Furthermore, a slight decrease in the use of natural gas and heat pumps with increasingbattery capacity is experienced.TWh2524232221201918171615Coal3 4,5 6 7,5 9 11,5 15BEV 15BEV 29BEV 43BEV 58BEV 72PHEV (kWh)Figure 4 Electricity generation on coal in Finland, 2030 (TWh)In Germany investments are in coal plants only. The majority of the generation is onnuclear, coal, and lignite. Both coal and lignite is increasing with increasing batterycapacities. It is interesting though, that with an increase in the BEVs battery capacity, theelectricity generation on coal is decreasing as can be seen from Figure 5. Furthermore,the largest increase is experienced with the increase from 3 to 6 kWh batteries in thePHEVs.TWh460Coal450440430420410BEV 15BEV 29BEV 43BEV 58BEV 724003 4,5 6 7,5 9 11,5 15PHEV (kWh)Figure 5 Electricity generation on coal in Germany, 2030 (TWh)Usage of lignite decreases up to a battery level of 4.5 kWh for the PHEVs and increasesotherwise (Figure 6). The level of renewable energy is 0%, due to resources and maybealso Germany only being allowed transmissions with the other Nordic countries.Risø International Energy Conference 2011 Proceedings Page

Investments arealmost non-changing. Changes in the use of natural gas are experienced (Figure 7). Asmall increase is seen up to 6 kWh in the PHEVs and after that, the use of natural gas isgenerally decreasing. Furthermore, the use is decreasing with increasing batterycapacities in the BEVs. All of this is resulting in a level of approx. 71% of renewableenergy in Sweden in all scenarios.TWh10,90,80,70,60,50,40,30,20,10Natural Gas3 4,5 6 7,5 9 11,5 15BEV 15BEV 29BEV 43BEV 58BEV 72PHEV (kWh)Figure 7 Electricity generation on natural gas in Sweden, 2030 (TWh)CO2-emissions from electricity generationCO2-emissions increase for Germany and Finland with increasing battery capacity anddecrease in Denmark and Sweden.
