North Sea seaweed farm to launch in the Netherlands 

NETHERLANDS – North Sea Farmers have announced the upcoming launch of North Sea Farm 1, an ambitious project to integrate the cultivation of seaweed, a protein-rich source of animal feed ingredients, with wind farming. 

North Sea Farmers is an international non-profit membership organization for the seaweed sector that works on joint investment projects and knowledge exchange on all aspects of sustainable seaweed cultivation.

This groundbreaking seaweed farming initiative is situated within the Hollandse Kust Zuid wind farm, approximately 18 kilometers off the coast of Scheveningen in the Netherlands. Production will commence later this year.

North Sea Farm 1 represents a significant leap forward in renewable energy and aquaculture. By utilizing the empty spaces between wind turbines, the project aims to expand seaweed cultivation in the North Sea, a region already heavily utilized for various maritime activities. 

The 10-hectare farm is expected to produce at least 6,000 kilograms of fresh seaweed in its first year. If successful, projections indicate the potential for cultivating up to 1 million tonnes of seaweed annually by 2040 within the current and future wind farms in the North Sea.

The project is backed by a consortium of scientific researchers and industry partners, including the Irish firm Simply Blue Group, which has a notable reputation for pushing the boundaries of offshore wind technology. 

The inclusion of Simply Blue, known for its work in floating wind technology and sustainable ocean ventures, brings additional credibility and expertise to the North Sea Farm 1 initiative. 

The project also benefits from a €1.5 (US$1.63) million grant from Amazon’s Right Now Climate Fund, which underscores the global interest in innovative climate action solutions.

“We are particularly pleased to receive the world’s first permit for a seaweed farm within a wind farm. Hollandse Kust Zuid is one of the newest wind farms in the North Sea and is relatively close to the coast, about two hours’ sailing,” said Eef Brouwers, North Sea Farmer’s general manager, in a press release.

Seaweed cultivation offers a myriad of environmental benefits. Seaweed absorbs nitrogen, phosphorus, and carbon dioxide, producing oxygen and helping to combat climate change and ocean acidification. 

This makes it a valuable tool for addressing climate targets while also providing versatile biomass for pharmaceuticals, fertilizers, and other industries. 

The North Sea Farmers envision this project as a catalyst for a new European industry, potentially creating up to 85,000 jobs in seaweed farming, production, and sales. 

Eef Brouwers, the general manager of North Sea Farmers, emphasized the importance of this project, stating, “We hope that with this project, people will become further convinced of the scaling opportunities of seaweed in the North Sea, but also of other forms of co-use such as solar, wave energy, and nature restoration.”

Despite its promising potential, integrating seaweed farming within offshore wind farms is challenging. Offshore wind sites are typically far from shore and subject to harsh conditions, making them less ideal than the calm, shallow coastal waters where seaweed is traditionally farmed.

 This has led industry experts to liken offshore seaweed farming to the “Formula 1 of seaweed production,” requiring new, high-performance approaches to ensure success.

However, the consortium behind North Sea Farm 1 is confident in its ability to overcome these challenges, leveraging years of pilot projects and innovations in seeding and harvesting technologies. 

Collaboration with organizations like the Dutch Marine Energy Centre (DMEC) further strengthens the project’s potential, as DMEC focuses on co-locating multiple offshore activities with wind farms.
