A harbour near Melbourne in Australia is probing the potential of its natural tides to develop a new kind of renewable energy hub.

As the Bellarine Times reports, Queenscliff Harbour has partnered with the non-profit Southern Ocean Environmental Link and tidal turbine maker Altum Green Energy to install a device near the harbour’s marina.

The area of Port Phillip Heads, also known as The Rip, is at the narrow entrance to the large bay on which Melbourne lies to the northeast.

Its large tidal flows make it a treacherous stretch for boating and shipping, but a potentially rich one for generating power from the sea.

The joint project is currently collecting measurements at the location to determine its potential and best positioning for the Altum turbine, which is designed to operate in slow-flowing waters such as at ports and bridges, rivers, canals and islands.

Exploring development of the “next generation” tidal energy technology is the theme of a new project initiated by NUI Galway (NUIG).

The university says the tidal energy project is part of its “Global Challenges” programme, a targeted research initiative to tackle six of the globe’s most pressing issues.

The project will focus on new technology and tidal turbine blades, site modelling, and the assessment of climate change impact and extreme events on same.

It will include an economic appraisal of tidal energy and the investigation of societal attitudes; and stakeholder engagement to better understand the needs and concerns of tidal energy developers, local authorities and the coastal communities.

It will also research systems to assess the interactions of tidal energy infrastructure with wildlife.

Five PhD researchers will be recruited for the project.

Globally, the tidal energy resource is estimated at more than 1200 terawatts per annum - a unit of power equal to one trillion watts.

The world uses 17.7 terawatts a year, according to the NUIG researchers.

The project will be led by Prof Jamie Goggins, professor of civil engineering, MaREI Centre, Ryan Institute and School of Engineering at NUIG.

He said the project “will engage with multiple stakeholders - including the people living in the coastal communities - to unlock the potential benefits for them in our drive to decarbonise the economy”.

“The just transition is crucial in the work towards decarbonisation. So too is the importance placed on biodiversity and how we enhance the health and resilience of our ocean and coastal communities,”he said.

“ Our aim in the tidal energy project is to create a blueprint to simultaneously achieve these ambitions,”Prof Goggins added.

The NUI Galway Global Challenges fund is part of the university’s new Research and Innovation Strategy 2021-26.

It has six areas of focus - antimicrobial resistance, decarbonisation, democracy, food security, human-centred data, and ocean and coastal health.

#SeaPower - Northern Ireland is well placed to capitalise on the growing trend towards renewable energy thanks to its unique tidal resources, according to a leading researcher in the field.

Dr Carwyn Frost of Queen’s University Belfast tells Emily McDaid of local tech incubator Catalyst Inc that the Narrows between Strangford Lough and the Irish Sea have the perfect conditions to harness the power of the sea’s tides — in shallow waters away from ocean swell, and more accessible than similar sites in the far north of Scotland.

The area was previously home to the world’s first tidal power station in the form of the SeaGen turbine, and has since been a test site for new projects such as the PowerKite developing the next generation of tidal energy devices.

#SeaPower - A prototype tidal energy turbine project in the Shannon Estuary has received almost €100,000 in funding for further development, as the Limerick Post reports.

GKinetic has been testing a scale prototype of its new hydrokinetic turbine for the last year, at a purpose-built facility in Limerick Docks set up in tandem with the Shannon Foynes Port Company.

The new funding of €99,562 from the Sustainable Energy Authority of Ireland’s (SEAI) Prototype Development Fund will support testing on an improved prototype from August for a six-week period, as the company ramps up plans to scale up the design to a 250kW tidal device.

GKinetic’s technology is already being commercialised by fellow Co Limerick company DesignPro, who secured funding earlier this year under the Horizon 2020 project to test its own river energy devices at scale.

OpenHydro, the Irish based tidal energy company and part of DCNS Energies, has appointed Mr Patrick Gougeon as their new Chief Executive Officer. The appointment signals the company’s ongoing drive towards commercialisation of its tidal technology and follows the launch of DCNS Energies, a subsidiary of the DCNS Group which recently secured €100m in investment.

