Towards a greener gas system Energinet.dk has been working to introduce gas from renewable energy (green gas or RE gas) into the network. Biogas from liquid manure will make the gas system greener, with other RE gases to be added later. A greener gas system is a key element to converting the energy system to 100% re- newable energy by 2050. Via the gas network, RE gases can reach new markets and new applications such as transport. Small volumes of biogas have already been transported in the gas system. The biogas volumes in Denmark are expected to increase significantly in the years to come as several of the technical and market-related obstacles have been elimi- nated. This includes, among other things, the possibility of supplying biogas to the gas network, after which it can be traded and used as natural gas. In 2013, common rules on bio-natural gas trading were introduced, allowing biogas to be traded across borders. What are RE gases? Biogas and other RE gas are renewable energy from sources that are replenished on an ongoing basis. Since the biomass has absorbed the same amount of CO ² during its growth as it is emitted by burning, biogas helps to reduce CO ² emissions when it replaces fossil fuels. The RE gases that are expected to play a role in the future energy system: \\ Biogas from anaerobic degasification; \\ Biogas from thermal gasification; \\ Gas produced by means of electrolysis based on renewable energy sources. Biogas consumption Up to 2022, production of RE gases is expected to cover biogas only. In October 2012, the Danish Energy Agency assessed that the production of biogas will grow from approximately 6.6PJ in 2013 to approximately 20PJ in 2022. These energy volumes correspond to 0.17 and 0.51bcm/ year of upgraded biogas. Existing infrastructure The gas infrastructure in Denmark consists of 2 offshore pipelines sending gas from the Danish part of the North Sea to an onshore facility in Nybro and an on- shore transmission grid from west to east and from Ålborg in the north and to the Danish / German border in the south. From the landing point in Nybro and to the central point in Egtved the pipeline is doubled as there are the pipeline from Egtved to the Danish / German border and undersea lines crossing Lillebælt and Storebælt. In Dragør the Danish system is connected to Sweden. The onshore transmission grid is approximately 860km of 80 bar pipelines and 42 measuring and regulator stations. The transmission system is connected to 2 underground stor- ages and to about 17,000km of distribution grids. INFRASTRUCTURE / THIRD PARTY INFRASTRUCTURE
