Foeschungszentrum Jülich - Research in Jülich 1_2013

16 Research in Jülich 1|2013 T he German federal government is backing electric vehicles in an ef- fort to protect the climate. It envis- ages that the Germans will be driving one million electric cars by 2020 and six million only ten years later. Experts for energy systems analysis at the Institute of Energy and Climate Research worked with partners from science and industry on the NET-ELAN project, investigating the possible impact of this political tar- get on the electricity grid, the energy in- dustry and the climate. According to them, the use of electric vehicles would lead to a reduction of al- most 5% in the consumption of mineral oil products in the entire transport sector by 2030. The result: the emission of the greenhouse gas CO2 would be reduced by between five and eleven million tonnes in Germany. “This figure has such a wide range because the electricity used to charge the batteries of the elec- tric vehicles comes from wind energy and the amount of electricity it generates fluctuates depending on weather condi- tions,” explains Jochen Linßen, lead au- thor of the NET-ELAN final report. The study also verifies that the mar- ket introduction of electric cars as Six million electric cars are expected to be on the road in Germany in 2030. According to a comprehensive study performed by a team headed by Jülich scientist Jochen Linßen, this would not necessitate any expansion of the country’s system of generating electricity. planned by the federal government is technically feasible. If the cars are re- charged at defined times, Germany will not have to construct any additional power plants or adapt the electricity grid. ELECTRICITY FROM WIND ENERGY? In another respect, however, the ca- pacity of the planned grid will not be suf- ficient. Excess electricity from wind en- ergy can only be transported in part to the conurbations and thus to the charg- ing stations for electric cars. The excess electricity comes from planned wind Recharging After Midnight: Study on Electromobility