Mr Gougeon joined OpenHydro at the start of January 2017, having previously held the position of CEO of Colibrys, a high-technology industrial company based in Switzerland. He is an engineer from the French Ecole Centrale de Lille and holds an MBA from the HEC School of Management in Paris.

With over twenty years’ experience in delivering global technological projects and transforming organizations in the industrial sector, Mr Gougeon’s senior management career to date has encompassed roles including consultancy in strategy and organisation in McKinsey & Company, as well as change management, international business development, industrial and program management as a successful executive in the Thales and Safran groups.

Thierry Kalaquin, Senior Vice President of Energies at DCNS, said: “We are delighted to be welcoming Patrick to this role, following a successful year in 2016, which saw us deliver significant tidal technology development. We now look forward to moving towards a fully commercial tidal energy solution and servicing our global portfolio of projects.”

Operating out of OpenHydro’s Dublin offices and its Technical Centre in Greenore, Co. Louth, Mr Gougeon heads up a business that has strong plans to expand both locally and internationally.
Commenting on his appointment, Patrick Gougeon said: “I am really looking forward to taking up the challenge to lead OpenHydro’ s team during this exciting phase of its’ evolution. My immediate focus is to ensure that we are well placed for the next stage of growth and opportunities that lie ahead, with the right people, organization, technology and partners in place.”

James Ives, CEO at tidal energy company OpenHydro will speaking tomorrow at the Ocean Energy Europe Conference being held this week in Croke Park in Dublin. Ives will tell how the Irish marine renewable firm is to be the global leader in tidal solutions, profitably delivering economic marine renewable energy.

The Department of Communications says that €4.5m. will be allocated to ocean energy research in Ireland under Budget provisions next year. Total allocation for energy efficiency and renewable energy onshore and offshore next year is €68m. €9 million is being provided for geoscience initiatives including the INFOMAR and TELLUS programmes, which will support expanded geoscience research in Ireland’s offshore and onshore.

OpenHydro, a DCNS company, based in Ireland, is a technology business that designs and manufactures marine turbines to generate renewable energy from tidal streams. The company's vision is to deploy farms of tidal turbines under the world's oceans - silently and invisibly generating electricity at no cost to the environment. OpenHydro's technology enables the ocean's immense energy to be harnessed for the benefit of all. The electricity produced is completely renewable since it relies on tides that are created by the gravitational effect of the sun and moon. Through this innovative technology, OpenHydro will extract energy from the oceans in an economically viable and environmentally sensitive manner.

OpenHydro has developed the innovative Open-Centre Turbine technology which is a shrouded, horizontal-axis turbine. Simplicity is the key advantage of this technology: manufactured from a small number of components and with only one single moving part (the rotor). There is no need for oils, seals or a gearbox and this not only reduces the requirement for maintenance but ensures reliable performance in the harsh environment that is the World’s oceans. The turbines, each supported on a subsea structure, are placed directly onto the seabed, deep enough so as not to pose a hazard to shipping traffic overhead and the standard OpenHydro product has a diameter of 16m and is rated at 2MW. OpenHydro has also developed a patented method to install the Open-Centre Turbines, allowing all deployments to be completed in a single tidal cycle; less than 6 hours.

OpenHydro is at the fore-front of the tidal industry, with nearly one gigawatt of development in progress across multiple sites in Europe and North America.

#SeaPower - What's been described as the world's largest planned tidal energy scheme has been given the green light by its financiers, with construction set to begin off the northern Scottish coast in the new year, as The Guardian reports.

Previously detailed last month on Afloat.ie, the MeyGen project – comprising 269 turbines on the seabed off Caithness in the far north of mainland Scotland – will see onshore construction get under way next month after developers Atlantis Resources satisfied the conditions to draw down funds from The Crown Estate of Scottish Enterprise.

