A Connemara company has secured €3 million from the European Commission to research and design a marine turbine that uses recycled materials for the first time.

As The Times Ireland edition reports, designers at ÉireComposites in Indreabhán, Co Galway, believe their marine hydrokinetic power system can produce clean energy reliably at a reduced cost.

It will work with partners including marine renewable energy specialists Ocean Renewable Power Company (ORPC), NUI Galway, Mitsubishi Chemical Advanced Materials in Germany and Consiglio Nazionale delle Ricerche, the Italian state research company.

He says that marine turbine systems can harvest a potential 615 terawatt-hours per year from tidal streams, ocean currents and river currents – as in approximately 21 times Ireland’s annual electricity use.

Named “Crimson”, as in “Commercialisation of a Recyclable and Innovative Manufacturing Solution for an Optimised Novel”, the turbine project is being supported by the European Commission’s Horizon 2020 Fast Track to Innovation programme.

ÉireComposites has already worked with ORPC, which has headquarters in Portland, Maine, USA and a base in Ireland, on previous turbine design projects.

These include ORPC’s first commercial river generation power system, installed in Igiugig, Alaska, to provide a remote community with local energy from the Kvichak river.

The Connemara company is one of 16 partners in seven countries in the EU-funded Marewind project to design the next generation of offshore wind turbines.

It also recently secured a contract to design and manufacture equipment for the European Space Agency’s Altius satellite, which is due to be launched from French Guiana in 2023

Energy Minister Eamon Ryan announced today that Irish company Wavebob Ltd has secured a grant of $2.4 million (€1.83 million) from the US Department of Energy to prepare for a commercial-scale wave energy demonstration project planned for US waters in 2013.

Minister Ryan also announced that Bord Gáis is to invest €1.8m in Wavebob Ltd, bringing the total investments to €3.6 million .

The Minister said, "The Irish Government is committed to the development and commercialisation of ocean energy. Wavebob is an innovative Irish company that is thriving even in this tough economic climate, securing one investment after another from major energy utilities at home and abroad.

The recognition of Wavebob's potential by the US Department of Energy also goes to show that as the effects of climate change become increasingly evident, the exploitation of new, clean energy sources is becoming more and more urgent. The Irish Government will continue our absolute commitment to the emergent ocean energy sector and to encouraging the work of world-class companies such as Wavebob.

Renewable energy is the way forward for Ireland. We can use our own homegrown energy and create the new Irish jobs. I wish Wavebob well in their venture"

The grant forms part of $37m in marine and hydrokinetic energy grants announced by the US Department. It will be used to further develop Wavebob Ltd.'s wave energy converter (WEC), which is currently in pre-commercial development. At full scale, the device is capable of producing in excess of one megawatt of energy with average output of over 500kW at sites in the North Atlantic and Pacific oceans.

The 'Wavebob' was one of the first WEC's in the world to successfully produce electricity from ocean swell in 2007. The US Department of Energy grant will be used specifically to develop and test their advanced power take-off device. The project benefits from support and collaboration with Vattenfall, one of Europe's largest utility companies, and Chevron and Lockheed Martin in the US.

"The Department of Energy's funding program for marine hydrokinetic technologies is vital to the development of both products and markets, at home and abroad. We are honoured to be selected for this award through a highly competitive process, and to be working with a distinguished team of leaders in maritime technology", said Derek Robertson, President of Wavebob's US operations based in Annapolis, Maryland.

Traditional sources of finance for technology development have become more and more scarce as a result of the global economic crisis, with the result that many Irish companies are struggling to survive. On the bright side however, Andrew Parish, C.E.O. of Wavebob Ltd., feels that the Irish energy utilities are making particularly good use of state assets in recognizing the world-class potential of a small Irish indigenous company such as Wavebob Ltd. "This investment from Bord Gáis builds on a previous technical agreement with ESBI and clearly demonstrates that Irish utilities recognize the ocean energy opportunity and are key agents of Government policy in maximizing the potential to Ireland of this immense natural resource", he said.

John Mullins, CEO of Bord Gais, says that Ireland has one of the best wave resources off its west coast, "It is important that utilities such as Bord Gais foster the development of companies like Wavebob, to enable them to advance their technology. Bord Gais will be actively involved in this development and we will commit our own resources to its advancement", " he said.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
