North Sea Farmers successfully harvested seaweed from their Netherlands wind farm seaweed operation, which received funding from Amazon’s climate fund.
Seaweed farmers have completed the first harvest at a groundbreaking commercial seaweed farm located between wind turbines in the North Sea. The North Sea Farm 1, positioned off the coast of Scheveningen in the Netherlands, represents the world’s first large-scale seaweed operation built within an offshore wind farm.
The project received €2 million in funding from Amazon’s Right Now Climate Fund and could change how the world thinks about ocean farming. The five-hectare farm sits within the ‘Hollandse Kust Zuid’ wind farm, where vessels carefully navigate between towering wind turbines to collect seaweed from underwater nets.
North Sea Farmers, the company behind the project, chose this unique location to solve a major problem facing ocean farming: finding space away from busy shipping lanes. By placing the farm between wind turbines, they discovered a way to use existing ocean infrastructure while avoiding conflicts with maritime traffic.
The wind farm seaweed harvest provides crucial information to scientists studying whether seaweed farms can pull carbon dioxide from the atmosphere and help fight climate change. Eva Faict, Amazon’s Netherlands and Belgium country manager, called the harvest “a significant moment” that proves seaweed farming among offshore wind turbines works as a business concept.
Seaweed grows much faster than land plants and absorbs carbon dioxide from seawater as it develops. When harvested, some of that carbon gets permanently removed from the ocean, potentially helping reduce the greenhouse gases that cause global warming. The process also produces a valuable crop that can be used for food, animal feed, and other products.
The farming process involves anchoring nets to the ocean floor between wind turbines. Seaweed naturally grows on these nets over several months. When ready for harvest, specialized boats navigate carefully between the massive wind turbine structures to collect the crop.
This approach solves two problems at once. Wind farms take up large areas of ocean that typically cannot be used for other purposes. By adding seaweed farming, the same ocean space now produces both renewable energy and food while potentially removing carbon from the atmosphere.
Eef Brouwers, Managing Director of North Sea Farmers, explained that the project aims to prove seaweed production within existing offshore infrastructure can work at commercial scale. The company also wants to demonstrate whether these farms can have positive long-term effects on marine life and climate change.
Three research organizations are closely monitoring the farm’s environmental impact. Plymouth Marine Laboratory, Deltares, and Silvestrum Climate Associates use satellite data and site visits to track how the seaweed farm affects the surrounding ocean environment.
Professor Ana M Queirós, who leads climate change research at Plymouth Marine Laboratory, said scientists are studying how carbon moves from seawater into seaweed and the surrounding environment. They are also examining whether the farm increases or decreases marine biodiversity in the area.
The research is particularly important because of the urgent need to find climate solutions that actually work. Many proposed climate technologies have not yet been proven at large scale. The North Sea Farm 1 project provides real-world data about whether seaweed farming can be both profitable and environmentally beneficial.
Early results from the wind farm seaweed harvest will help researchers understand the upper limits for scaling up seaweed farming. If successful, similar farms could be built in wind farms around the world, potentially creating a new industry that combines renewable energy production with carbon removal and food production.
The timing of this project reflects growing interest in ocean-based climate solutions. As countries struggle to meet climate targets, many are looking beyond land-based approaches to find new ways to reduce atmospheric carbon dioxide. Ocean farming represents one potential solution that could be scaled up quickly if the technology proves viable.

The Netherlands chose this location partly because of its extensive offshore wind infrastructure and advanced marine research capabilities. The country has been a leader in offshore wind development and has the technical expertise needed to manage complex ocean engineering projects.
For consumers, successful seaweed farming could eventually mean more sustainable food options and products made from ocean-grown materials instead of land-based agriculture. Seaweed requires no fresh water, fertilizer, or pesticides to grow, making it potentially more sustainable than many land crops.
The project’s success could influence how future offshore wind farms are designed and used. Instead of simply generating electricity, these ocean installations might become multi-use facilities that produce energy, food, and environmental benefits simultaneously.
The innovative Netherlands wind farm seaweed combination demonstrates how existing ocean infrastructure can be repurposed for multiple uses. This dual-purpose approach maximizes the value of offshore installations while minimizing environmental disruption.
The harvest represents just the beginning of what could become a major shift in how humanity uses ocean resources. If the scientific monitoring shows positive results, North Sea Farm 1 could serve as a model for Netherlands wind farm seaweed operations and similar projects worldwide.