MeyGen aims to harness the strong currents at the Ness of Quoys in Pentland Firth to generate energy at levels "on a part with wind turbines" but hidden from view beneath the waves - with the first power from the sea to be delivered to Britain's national grid by 2016.

#PowerFromTheSea - The next big renewable energy turbine farm could be underwater off the coast of Scotland, as MailOnline reports.

Scottish firm MayGen has big plans to install a £51 million (€65.2 million) underwater turbine project to harness the powerful currents of their country's coastal waters.

This new project, earmarked for Pentland Firth at Caithness in the far north of mainland Scotland, follows separate plans to install the world's largest tidal power facility in the Sound of Islay.

MayGen - which has just won an award for its parent company Atlantis Resources for its "significant contribution" to the marine renewables industry – says its state-of-the-art technology is "on a par with wind turbines" in terms of productivity, but would be hidden from the view of those who find the larger land-based wind farms unsightly.

The Pentland Firth project will be the new design's proving ground, with hopes that it will generate power for nearly half a million homes upon completion in 2020.

#POWER FROM THE SEA - Marine-based renewable energy projects could be introduced without a damaging impact on marine wildlife, according to a new briefing paper from Friends of the Earth.

Business Green reports on the paper from the environmental campaign group, written by marine ecologist Martin Attrill of Plymouth University's Marine Institute, which draws together research on the biodiversity impact of offshore wave energy, tidal energy and wind power schemes.

Attrill found that the deployment of sea energy arrays could ultimately benefit many marine species by reducing the effects of fishing activity, and even acting as reefs to attract new sea life.

He cites the example of a grey seal colony in Strangford Lough that has steered clear of a nearby tidal turbine over the three years of its operation in the lough.

However, Business Green says the report makes clear that the deployment of such projects "must be done sensitively", noting that any negative impact on biodiversity "would be significantly lower than the damage done to marine wildlife by rising sea levels caused by climate change".

#POWER FROM THE SEA - A €9 million Europe-wide wave energy trial programme is one of the key elements of a new Government programme designed to transform Ireland as a maritime nation.

According to The Irish Times, University College Cork's Hydraulics and Maritime Research Centre will run testing of wave energy, tidal energy and offshore wind energy devices across a network of sites in 12 European countries participating in the new marine renewables infrastructure network Marinet.

Irish test sites in the network include the national ocean test facility in Cork and centres operated by the Sustainable Energy Authority of Ireland (SEAI) at Galway Bay and Belmullet.

The UCC centre also forms part of the new Irish Maritime and Energy Resource Cluster (IMERC), launched last Friday by Taoiseach Enda Kenny.

The cluster comprises UCC, the Irish Naval Service, Cork Institute of Technology and the National Maritime College of Ireland with the initial aim of creating 70 new research jobs by 2014 in the areas of wave energy, green shipping and sustainability of ocean resources.

IMERC director Dr Val Cummins said: “The aim of IMERC is to promote Ireland as a world-renowned research and development location that will unlock Ireland’s maritime and energy potential."

Aquaculture Information

Aquaculture is the farming of animals in the water and has been practised for centuries, with the monks farming fish in the middle ages. More recently the technology has progressed and the aquaculture sector is now producing in the region of 50 thousand tonnes annually and provides a valuable food product as well as much needed employment in many rural areas of Ireland.

A typical fish farm involves keeping fish in pens in the water column, caring for them and supplying them with food so they grow to market size. Or for shellfish, containing them in a specialised unit and allowing them to feed on natural plants and materials in the water column until they reach harvestable size. While farming fish has a lower carbon and water footprint to those of land animals, and a very efficient food fed to weight gain ratio compared to beef, pork or chicken, farming does require protein food sources and produces organic waste which is released into the surrounding waters. Finding sustainable food sources, and reducing the environmental impacts are key challenges facing the sector as it continues to grow.

