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.

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."

Marine Protected Areas (MPAs) - FAQS

Marine protected areas (MPAs) are geographically defined maritime areas where human activities are managed to protect important natural or cultural resources. In addition to conserving marine species and habitats, MPAs can support maritime economic activity and reduce the effects of climate change and ocean acidification.

MPAs can be found across a range of marine habitats, from the open ocean to coastal areas, intertidal zones, bays and estuaries. Marine protected areas are defined areas where human activities are managed to protect important natural or cultural resources.

The world's first MPA is said to have been the Fort Jefferson National Monument in Florida, North America, which covered 18,850 hectares of sea and 35 hectares of coastal land. This location was designated in 1935, but the main drive for MPAs came much later. The current global movement can be traced to the first World Congress on National Parks in 1962, and initiation in 1976 of a process to deliver exclusive rights to sovereign states over waters up to 200 nautical miles out then began to provide new focus

The Rio ‘Earth Summit’ on climate change in 1992 saw a global MPA area target of 10% by the 2010 deadline. When this was not met, an “Aichi target 11” was set requiring 10% coverage by 2020. There has been repeated efforts since then to tighten up MPA requirements.

Marae Moana is a multiple-use marine protected area created on July 13th 2017 by the government of the Cook islands in the south Pacific, north- east of New Zealand. The area extends across over 1.9 million square kilometres. However, In September 2019, Jacqueline Evans, a prominent marine biologist and Goldman environmental award winner who was openly critical of the government's plans for seabed mining, was replaced as director of the park by the Cook Islands prime minister’s office. The move attracted local media criticism, as Evans was responsible for developing the Marae Moana policy and the Marae Moana Act, She had worked on raising funding for the park, expanding policy and regulations and developing a plan that designates permitted areas for industrial activities.

Criteria for identifying and selecting MPAs depends on the overall objective or direction of the programme identified by the coastal state. For example, if the objective is to safeguard ecological habitats, the criteria will emphasise habitat diversity and the unique nature of the particular area.

Permanence of MPAs can vary internationally. Some are established under legislative action or under a different regulatory mechanism to exist permanently into the future. Others are intended to last only a few months or years.

Yes, Ireland has MPA cover in about 2.13 per cent of our waters. Although much of Ireland’s marine environment is regarded as in “generally good condition”, according to an expert group report for Government published in January 2021, it says that biodiversity loss and ecosystem degradation are of “wide concern due to increasing pressures such as overexploitation, habitat loss, pollution, and climate change”.

The Government has set a target of 30 per cent MPA coverage by 2030, and moves are already being made in that direction. However, environmentalists are dubious, pointing out that a previous target of ten per cent by 2020 was not met.

Conservation and sustainable management of the marine environment has been mandated by a number of international agreements and legal obligations, as an expert group report to government has pointed out. There are specific requirements for area-based protection in the EU Marine Strategy Framework Directive (MSFD), the OSPAR Convention, the UN Convention on Biological Diversity and the UN Sustainable Development Goals. 

Yes, the Marine Strategy Framework directive (2008/56/EC) required member states to put measures in place to achieve or maintain good environmental status in their waters by 2020. Under the directive a coherent and representative network of MPAs had to be created by 2016.

Ireland was about halfway up the EU table in designating protected areas under existing habitats and bird directives in a comparison published by the European Commission in 2009. However, the Fair Seas campaign, an environmental coalition formed in 2022, points out that Ireland is “lagging behind “ even our closest neighbours, such as Scotland which has 37 per cent. The Fair Seas campaign wants at least 10 per cent of Irish waters to be designated as “fully protected” by 2025, and “at least” 30 per cent by 2030.

Nearly a quarter of Britain’s territorial waters are covered by MPAs, set up to protect vital ecosystems and species. However, a conservation NGO, Oceana, said that analysis of fishing vessel tracking data published in The Guardian in October 2020 found that more than 97% of British MPAs created to safeguard ocean habitats, are being dredged and bottom trawled. 

There’s the rub. Currently, there is no definition of an MPA in Irish law, and environment protections under the Wildlife Acts only apply to the foreshore.

Current protection in marine areas beyond 12 nautical miles is limited to measures taken under the EU Birds and Habitats Directives or the OSPAR Convention. This means that habitats and species that are not listed in the EU Directives, but which may be locally, nationally or internationally important, cannot currently be afforded the necessary protection

Yes. In late March 2022, Minister for Housing Darragh O’Brien said that the Government had begun developing “stand-alone legislation” to enable identification, designation and management of MPAs to meet Ireland’s national and international commitments.

Yes. Environmental groups are not happy, as they have pointed out that legislation on marine planning took precedence over legislation on MPAs, due to the push to develop offshore renewable energy.

No, but some activities may be banned or restricted. Extraction is the main activity affected as in oil and gas activities; mining; dumping; and bottom trawling

The Government’s expert group report noted that MPA designations are likely to have the greatest influence on the “capture fisheries, marine tourism and aquaculture sectors”. It said research suggests that the net impacts on fisheries could ultimately be either positive or negative and will depend on the type of fishery involved and a wide array of other factors.

The same report noted that marine tourism and recreation sector can substantially benefit from MPA designation. However, it said that the “magnitude of the benefits” will depend to a large extent on the location of the MPA sites within the network and the management measures put in place.
