Irish renewable energy developer Simply Blue has joined a North Sea consortium working on a commercial scale seaweed farm located within an offshore wind farm.

The “North Sea Farm 1 Project” involves ten hectares of water off the Netherlands coast, and is billed as the world’s first commercial scale operation of its type.

It aims to become operational this autumn when it will be deployed and seeded, with first harvest anticipated during Spring of 2025.

The project is sponsored by Amazon’s “Right Now” climate fund, and aims to help address climate action targets in Europe by “tapping into the vast, unmet potential of seaweed cultivation”.

Seaweed absorbs nitrogen, phosphorus and carbon dioxide and produces oxygen, and has been identified as part of the solution to climate change and ocean acidification.

It produces a valuable biomass with a wide range of uses from pharmaceuticals to animal feed to fertilisers.

Simply Blue Group says it has a keen interest in multiple use of wind farms, and believes that efficient use of sea space is key to working with the oceans on climate change bringing more local communities and supply chains into the transition to a low carbon economy.

“At Simply Blue Group, we want our marine projects to make a tangible difference, which is why we’re delighted to join this consortium,”Simply Blue chief executive and co-founder, said.

Eef Brouwers, project Manager of the North Sea Farm 1 initiative, welcomed Simply Blue’s involvement and said its expertise in aquaculture and offshore wind "will be valuable in the successful execution of seaweed production in an offshore wind farm for the first time”.

“The North Sea Farm 1 project aims to help the seaweed industry in scaling-up within offshore wind farms and Simply Blue Group’s capabilities in both areas make them an ideal partner,” Brouwers said.

North Sea Farmers (NSF) is an independent and not-for-profit sector organisation for the European seaweed industry. It has a member base of over 100 companies, pioneering start-ups, research institutes, NGOs and other stakeholders.

For North Sea Farm 1, NSF will head up a consortium of partner organisations extending across Europe and involved in the entire seaweed production supply chain.

This includes researchers Plymouth Marine Laboratory, Deltares and Silvestrum Climate Associates, seaweed extract manufacturers Algaia and maritime contractors Van Oord.

An aquaculture start-up is celebrating the launch of its first seaweed farm in Connemara, as vegan business magazine Vegconomist reports.

US-based Sea&Believe develops ingredients for food and cosmetics using Palmaria palmata, a red seaweed more commonly known as dillisk or dulse and one that’s recognised for its high nutritional value as well as other health benefits.

The company says it is working with a group of scientists in Galway to develop a sustainable and durable farming process for dillisk in a region notably prone to extreme weather, while also exploring new commercial applications for its natural properties.

Satellite tracking of “pongy” seaweed and algal build up has been developed by University of Galway scientists.

As The Irish Times reports, local authorities can receive complaints of seaweed accumulation, particularly from Dublin residents who may confuse it with sewage discharge.

Scientists studying the patterns of these “golden tides” – named after the colour of ascophyllum nodosum, one of the most common seaweeds on the Irish coastline - have offered their tracking software to the local authorities to help manage the issue.

The researchers from the School of Natural Sciences and Ryan Institute at the University of Galway have been studying these tides in Dublin over a seven-year period.

Led by Dr Liam Morrison and Dr Sara Harro, the University of Galway team monitored seaweed coverage at Dollymount Strand in Dublin Bay between 2016 and 2022 in relation to tides and weather.

Their BioIntertidal Mapper software analyses images from a European Space Agency satellite to help map habitats along the coastline.

It is easier to pump oil from the bottom of the ocean than to farm seaweed, according to French oceans advisor Vincent Doumeizel.

Doumeizel, from Burgundy in France, is a senior advisor on the oceans to the United Nations (UN) Global Compact, a non-binding pact encouraging businesses to adopt sustainable and socially responsible policies.

He is also director of the food programme at the Lloyd’s Register Foundation independent charity and author of “The Seaweed Revolution”, published last year, with illustrations by his daughter Neige.

He says that difficulties in obtaining licenses for seaweed farming are international, and yet the development of seaweed farming is vital to address the needs of the globe’s growing population – and contribute to carbon capture as part of climate breakdown initiatives.

“Seaweed is the healthiest food you can get on the planet”

“I had been working in the food industry for 20 years and began to realise the planet could not feed its growing population, with one billion people starving and an additional 250,000 people to feed daily,” he says.

“For the next 50 years, we are going to have to produce as much food as we ever produced as human beings over the last 10,000 years,” he continues.

“How can we do that? It won’t be possible on land. We have to look to the oceans, which cover 70 per cent of the planet but only contribute to two per cent of our food and calorie supply,” he says.

“Seaweed is the healthiest food you can get on the planet,” Doumeizel said in an interview for Wavelengths.

His book, The Seaweed Revolution, translated by Charlotte Coombe, is published by Legend Press.

A Kerry company says it uses seaweed as an additive to help crops deal with climate change stresses.

Seaweed has long been known for its fertilising qualities on areas of the Atlantic coastline, and research is currently underway here to test its benefits in animal feed in reducing methane outputs

As The Irish Times reports, BioAtlantis in Tralee, Co Kerry has been working on development of natural compounds, extracted from renewable marine and terrestrial resources, to reduce stress in crops, animals and humans by strengthening natural defence systems.

The company is now marketing a product called SuperFifty Prime to help tackle what it calls “abiotic stress”.

“Some 70 per cent of crop losses are due to abiotic stress such as cold, drought, heat, waterlogging, salinity ….. while ten per cent are due to biotic stress such as plant diseases and pathogens,” BioAtlantis research manager Dr Kieran Guinan told the newspaper.

“Even on well-managed farms with full fertiliser and pesticide programmes, crops only reach around 75 per cent of their genetic potential,” he said.

