarios of total or partial fleet replacement along a period of 15 years. The scenarios were designed considering favorable and unfavorable conditions for electricity production from a clean source, thus influencing the CO 2 emission factor adopted. The simulations showed that the electric energy consumption by the electric vehicles is about four times lower than fuel energy consumption by the conventional vehicles undergoing a standard test schedule. At the end of the period considered the electric vehicles will produce lower CO 2 emissions than the conventional vehicle fleet by a factor of 10, even considering the most unfavorable scenario of electric power generation. An economic analysis shows that the present value of electric vehicles over the years is lower than that of conventional vehicles, except for the first year after vehicle acquisition.

Analysis of CO2 emissions and techno-economic feasibility of an electric commercial vehicle

“…Under the conditions established in the baseline condition, Fig. 6 shows that the EV is not economically feasibility without considering the revenue from commercial utilization [38]. The NPV is always lower than zero, decreasing every year and closes with the negative value of EUR -212,634.10.…”

Electric Vehicle Deployment and Carbon Emissions in Saudi Arabia: A Power System Perspective

“…to compare the impacts on carbon emissions of deploying EVs within Europe, but also coupled it with a Monte Carlo simulation to model the probability of different outcomes (Casals et al 2016). Teixeira and Sodré assessed the carbon emissions impact of replacing a conventional fleet of taxis with EVs in Brazil using the average method, but also used several averages to account for alternative energy mixes (Teixeira and Sodré 2016). Analyzing emissions from a global perspective using average emissions has also been done (Woo, Choi, and Ahn 2017).…”

Sustainable Road Transport: Alternative Fuels, Electrical Vehicles and Environmental Effects

“…(2016), içten yanmalı motorlu araçların yerine elektrikli araçların kullanılmasında, elektrik üretim sektörünün enerji yapısını değiştirmemesi durumunda ulusal toplam CO2 emisyonlarının değişmeyeceğini kanıtlamaktadır (Hofmann, Guan, Chalvatzis, & Huo, 2016). Ancak, Teixeira ve arkadaşlarının yapmış olduğu çalışmada ise, içten yanmalı motorlu araçların elektrikli araçlarla değiştirilmesinin CO 2 emisyonları ve enerji tüketimi üzerindeki etkileri araştırılmış, elektrikli araçların içten yanmalı motorlu araç filosuna göre daha az CO2 emisyonu üreteceği belirtilmiştir (Teixeira & Sodré, 2016). Mevcut çalışmalardaki farklı sonuçlara rağmen BEV'lerin daha temiz elektrik üretimi altında sera gazı emisyonlarını azaltma potansiyeline sahip olduğu yaygın olarak kabul edilmektedir (Hao, Cheng, Liu, & Zhao, 2017).…”
