First Commercial-Scale Seaweed Farm Between Wind Turbines Fully Operational In Netherlands
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The world’s first commercial-scale seaweed farm within the Hollandse Kust Zuid offshore wind farm in the Netherlands is fully operational.
These initial three paragraphs fill out the details.
According to the non-profit organisation North Sea Farmers (NSF), the final deployment step was completed one week ago by deploying the seeded substrate.
North Sea Farm 1, initiated by NSF 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.
The seaweed farm is located within the Hollandse Kust Zuid wind farm, nearly 22 kilometres off the coast of Scheveningen. The 1.5 GW project is owned by Vattenfall, BASF, and Allianz.
I find this an interesting concept.
I can remember reading in the Meccano Magazine in the 1950s, about the production of alginates from seaweed in Scotland.
Surprisingly, Wikipedia has very little on alginates, except for this illuminating Wikipedia entry for alginic acid.
This is the opening paragraph.
Alginic acid, also called algin, is a naturally occurring, edible polysaccharide found in brown algae. It is hydrophilic and forms a viscous gum when hydrated. When the alginic acid binds with sodium and calcium ions, the resulting salts are known as alginates. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular, or powdered forms.
But it does appear that the Scottish production of alginates is very much of the past. Unless someone else can enlighten me!
Perhaps Scottish seaweed farming can be revived to produce alginates, which appear to have a surprising number of uses, as this section of the Wikipedia entry shows.
Alginates do appear to be remarkably useful.
These are a few uses.
- As of 2022 alginate had become one of the most preferred materials as an abundant natural biopolymer.
- Sodium alginate is mixed with soybean protein to make meat analogue.
- They are an ingredient of Gaviscon and other pharmaceuticals.
- Sodium alginate is used as an impression-making material in dentistry, prosthetics, lifecasting, and for creating positives for small-scale casting.
- Sodium alginate is used in reactive dye printing and as a thickener for reactive dyes in textile screen-printing.
- Calcium alginate is used in different types of medical products, including skin wound dressings to promote healing,
Alginates seem to have some rather useful properties.
Four years ago, I tripped over in my bedroom, which I wrote about in An Accident In My Bedroom. I wonder if the Royal London Hospital used calcium alginate skin dressings to restore my hand to its current condition.
Paul Daniels would have said, “It’s magic!”
In the future these dressings may be produced from UK-produced seaweed.
Project Launches To Pair Offshore Wind With Sustainable Food Production
Note that it’s a little over a fortnight to April Fool’s Day!
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Win@Sea, a new collaboration between Vattenfall and Danish universities and companies, will investigate how to produce offshore wind power and sustainable food – all while improving the marine environment and biodiversity in the same marine area.
This is the first paragraph.
The partners will look into whether an offshore wind farm could simultaneously produce fossil-free electricity and sustainable food while also contributing positively to biodiversity in the same area.
But this report is not alone, in using the sea as a farm.

It sounds to me like a case of great minds thinking alike.
Amazon Finances First-Ever Commercial-Scale Seaweed Farm Located Between Offshore Wind Turbines
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Multinational technology company Amazon is funding the world’s first commercial-scale seaweed farm located between offshore wind turbines
This paragraph details the project.
The North Sea Farm 1 will be located in a wind farm off the coast of the Netherlands, designed to test and improve methods of seaweed farming, while researching the potential of seaweed to sequester carbon.
Seaweed is all the rage at the moment, since Notpla won Prince William’s Earthshot Prize, with their packaging made from seaweed.
It sounds to me, that as Amazon probably create more need for packaging, than any company in the world, there could be an almighty coming together, which will create a lot of environmentally-friendly ideas.
Brown Seaweed Could Remove 550 Million Tons Of Carbon
The title of this post, is the same as that of this article on the Carbon Herald.
This may seem like a story that has arrived a few months early.
But the report does come from the respect Max Planck Institute for Marine Microbiology.
The research is detailed on this page on their web site, which is entitled Slime For The Climate, Delivered By Brown Algae.
It is introduced by this sub-heading.
In form of fucoidan, brown algae could remove up to 550 million tons of carbon dioxide from the atmosphere every year.
Which is followed by this paragraph.
Brown algae take up large amounts of carbon dioxide from the air and release parts of the carbon contained therein back into the environment in mucous form. This mucus is hard to break down for other ocean inhabitants, thus the carbon is removed from the atmosphere for a long time, as researchers at the Max Planck Institute for Marine Microbiology in Bremen now show. They reveal that the algal mucus called fucoidan is particularly responsible for this carbon removal and estimate that brown algae could thus remove up to 550 million tons of carbon dioxide from the air every year – almost the amount of Germany’s entire annual greenhouse gas emissions.
Note that fucoidan has a Wikipedia entry.
The page says this about brown algae.
Brown algae are true wonder plants when it comes to absorbing carbon dioxide from the air.
It does seem to me that the Germans are on to something.
The Plans For Giant Seaweed Farms In European Waters
The title of this post, is the same as that of this article on the BBC.
The article describes how the Dutch are developing the growing and harvesting of seaweed.
This is all fascinating stuff and reminds me of reading of a company called Alginate Industries in the Meccano Magazine in the 1950s.
I can’t find much about the company, except that they were taken over by Merck & Co in 1979.
The Wikipedia entry for alginic acid, gives this information on alginates.
Alginates are refined from brown seaweeds. Throughout the world, many of the Phaeophyceae class brown seaweeds are harvested to be processed and converted into sodium alginate. Sodium alginate is used in many industries including food, animal food, fertilisers, textile printing, and pharmaceuticals. Dental impression material uses alginate as its means of gelling. Food grade alginate is an approved ingredient in processed and manufactured foods.
I remember the Meccano Magazine saying that alginates were an important food additive and UK production came from the North of Scotland.
This page on the Secret Scotland wiki gives details of current alginate production in Scotland.
Has Wikipedia replaced the Meccano Magazine, as a source of information for scientifically-inquisitive children?
