A new and future-proof plant is being utilised

One step closer to the vision of ProjectZero:

Sønderborg Forsyning is shutting down natural gas


The district heating's new Linka plant in Havnbjerg is running so well that Sønderborg Forsyning is now starting to shut down the natural gas-fired boiler plants.

Soon the fire will go out in Sønderborg Forsyning’s gas-fired district heating plants at Nordals. The new straw-fired district heating plant, which was commissioned in May, is operating so well that the first four can be shut down within the next month.

The straw-fired district heating plant has patented combustion technology, which not only makes heating cheaper, but also cuts out 350,000 tonnes of CO2 emissions. As a result, Sønderborg Forsyning has come closer to the goal that consumers in the region must replace individual heating based on fossil fuels with non-fossil fuel heating.

“We have been supplying heating derived from straw continuously since May. This is a clear sign that the new district heating plant has been put to good use,” says Jens Nansen Poulsen, project manager at Sønderborg Forsyning. 

The new biomass plant has minimal operational needs because it is fully automatic right from the insertion of straw to the extraction of ash. It can operate up to 72 hours without the need of employees having to be present, so that Poulsen and the other employees can instead control it from the utility company’s operations centre or from home.

 

Utilises waste

We specialise in utilising local resources in future-proof energy solutions. The straw, which provides heating to thousands of homes, is now being turned into fertiliser after incineration.

Although Danfoss’ centre for the development of heating supply has not yet been built, it has meant a lot to the construction of the new biomass plant. Its visitors must be able to walk directly through a tunnel to the district heating plant. 

We have developed several of the unique systems that make the plant a good investment and regard it as an example of future energy technology.

“We have built 15 of this type of straw-fired district heating plants in the past. Thus, it is built on our technical know-how and international experience. Everything has fallen into place. Despite the COVID-19 pandemic and the wettest winter in living memory, we have avoided delays thanks to the good working relationship. This is not least due to the good collaboration with the contractor,” says Jan Dahl Madsen, project manager at Linka Energy.

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

The plant consists of a boiler of 10 MW, which corresponds to the entire capacity that Sønderborg Forsyning needs to supply Nordborg and Havnbjerg. When we experience very cold winters again, the utility company has secured the right to buy surplus heat from Danfoss' own gas boiler.