Salmon is the most popular fish bought by Irish families. In Ireland, most of our salmon is farmed, and along with mussels and oysters, are the main farmed species in the country.

Aquaculture in Ireland

  • Fish and shellfish are farmed in 14 Irish coastal counties.
  • Irish SMEs and families grow salmon, oysters, mussels and other seafood
  • The sector is worth €150m at the farm gate – 80% in export earnings.
  • The industry sustains 1,833 direct jobs in remote rural areas – 80% in the west of Ireland
  • Every full-time job in aquaculture creates 2.27 other jobs locally (Teagasc 2015)
  • Ireland’s marine farms occupy 0.0004% of Ireland’s 17,500Km2 inshore area.
  • 83% of people in coastal areas support the development of fish farming
  • Aquaculture is a strong, sustainable and popular strategic asset for development and job creation (Foodwise 2025, National Strategic Plan, Seafood
  • Operational Programme 2020, FAO, European Commission, European Investment Bank, Harvesting Our Ocean Wealth, Silicon Republic, CEDRA)
    Ireland has led the world in organically certified farmed fish for over 30 years
  • Fish farm workers include people who have spent over two decades in the business to school-leavers intent on becoming third-generation farmers on their family sites.

Irish Aquaculture FAQs

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants, and involves cultivating freshwater and saltwater populations under controlled conditions- in contrast to commercial fishing, which is the harvesting of wild fish. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats. Particular kinds of aquaculture include fish farming, shrimp farming, oyster farming, mariculture, algaculture (such as seaweed farming), and the cultivation of ornamental fish. Particular methods include aquaponics and integrated multi-trophic aquaculture, both of which integrate fish farming and plant farming.

About 580 aquatic species are currently farmed all over the world, according to the UN Food and Agriculture Organisation (FAO), which says it is "practised by both some of the poorest farmers in developing countries and by multinational companies".

Increasing global demand for protein through seafood is driving increasing demand for aquaculture, particularly given the pressures on certain commercially caught wild stocks of fish. The FAO says that "eating fish is part of the cultural tradition of many people and in terms of health benefits, it has an excellent nutritional profile, and "is a good source of protein, fatty acids, vitamins, minerals and essential micronutrients".

Aquaculture now accounts for 50 per cent of the world's fish consumed for food, and is the fastest-growing good sector.

China provides over 60 per cent of the world's farmed fish. In Europe, Norway and Scotland are leading producers of finfish, principally farmed salmon.

For farmed salmon, the feed conversion ratio, which is the measurement of how much feed it takes to produce the protein, is 1.1, as in one pound of feed producing one pound of protein, compared to rates of between 2.2 and 10 for beef, pork and chicken. However, scientists have also pointed out that certain farmed fish and shrimp requiring higher levels of protein and calories in feed compared to chickens, pigs, and cattle.

Tilapia farming which originated in the Middle East and Africa has now become the most profitable business in most countries. Tilapia has become the second most popular seafood after crab, due to which its farming is flourishing. It has entered the list of best selling species like shrimp and salmon.

There are 278 aquaculture production units in Ireland, according to Bord Iascaigh Mhara (BIM) *, producing 38,000 tonnes of finfish and shellfish in 2019 and with a total value of €172 million

There are currently almost 2,000 people directly employed in Irish aquaculture in the Republic, according to BIM.

BIM figures for 2019 recorded farmed salmon at almost 12,000 tonnes, valued at €110 million; rock oysters reached 10,300 tonnes at a value of €44 million; rope mussels at 10,600 tonnes were valued at €7 million; seabed cultured mussels at 4,600 tonnes were valued at €7 million; "other" finfish reached 600 tonnes, valued at €2 million and "other" shellfish reached 300 tonnes, valued at €2 million

Irish aquaculture products are exported to Europe, US and Asia, with salmon exported to France, Germany, Belgium and the US. Oysters are exported to France, with developing sales to markets in Hong Kong and China. France is Ireland's largest export for mussels, while there have been increased sales in the domestic and British markets.

