Sustainable food production at Scandinavia’s largest offshore wind farm
At Vattenfall’s Danish Kriegers Flak offshore wind farm (DKF), Danish researchers are testing the multi-use concept of producing sustainable food while generating fossil-free energy.
Short facts
- Danish Kriegers Flak, Denmark
- Marine ecosystems
- Combining aquaculture with wind farms
- 2023–2026
The project WIN@sea investigates the practical aspects of combining the aquaculture of seaweed and mussels with wind energy production.
Seaweed was successfully harvested in June 2024 at the DKF wind farm. Both mussels and seaweed are currently growing, with a second harvest event expected in May-June 2025.
The project will use the practical learnings from the pilot to assess risks and opportunities of scaling up aquaculture practise in wind farms that can help regenerate marine ecosystems in the Baltic Sea and the North Sea.
More about biodiversity
Biodiversity and nature protection are a priority at Vattenfall. It is one of the focus areas in our environmental policy and therefore also a central part in our environmental work.
