Summary/Abstract

The introduction of biofuels from biomass for transport purposes in an energy system model shows that bioethanol and vegetable oil can compete with oil products without subsidies provided prices of imported energy carriers are high, i.e. crude oil prices around $ 100/bbl. About half of the biomass will be used for motor fuel substitutes, whose share of the final energy in the transportation sector will increase to 10% in 2030. This gives rise to a nearly 9% drop in CO2 emissions in the transportation sector as compared to an emission balance where all real local emissions are fully counted. Despite a strong enhancement of biomass and biomass fuels and quite high prices for oil and gas up to 2030, BtL products like synthetic gasoline and diesel from biomass do not play an important part in the model results unless fairly high penalties are set for CO2 emissions. In the case of global CO2 penalties below Euro 300/tco2 the use of biomass will even shift away from vehicle fuel production to biomass power plants and CHP. A CO2 penalty above Euro 100/tco2 in the transportation sector only, will, however, trigger the production of liquids and synthesis gases from biomass for use as BtL.

Summary/Abstract

This article describes the assessment of future wind power utilization for charging electric vehicles (EVs) in Germany. The potential wind power production in the model years 2020 and 2030 is derived by extrapolating onshore wind power generation and offshore wind speeds measured in 2007 and 2010 to the installed onshore and offshore wind turbine capacities assumed for 2020 and 2030. The energy consumption of an assumed fleet of 1 million EVs in 2020 and 6 million in 2030 is assessed using detailed models of electric vehicles, real world driving cycles and car usage. It is shown that a substantial part of the charging demand of EVs can be met by otherwise unused wind power, depending on the amount of conventional power required for stabilizing the grid. The utilization of wind power is limited by the charging demand of the cars and the bottlenecks in the transmission grid.