The value of the Irish farmed finfish sector fell by five per cent in volume and seven per cent in value in 2019, mainly due to a fall on salmon production, but this was partially offset by a seven per cent increased in farmed shellfish to a value of 60 million euro. Delays in issuing State licenses have hampered further growth of the sector, according to industry representatives.

Fish and shellfish farmers must be licensed, and must comply with regulations and inspections conducted by the Sea Fisheries Protection Authority and the Marine Institute. Food labelling is a function of the Food Safety Authority of Ireland. There is a long backlog of license approvals in the finfish sector, while the Department of Agriculture, Food and Marine says it is working to reduce the backlog in the shellfish sector.

The department says it is working through the backlog, but notes that an application for a marine finfish aquaculture licence must be accompanied by either an Environmental Impact Statement (EIS) or an Environmental Impact Assessment Report (EIAR). As of October 2020, over two-thirds of applications on hand had an EIS outstanding, it said.

The EU requires member states to have marine spatial plans by 2021, and Ireland has assigned responsibility to the Department of Housing, Planning and Local Government for the National Marine Planning Framework (NMPF). Legislation has been drawn up to underpin this, and to provide a "one stop shop" for marine planning, ranging from fish farms to offshore energy – as in Marine Planning and Development Management Bill. However, the Department of Agriculture, Food and Marine confirmed last year that it intends to retain responsibility for aquaculture and sea-fisheries related development – meaning fish and shellfish farmers won't be able to avail of the "one stop shop" for marine planning.

Fish and shellfish health is a challenge, with naturally occurring blooms, jellyfish and the risk of disease. There are also issues with a perception that the sector causes environmental problems.

The industry has been on a steep learning curve, particularly in finfish farming, since it was hailed as a new future for Irish coastal communities from the 1970s – with the State's Electricity Supply Board being an early pioneer, and tobacco company Carrolls also becoming involved for a time. Nutrient build up, which occurs when there is a high density of fish in one area, waste production and its impact on depleting oxygen in water, creating algal blooms and "dead zones", and farmers' use of antibiotics to prevent disease have all been concerns, and anglers have also been worried about the impact of escaped farmed salmon on wild fish populations. Sea lice from salmon farmers were also blamed for declines in sea trout and wild salmon in Irish estuaries and rivers.

BIM says over 95% of all salmon farmed in Ireland are certified organic. Organically grown salmon are only fed a diet of sustainable organic feed. They are also raised in more spacious pens than traditional farmed salmon. The need to site locations for fish farms further out to sea, using more robust cages for weather, has been recognised by regulatory agencies. There is a move towards land-based aquaculture in Norway to reduce impact on local ecosystems. The industry says that antibiotic use is declining, and it says that "safe and effective vaccinations have since been developed for farmed fish and are now widely used". Many countries are now adopting a more sustainable approach to removing sea lice from salmon, using feeder fish such as wrasse and lumpsucker fish. Ireland's first lumpsucker hatchery was opened in 2015.

Ireland's first lumpsucker hatchery was opened in 2015.

Yes, as it is considered to have better potential for controlling environmental impacts, but it is expensive. As of October 2020, the department was handling over 20 land-based aquaculture applications.

The Irish Farmers' Association has represented fish and shellfish farmers for many years, with its chief executive Richie Flynn, who died in 2018, tirelessly championing the sector. His successor, Teresa Morrissey, is an equally forceful advocate, having worked previously in the Marine Institute in providing regulatory advice on fish health matters, scientific research on emerging aquatic diseases and management of the National Reference Laboratory for crustacean diseases.

BIM provides training in the national vocational certificate in aquaculture at its National Fisheries College, Castletownbere, Co Cork. It also trains divers to work in the industry. The Institute of Technology Carlow has also developed a higher diploma in aqua business at its campus in Wexford, in collaboration with BIM and IFA Aquaculture, the representative association for fish and shellfish farming.
