Researchers are exploring multiple uses for wind parks far out at sea, such as producing fresh seafood
Workers aboard a small boat check lines of seaweed and mussels crops at Kriegers Flak offshore wind farm, about 15 kilometers off the Danish coast, Baltic Sea, Denmark, Tuesday June 18, 2024. In a small boat bobbing in the waves between towering offshore, researchers in Europe’s Baltic Sea reach into the frigid water and remove long lines stretched between the pylons onto which mussels and seaweed are growing.
“There’s an increasing competition for space on land and in the sea," said Aarhus University senior scientist Annette Bruhn, who leads the project. “We can, in one area, produce both fossil-free energy and food for a growing population.” “Seaweed and mussels are low trophic aquaculture crops, which means that they can be produced without the use of fertilizers. They take up nutrients from the sea and produce healthy foods,” Bruhn said.
Researchers say now is the time to develop guidelines to encourage companies to plan for multiple uses of the ocean as European nations massively ramp up production ofIn 1991, Denmark became the first country in the world to install a commercial offshore wind park. More than 30 years later, nearly half of the Danish electricity production derives from wind turbines.
Offshore projects have been criticized for damage caused to the sea floor during construction, noise pollution and nowMeanwhile, the large boulders laid at the base of the turbines to prevent erosion can also act as artificial reefs attracting more marine life and protect from large-scale fishing operations.

Beneath offshore wind turbines, researchers grow seafood and seaweedResearchers are exploring multiple uses for wind parks far out at sea, such as producing fresh seafood. A four-year project that started in 2023 at Scandinavia's largest wind farm off Denmark's east coast is showing signs of early success with its first harvest of seaweed 18 months later.
