The importance of gas infrastructure for the German Energiewende

Thanks to sector coupling in Germany, more and more consumer sectors such as heat and transport will be switched over to entirely renewable sources of energy in the long term. A model-based analysis of the system costs across all stages of the energy supply chain shows that the existing gas infrastructure in Germany is able to make a significant contribution to achieving a comprehensive energy transition (“Energiewende”) without great expense. Preservation of the gas networks, combined with the use of “green gas” as a further final energy medium alongside electricity, will result in significantly lower overall costs than the universal electrification of all end-use applications, and it can also help to overcome customer acceptance problems.

This paper is based on a study on the German energy market carried out by Frontier Economics, IAEW, 4Management and EMCEL on behalf of the Association of German Gas Transmission System Operators (FNB Gas e.V.).
