Abstract
Electric-vehicles have the potential for a significant substitution of diesel and gasoline vehicles, and contribute to a reduction of greenhouse gas (GHG) and particulate matter emissions. According to the European Renewable Energy Directive, the share of renewable transportation fuels should be 10% in 2020. In the project “Styrian e-mobility in 2020” the potential for reaching the target of 10% renewable fuels in 2020 has been determined by analysing different implementation scenarios. Based on a life cycle analysis, GHG and particulate matter emissions from transport services have been calculated and their potential reductions in emissions by the introduction of electric vehicles by 2020 have been determined. Reaching the European target of 10% renewable fuels in the passenger car sector by 2020 is possible with 30,700 electric-vehicles (5% of passenger cars) if the share of the additional electricity is above 50% from renewable energy and the same amount of transportation biofuel of 7% used as today.
Highlights
Electric-vehicles, as well as biofuels, have the potential for a significant substitution of diesel and gasoline vehicles. They can contribute to a reduction of greenhouse gas emissions (GHG) and particulate matter emissions in the transport sector, especially if they are powered by additional renewable electricity
In Austria and Styria the amount of transportation biofuels, especially biodiesel and bioethanol blended to gasoline and diesel, was about 7% in 2009
The maximum power demand in the Styrian electricity grid of about 1,429 MW at 11:00 clock is raised by 2,8 MW for charging 30,700 electric-vehicles, i.e. 0,19% of the maximum power demand
Summary
They can contribute to a reduction of greenhouse gas emissions (GHG) and particulate matter emissions in the transport sector, especially if they are powered by additional renewable electricity. In Austria (fuel consumption: 320 PJ/a) and Styria (fuel consumption: 43 PJ/a of which 16 PJ/a for passenger cars) the amount of transportation biofuels, especially biodiesel and bioethanol blended to gasoline and diesel, was about 7% in 2009. Due to the fact that Styria has a great additional potential of biomass and renewable electricity, biofuels and
