Veröffentlichung Greenhouse - Gas - Neutrality in Germany until 2050(Umweltbundesamt, 2019) Berger, Juliane; Fee, Eric; Günther, Jens; Hain, Benno; Knoche, Guido; Purr, Katja; Deutschland. UmweltbundesamtThe success of climate and natural resource protection depends amongst others on the expansion of renewable energies. The policy paper describes the central results of the RESCUE study as well as the challenges and steps required to expand renewable energies in order to achieve greenhouse gas neutrality, and for Germany to make an appropriate contribution to the Paris Climate Agreement.

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.

Global materials extraction is accelerating and contributes significantly to GHG-emissions and other environmental pressures. Raw materials such as metals, biomass, and non-metallic minerals are central in meeting the climate targets by 2050. This study investigates possible transformation pathways towards a GHG-neutral and resource-efficient Germany by 2050 using six scenarios. In all scenarios, a transformation towards 100% renewable energy (electricity, fuels, and feedstocks) takes place until 2050. By 2050, GHG-reductions of 95% to 97% is achieved compared to 1990. Raw materials consumption can be reduced by 56% to 70% compared to 2010. However, the demand for a range of metals central to the transformation will also increase. The results show that ambitious efforts and cross-sectoral cooperation at both national and international level are required to mitigate climate change and lower raw materials demands.
