point is to establish a basic understanding of sector coupling and the role of the different sectors, particularly the inter connecting ability of the district energy system. Due to the high complexity level, it can be challenging to visualize, and that is why showcasing successful examples of sector-coupled and smart energy systems is key to build up general knowledge and inspiring cities on their journey toward sustainability. The future aspiration The sector coupling videocasts is the first series to share knowl- edge and insights. The series provides a holistic overview of the energy system and the role of district energy in particular. It provides the foundation for future knowledge sharing, focus- ing on the underlying aspects and technologies applied. In that respect, new ideas are lined up for additional series, and we look forward to sharing them with you.
Sønderborg district heating In contrast to the Copenhagen video, the Sønderborg video- cast aims to show how a small city, with 12,500 households, can successfully apply the same sector coupling principles to ensure affordable and decarbonized heat supply to its citizens. The Sønderborg District heating company supports this effort and, for example, introduced geothermal energy supplemented with sustainable biomass and electrical boilers. Now, the quest continues with extending the district heating infrastructure to other towns in the municipality and taking advantage of waste heat sources and local renewables in the area to increase the energy supply security and strengthen the local economy. In the Sønderborg videocast, we introduce the system design and the many sector coupling opportunities commonly availa- ble in smaller communities.
Charlotte Kjar, Marketing Communica- tions Manager Danfoss: “At Danfoss, we support and drive the green agenda on decarbonizing heating and cooling. We aim to engage our audience on technologies and know-how enabling the green transition. As the video format is easily accessible and more memorable than, e.g., written reports,
we are using the format to a larger extent in relation to high-level thought leader topics. This gets the message across as a short, yet concise narrative will engage with our audience in a way that text can’t achieve.” In case you have not experienced the three videocasts yet, please check out the links: Video 1: “Basic of sector coupling and the role district energy systems play”: https://www.youtube.com/watch?v=mtZ8Em5T1qI Video 2: “How the Copenhagen District Heating System supports and benefits from sector coupling”: https://www.youtube.com/watch?v=wW3eMeSp7AM Video 3: “How the Sonderborg District Heating System supports and benefits from sector coupling”: https://youtu.be/MtEom3W64UM
Tue Gejl Christensen, Project and Develop- ment Director, Sønderborg Utility: “District heating can do much more than heating the buildings. It’s an integral part of lowering the energy footprint by utilizing waste heat, e.g., from industry, and stabilizing the electrical grid with the capability to harvest heat and store it when
there is ample energy production from solar and wind.”
The three videocasts show that while the green transition is a challenging journey, it is possible, and the necessary building blocks and solutions are already available. A critical starting
