Minister for Environment Eamon Ryan has rejected claims that he is impeding development of floating offshore wind and criticised “false promises” made by politicians

As The Irish Independent reports, Ryan was responding to comments by Fianna Fáil senator Lisa Chambers where she claimed he and his party were “getting green wrong”.

Senator Chambers, who is a European election candidate, had accused him and his party of ignoring the wind potential off the coast of her western constituency and refusing to develop floating turbines.

Ryan, who published the Future Framework for offshore wind earlier this week, said that floating wind farm technology was not sufficiently developed to cope with conditions in Irish waters.

“I would love to see floating offshore wind deployable today because that’s really our big opportunity,” he said.

“But I’m sorry I have to inform some of our colleagues in government that it’s not technically available or viable today,” he said.

Pointing out that floating wind off Scotland operates in wave heights of 10 metres, Ryan said that Ireland had 18-metre wave height and limited safe shipping days off the west coast.

“We need the technology to evolve further,"he said, and this is what industry major players were saying.

Oceanographers at Bangor University in Wales are calling for research into the environmental impact of turbulence caused by tidal flow past floating deep-water wind farms.

New research is needed to fully understand how locating varying types of wind turbines could affect not only the seabed, but the waters, and everything they contain, according to Dr Ben Lincoln of Bangor University.

Britain leads offshore wind energy production globally, with current power generation meeting one-third of the national demand (~10GW), and floating wind in deep shelf sea areas has been identified as a major route in the “net zero” goal.

A current target to produce 50GW by 2030 is an increase of 67% on the target set just 12 months ago.

However, Dr Lincoln and fellow researchers notes that offshore sites at a depth of over 50 metres are very different in nature to shallow coastal sites used so far.

They say that with an additional 20,000 wind turbines set to be built in British water, there is a need to ensure full awareness of the positive and negative effects their presence could have on the surrounding environment.

“Our shelf seas are fully mixed during winter, but during summer months the deeper regions stratify, with a warm surface layer overlying the cooler water below,”Dr Lincoln has said in a statement.

“ This triggers a phytoplankton bloom which can be seen from space and forms the base of the marine food chain, supporting fish, seabirds and whales,”he explains.

“ During summer months following the spring bloom, phytoplankton growth is supported by nutrients stirred up from below by turbulence associated with wind and tides. This turbulence also mixes oxygen down to the deep water, where it is required for other key biological processes,”he notes.

“Environmental assessments for the shallow shelf seas have focused on wildlife using or living within the affected areas. The difference with the deeper seas is that the fundamental functioning of the seas themselves could be affected,” Lincoln says.

“Turbulent mixing determines the timing and rate of the food supply on which marine ecosystem and key species rely. Flow past deep water wind farms will introduce ‘anthropogenic’ or man-made turbulence, and increase mixing,”he says.

“ This fundamental change could lead to significant regional impacts, which must be assessed. However, impacts are not necessarily negative, with the potential to enhance productivity and offset the impact of increasing stratification due to climate change,”he says.

“There’s no doubt that this growth in renewable energy is essential to meet global 2050 net zero commitments,” he says.

More details are in a research paper: Anthropogenic Mixing in Seasonally Stratified Shelf Seas by Offshore Wind Farm Infrastructure, published in Frontiers.

RTÉ News reports that the ESB has put before planners its proposal for an offshore wind turbine production base at its Moneypoint plant.

The pre-consultation on the planned facility, envisaged as part of the ESB’s multi-billion-euro Green Atlantic @ Moneypoint programme, will continue till June but formal plans are not expected to go before An Board Pleanála until 2024.

“Moneypoint will become a centre for the construction and deployment of floating wind,” a spokesperson said of the proposed facility, part of the ESB’s plans to evolve the West Clare station from coal power into a green energy hub.

The State-owned power company outlined benefits of the site such as its existing deepwater access, and its potential to “a significant number of direct jobs in the Mid-West region”.

Elsewhere, a Dutch offshore energy firm is proposing a £1 billion investment off Northern Ireland that could generate power for up to half a million homes.

As the Belfast Telegraph reports, SBM Offshore says it is investigation two sites in the North Channel for a series of “new generation floating wind turbines”.

“The two sites would generate a combined 400MW, representing 13% of Northern Ireland’s energy needs and up to 57% of domestic requirement,” project director Niamh Kenny said.

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.
