Sønderborg Utility

Sønderborg Utility has commissioned a new straw-fired heating plant in 2020 and started the process of closing the six gas-fired heating plants it replaces.

The plant consists of a 10 MW boiler, which corresponds to the entire capacity Sønderborg Utility needs to supply Nordborg and Havnbjerg.

The plant is built to run 72 hours unattended. Monitoring and remote control can be done from Sønderborg Utility's monitoring centre or employees' homes. It also has a 2,800 m3 accumulation tank, which ensures the heat supply for up to 12 hours during commissioning, optimisation and the subsequent operational support.

The patented solutions in the plant are based on Linka Energy's know-how and international experience. Therefore, the energy of the varying types, sizes and qualities of straw can be optimally utilised. After burning, farmers get the ash back and use the fertiliser value on their fields.

The plant is being built as a full contract by Linka Energy and designed to accommodate guests from Danfoss' heat production development centre, which is being built on the neighbouring site. A covered glass corridor has therefore been prepared between the buildings.

In the coming years, we, Linka Energy, will be the energy partner on the project to ensure a successful commissioning and contribute to the ambitious ProjectZero strategy to reduce the area's CO2 emissions to zero by 2029.
