The dream of constructing the world’s first industrial scale seaweed farm inside an offshore wind farm edged a little bit nearer to actuality final week, when the Irish agency Merely Blue Group stamped its seal of approval on the North Sea Farm 1 venture. The rough-and-tumble surroundings of an offshore wind array just isn’t the simplest place to determine a brand new aquaculture enterprise, however the crowded North Sea gives seaweed farmers with few different choices. A bunch of seaweed trade stakeholders is decided to make it occur, and if all goes in accordance with plan the thought will unfold to wind farms all around the North Sea.

Offshore Wind Skilled Likes New Seaweed Farm

North Sea Farm 1 is a creation of the commerce group North Sea Farmers. The plan requires a brand new seaweed operation to be deployed and seeded in an offshore wind farm, within the North Sea off the coast of the Netherlands.

The preliminary section requires the seaweed to occupy a 10-hectare web site, or about 100,000 sq. meters. Deployment and seeding are anticipated this fall, with the primary harvest to come back proper after within the spring of 2025. The primary-year crop alone is anticipated to whole 6,000 kilograms.

The seal of approval from Merely Blue is vital, as a result of it lends extra credibility to a seemingly inconceivable job (extra on that in a second). Merely Blue has already established a popularity for pushing that boundaries of offshore wind, together with floating wind know-how. The corporate has additionally expressed an curiosity in leveraging wind generators as anchors for different offshore industrial ventures.

“Merely Blue Group is concentrated on changing fossil fuels with clear ocean vitality, eradicating CO₂ from the environment, and growing sustainable sources of protein, whereas attracting funding into coastal communities,” the corporate explains.

“It has a eager curiosity in a number of use of wind farms and believes that environment friendly use of sea house is vital to working with the oceans on local weather change and convey extra native communities and provide chains into the transition to a low carbon financial system,” they add.

So far, a lot of the offshore wind multi-use exercise includes piggybacking photo voltaic panels, wave vitality converters, and inexperienced hydrogen techniques onto the generators. Fish farming can also be starting to emerge as a co-location alternative.

The seaweed angle is one other comparatively new growth, and evidently Merely Blue wish to get out forward of the competitors. Final summer time the agency cemented a relationship with the Norwegian aquaculture firm Arctic Seaweed, geared toward growing prototype seaweed farms at offshore wind websites. The North Sea venture gives Merely Blue with a possibility to speed up into industrial scale.

In a press assertion, Merely Blue co-founder and CEO Hugh Kelly emphasised the multi-use angle. “We recognise that seaweed cultivation is a beneficial software in tackling local weather change and supporting our oceans.  We imagine that in time offshore wind farms can have a number of makes use of, with seaweed manufacturing being one among them.”

How Offshore Wind Can Kickstart The European Seaweed Business

As for why trouble establishing a seaweed farm far offshore, North Sea Farmers anticipates {that a} native, dependable supply of top quality seaweed would assist the European seaweed product trade scale up. Thus far, Europe’s reliance on the abroad provide chain has been an impediment to progress.

One other new hurdle additionally arose on the availability aspect, when The Netherlands determined to prioritize offshore wind within the North Sea over different industries on the heels of the 2015 Paris Accord on local weather change. That left little room for the seaweed trade to develop.

In 2020, North Sea Farmers lastly come across the thought of becoming a member of forces with the wind trade. “And with seaweed we noticed (and nonetheless see) a vibrant future for scale-up of manufacturing in offshore wind farms; safer and co-usage of in any other case unused North Sea house,” they clarify.

“That’s why we concluded in 2020 that as seaweed sector organisation we would have liked to 1) help the scale-up of domestically produced seaweed and a couple of) attempt to give higher visibility to the seaweed sector within the stakeholder discussions on the longer term utilization of the (Dutch) North Sea.”

By 2021 North Sea Farmers had organized a consortium to set the wheels in movement for North Sea Farm 1, consisting of the impartial analysis organizations Deltares and Plymouth Marine Laboratory, the local weather adaptation agency Silvestrum Local weather Associates, seaweed extract producers Algaia, and maritime contractor Van Oord.

The mix of seaweed farming and offshore wind additionally caught the eye of the Amazon Proper Now Local weather Fund, which offered North Sea Farmers with a €1.5 million grant final 12 months assist get the venture in gear, starting with the 10-hectare web site.

As well as, North Sea Farmers works with DMEC, the Dutch Marine Vitality Centre. Although wave and tidal vitality are the primary focuses of DMEC, the group can also be pursuing actions to co-locate a number of offshore actions with wind farms.

North Sea Farm 1 can also be benefiting from a number of years’ value of pilot tasks within the North Sea. “Members equivalent to Murre Applied sciences and Boeg Nautic have constructed seeding and harvesting machines that may assist with protected and environment friendly offshore manufacturing,” North Sea Farmers notes.

The Method 1 Of Seaweed Farming

The thought of co-locating seaweed farming with offshore wind appears easy sufficient, contemplating that seaweed farming by nature is an offshore operation. Nonetheless, as our buddies over on the World Wildlife Fund level out, a lot of the worldwide seaweed provide comes from comparatively calm, shallow coastal waters. Wind farms are situated farther offshore, the place the situations for seaweed farming are more difficult.

North Sea Farmers cites The Seaweed Firm founder Joost Wouter, who has described seaweed farming at an offshore wind web site because the “Method 1 of seaweed manufacturing.” Method 1 racing arguably has nothing to do with seaweed. Nonetheless, the primary level is that the offshore wind web site requires a brand new, high-performance method to seaweed farming.

“It’s far, it’s deep, it’s harmful and it’s costly,” North Sea Farmers explains.

Issue apart, the group is assured that North Sea Farm 1 will kickstart a brand new trade in Europe. The group’s Supervisor of Farming and Expertise, Eef Brouwers, anticipates that 85,000 new jobs in seaweed farming, manufacturing, and gross sales might consequence if different offshore wind farms lend their stake within the North Sea to the seaweed trade.
