In south Wales's Pembrokeshire region, a £60 million marine energy project that will help tackle climate change while reviving the local economy in the wake of Covid-19 has been given the green light.

The UK Government and Welsh Government have now approved the business case for the Pembroke Dock Marine project, which is expected to generate £73.5 million a year to the Swansea Bay City Region’s economy.

Pembroke Dock Marine is led by the private sector, with support from Pembrokeshire County Council. The project is expected to generate more than 1,800 jobs in the next 15 years.

The project is made up of four elements:

• The Marine Energy Test Area within the Milford Haven Waterway led by Marine Energy Wales, enabling technology developers to test their marine energy devices close to their base of operation
• The largest facility of its kind in the world, a 90 square kilometre Pembrokeshire Demonstration Zone delivered by Wave Hub Limited that will enable the deployment of future energy generating technologies, including floating wind
• Marine Energy Engineering Centre of Excellence - a technology, innovation and research centre delivered by the Offshore Renewable Energy (ORE) Catapult
• Redevelopment of land at Pembroke Dock, led by the Port of Milford Haven (see latest), to deliver the infrastructure needed by the industry as it continues to mature

#GalwayBay - In a major boost for the marine energy sector, the Government has approved a 35-year foreshore lease for an upgraded test site in Galway Bay off Spiddal.

Galway Bay FM reports on yesterday’s (Tuesday 19 December) announcement that paves the way for a quarter-scale renewable energy testing facility for wind and wave devices to be established on the site, which has been used to test new technology since 2006 and which is expected to further the aims of the Harnessing Our Ocean Wealth Strategy.

In a nod to local concerns over the project — which received more than 500 submissions in a public consultation last year — the site will be restricted to hosting a single floating wind energy device at ant given time, among other conditions.

#GalwayBay - More than 500 submissions were lodged during last year’s public consultation on proposals to upgrade the marine energy test site in Galway Bay off Spiddal.

And according to the Connacht Tribune, many voiced serious concerns over the project’s potential impact on Galway Bay.

As previously reported on Afloat.ie, the Marine Institute had applied to the Department of the Environment, Community and Local Government for a foreshore lease for the site where prototype marine and renewable energy technology would be tested at reduced scale.

The consultation period, which closed on 17 June last, was accompanied by a public information evening on the project and its ambitions.

However, the Connacht Tribune reports that the response from local businesses and communities has been largely negative.

One fisherman expressed his fear that the lease area could be expanded into prawn grounds already reduced by the original lease for the site a decade ago.

Other concerns include the 35-year period of the lease, the scope and veracity of information provided, and the lack of an Environmental Impact Statement, as well as the impact on tourism on the Wild Atlantic Way in South Connemara.

#PowerFromTheSea - Ireland could be central to the mainstreaming of ocean energy over the next 35 years, according to a new report from the emerging industry.

As The Irish Times reports, the Marine Renewables Industry Association (MRIA) maintains a healthy outlook for the development of wave and tidal energy projects despite revising its predictions for the next decade.

Though "technical challenges" remain in offshore renewables for both wave and wind power generation, Ireland has been marked for "generally strong" policy in the area – and has been encouraged to work with Scotland towards closing the funding gap between research and commercial application.

That view chimes with news from the Maritime Journal, which says Ireland's marine energy market could be worth €15 billion by 2050.

Singled out for its significant contributions in the sector is the SFI Research Centre, Marine Renewable Energy Ireland (MaREI) at University College Cork (UCC), which also houses the Lir National Ocean Test Facility.

That's one of a number of Irish 'innovation hubs' involved in exploring the potential benefits of ocean energy, as previously reported on Afloat.ie – and as discussed at the recent symposium of marine energy leaders in Cork.

#MarineWildlife - If you've ever wanted to get closer to Ireland's marine wildlife, a new series of weekend excursions in West Cork may be just the ticket.

The Southern Star reports on the 'Discover Wildlife Weekends' being run from Rosscarbery by local company Ireland's Wildlife starting this April, where those taking part will be led by expert guides to explore the coastal region and have the best opportunities to spot the many species of whales and dolphins that visit our shores.

Weather permitting, the weekends will also involve some offshore whale watching in the company of 'whale watch supremo' Colin Barnes and the Irish Whale and Dolphin Group's (IWDG) sightings co-ordinator Pádraig Whooley.

And birdwatching will also be a feature, as West Cork is a hotspot for our feathered friends - from merlins and peregrine falcons to coastal waders and more exotic fowl that skirt our coasts on their spring migrations.

Meanwhile, marine sector stakeholders have expressed their concerns over the designation of six new offshore marine areas by the National Parks and Wildlife Service.

As previously reported on Afloat.ie, the six sites at Blackwater Bank in Wexford, the West Connacht coast, Hempton's Turbot Bank in Donegal, the Porcupine Bank Canyon off Kerry, the South-East Rockall Bank, and the stretch from Rockabill to Dalkey Island off Dublin have been proposed for designation as Special Areas of Conservation (SACs) to protect marine habitats and species listed on the 1992 EU Habitats Directive.

But at a recent meeting at the Irish Farm Centre in Dublin, a coalition of fish farmers, fishermen and marine energy stakeholders have hit out at what they characterise as "the appalling handling of inshore designations since the 1990s by the State", which they claim "has resulted in hundreds of job losses and a flight of serious investment" from Ireland's coastal areas.

“Our experience of the Irish Government’s application of the EU Habitats Directive has been a saga of mismanagement, foot dragging and buck-passing which has left over 500 fish farming licences in limbo for over 10 years and a backlog of red tape and bureaucracy which could see producers waiting until 2020 and beyond for simple renewals which are vital to underpin their businesses," said IFA aquaculture executive Richie Flynn.

"These new offshore SACs will have the same effect of preventing any fishing, marine energy or aquaculture being carried out in these areas if left in the hands of the same agencies to manage."

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.
