First commercial implementation
NORTH SEA FARM 1
In collaboration with Simply Blue Group, Van Oord, Algaia, and Amazon, we opened the world’s first commercial-scale seaweed farm within the offshore wind farm ‘Hollandse Kust Zuid’ (HKZ), located about 18 kilometres off the coast of Scheveningen in the North Sea. North Sea Farm #1 initiated by North Sea Farmers with funding from Amazon’s Right Now Climate Fund, is a floating farm located in the open space between wind turbines where seaweed production can be tested and improved. In parallel, scientific research aims to validate the carbon sequestration potential of seaweed farms and measure biodiversity impacts.
