The elements of our energy system
District heating in one system
The Sønderborg area’s district heating supply is provided by 3 providers, each with their own network. However, the providers are working on interconnecting and digitizing the three networks so that we can use our district heating system in the most optimal way. For example, to feed recycled heat from industry and the Power-to-X plant into the district heating network.
The treatment plant of the future
The wastewater from a new wastewater treatment plant, expected to be completed in 2028, will play an important role in our energy supply. It is possible to extract heat from wastewater and transfer it to our district heating system. The treated wastewater can also be utilized in a Power-to-X plant and contribute to the area’s sector coupling.
A future plant will produce green fuel for aircrafts and ships, among other things. The production of green fuel is a way to store power, when we produce more power than we use. The plant reuses our treated wastewater and the CO2 we can capture from, for example, our waste incineration. And the surplus heat is fed into the district heating network.
