The Impact of E‐Mobility in a Future Energy System Dominated by Renewable Electricity

Battery and fuel cell electric cars have been identified as solution to meet the target of reducing greenhouse gas emissions by 80 to 95 % before 2050, however they will also impact the increasingly renewable electricity‐based energy system. A numerical case study is conducted for a prototypical station consisting of hydrogen refueling equipment for fuel cell electric vehicles and charging points for battery electric vehicles located in Northern Germany with rather good wind but limited photovoltaics conditions. Major conclusions for the impact of both e‐mobility concepts on the energy system are drawn. The integration of battery electric vehicles (BEVs) into today's electricity system requires also an understanding of the role of energy storage for growing shares of renewable electricity. Results from a focused analysis are presented in how far BEVs could add to and hydrogen fuel cell vehicles relax the challenges for the electricity system.
