Análise do poço a roda das emissões de gases do efeito estufa em veículo elétricos- revisão crítica

Abstract

The growing environmental concern has led to the search for new energy and powertrain systems. Electric vehicles (EVs) are emerging as a promising and sustainable alternative. EVs can be classified as Hybrid Electric Vehicles (HEV), Battery Electric Vehicles (BEVs), Plug-In Hybrid Electric Vehicles (PHEVs) and Fuel Cell Electric Vehicles (FCEVs).The Well-to-Wheel (WTW) analysis assesses the total primary energy consumed by the vehicle for each kWh of energy supplied to the vehicle's wheels, comprising all stages covered by the well-to-tank conversion path and, later, by the conversion of energy on board from the tank to the wheels.This study intends to carry out an analysis under the WTW perspective comparing EVs to conventional vehicles, under the viewpoint of GHG (greenhouse gas) emissions. A search will be carried out in the Scopus database, to select articles, between the years 2002 and 2020 (08/may), with the keywords: well-to-wheel and greenhouse gas emissions and electric vehicle.The electricity generation mix, the source of hydrogen production, the technologies for producing electricity or hydrogen, the losses during transmission and distribution of energy, the battery technologies, the attitude of ecological driving and the autonomy of the vehicle are all important factors that have great influence on GHG emissions. Only the introduction of electric vehicles in countries does not guarantee a reduction in GHG, being necessary to analyze the entire life cycle.
