Description: Germany aims at total greenhouse gas (GHG) emissions reductions of 80-95% until 2050 compared to 1990. A new scenario study by the German Federal Environment Agency (Umweltbundesamt, UBA) shows that even the ambitious 95% path is viable from a technical point of view. In a first step, it could be shown that a power supply for Germany based entirely on renewable energy sources (RES) is technically and ecologically feasible by 2050. Three radically different scenarios were developed which demonstrated that there are viable paths towards such a target. On the way to a GHG neutral society, however, considering all relevant GHG emitting sectors becomes indispensable. UBA has therefore developed a scenario for a GHG neutral Germany with emissions reductions of up to 95 % versus 1990. It becomes obvious that along with the electricity sector, particularly the heat and transport sectors must become completely CO2 neutral, as well, while others such as agriculture and certain industrial processes cannot eliminate all emissions. Whereas in Germanys current energy system storage is not yet an economic option to enhance flexibility, the demand for energy storage grows rapidly in the studied scenario. Herein, the major technology is the conversion of electric power into hydrogen, methane (Power to Gas), and liquid fuels (Power to Liquid). This allows for easy storage within the existing natural gas system plus beneficial coupling of the different sectors. The stored methane is a versatile material which can be either reconverted into electricity on demand or used as fuel for both heating and transport or as a basis for further chemical processes. Hence, in the long run PtG and PtL could be a core element of the whole energy market in a GHG neutral society.Quelle: Nowakowski, Mark; Purr, Katja:Energy Storage for a Greenhouse Gas Neutral Society: Demand and Long-Term Strategy [Elektronische Ressource] / Mark Nowakowski ; Katja Purr. - S. 1-7 : graph.