Dr Sujeeth Neerakkal, who heads up plant research at BioAtlantis, says the product is a “highly innovative oxidative stress inhibitor that works by modulating gene expression and inducing a series of stress tolerance mechanisms”.

The company says the technology helps to “prime” crops and plans to tolerate and respond more efficiently to future stresses and potential damage.

Seaweed farming is in its infancy in Ireland, however, a new strategy, BIM Irish Macro-Algal Cultivation Strategy to 2030, published by Bord Iascaigh Mhara (BIM) this week sets out a roadmap for the development of a sustainable and profitable Irish seaweed aquaculture sector.

Seaweed is increasingly being viewed as an important sustainable raw material, containing many active substances for use in different industries including, food production, pharma and agriculture. The commercial cultivation of seaweed has increased significantly in the last two decades. Annual global seaweed output is now in excess of 35 million wet tonnes, 97% of which is cultivated biomass. Most of the farmed seaweed is from Asia (China, Indonesia, Republic of Korea & Philippines).

In referring to the ambitions of the new strategy, Caroline Bocquel, CEO BIM, said: “To ensure a sustainable and economically profitable aquaculture industry in Ireland, the volume of farmed seaweed must increase. This new strategy sets out a roadmap for the seaweed sector to realise its potential. Ireland’s long coastline and clean, cold waters present the ideal conditions to cultivate seaweed, and to sustainably develop this crop that is highly resource efficient, requiring minimal resource input.”

There are currently 25 licenced seaweed farms in Ireland, located along the North West, West and South West coastline Farmed seaweeds are grown on ropes and nets, and are exceptionally fast growing plants.

Michael O’Neill, seaweed farmer, in Allihies, West Cork welcomed the new strategy and spoke of the need to unlock the potential of the seaweed sector in Ireland to meet the growing demand for sustainably produced food.

“The seaweed industry has the highest potential for growth in the Irish aquaculture sector. Ireland has always been a supplier of high-quality seaweeds for various uses, but there have been limitations, to date, on the scalability of the industry.

The advances in cultivation technology and processing, leaves Ireland extremely well positioned to become a major player in the international seaweed industry, with the demand for seaweed biomass and seaweed-based products outstripping supply for the foreseeable future.

Pure Ocean Algae welcomes the new strategy and looks forward to playing its part in the implementation of the findings of this review.”

As Cop26 continues to debate methane – with the US And EU having pledged to reduce agricultural methane outputs from ruminant livestock by upwards of 30% by 2030 – scientists at the Institute for Global Food Security (IGFS) at Queen’s University Belfast are to feed seaweed to farm animals in a bid to slash methane by at least 30%.

Seaweed has long been hailed a ‘superfood’ for humans but adding it to animal feed to reduce methane gas released into the atmosphere by ruminants' burping and flatulence is a relatively new idea. Early laboratory research at IGFS has shown promising results using native Irish and UK seaweeds.

Previous research in Australia and the USA generated headline results – up to 80% reductions in methane emissions from cattle given supplements from a red seaweed variety. These red seaweeds grow abundantly in warmer climates; however, they also contain high levels of bromoform – known to be damaging to the ozone layer. Seaweed indigenous to the UK and Ireland tends to be brown or green and does not contain bromoform.

UK and Irish seaweeds are also rich in active compounds called phlorotannins, found in red wine and berries, which are anti-bacterial and improve immunity so could have additional health benefits for animals.

Now the IGFS science is moving into the field, with trials on UK farms about to begin, using seaweed sourced from the Irish and North Seas as a feed supplement for cattle.

One 3-year project is in partnership with the UK supermarket Morrisons and its network of British beef farmers who will facilitate farm trials. The project also includes the Agrifood and Biosciences Institute (AFBI), in Northern Ireland, as a partner.

A second project sees IGFS and AFBI join a €2million, international project - led by Irish agency An Teagasc - to monitor the effects of seaweed in the diet of pasture-based livestock. Seaweed will be added to grass-based silage on farm trials involving dairy cows in NI from early 2022.

As well as assessing methane emissions of the beef and dairy cattle, these projects will assess the nutritional value of a variety of homegrown seaweeds, their effects on animal productivity and meat quality.

IGFS lead Sharon Huws, Professor of Animal Science and Microbiology within the School of Biological Sciences, said she expected the combined research to evidence a reduction in GHG emissions of at least 30%.

She said: “The science is there. It’s simply a matter of providing the necessary data and then implementing it. Using seaweed is a natural, sustainable way of reducing emissions and has great potential to be scaled up. There is no reason why we can’t be farming seaweed – this would also protect the biodiversity of our shorelines.

“If UK farmers are to meet a zero-carbon model, we really need to start putting this kind of research into practice. I hope IGFS and AFBI research can soon provide the necessary data and reassurance for governments to take forward.”

Agriculture accounts for around 10% of all UK GHG emissions. Within this, beef farming is the most carbon-intensive, with methane, which cows produce as they digest, a major component. At a NI level, methane accounts for almost a quarter of GHG emissions, with 80% of that from agriculture.

The above projects form part of the Queen's-AFBI Alliance – a strategic partnership between Queen’s University and AFBI to maximise science and innovation capacity in NI to meet global challenges, such as carbon-neutral farming.

Morrisons supermarket plans to be completely supplied by net-zero-carbon British farms by 2030. Sophie Throup, Head of Agriculture at Morrisons said: “As British farming's biggest customer, we’re very mindful of our role in supporting and inspiring the farmers we work with to help them achieve goals in sustainable farming.

“By supporting this research at Queen’s and AFBI, we are trialling this natural approach to reducing environmental emissions and improving the quality of beef products.”

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
