Northern Ireland was home to the world's first commercially viable tidal stream generator. [5] Trials were begun in Scotland then in England, before Marine Current Turbines installed the thousand-tonne [6] SeaGen turbine at the mouth of Strangford Lough. The lough was chosen because it has one of the fastest tidal flows in the world. The installation went live and was connected to the grid in mid-December, 2008, injecting an extra 1.2 megawatts of electricity. [7]
The turbine is scheduled to produce power for five years, though Marine Current Turbines were reported to have asked for an extension beyond their 2013 contract. [8] By March 2010, the turbine had passed an operating time of over 1,000 hours - a first for any marine energy device. [8]
Impact to the environment was closely scrutinised. [6] The device, built in Belfast's famous Harland and Wolff shipyard, is rigged with a sonar device which stops the motion of the rotor blades when it detects marine lifeform near it. While there has been no negative affect to the environment - a special protected wildlife area - it has been noticed that porpoises stop communicating while passing the device. [8]
Ireland is an island in Northern Europe in the north Atlantic Ocean. The island, of up to around 480 km (300 mi) north-south, and 275 km (171 mi) east-west, lies near the western edge of the European continental shelf, part of the Eurasian Plate. Its main geographical features include low central plains surrounded by coastal mountains. The highest peak is Carrauntoohil, which is 1,039 metres (3,409 ft) above sea level. The western coastline is rugged, with many islands, peninsulas, headlands and bays, while the southern and northern coasts feature a smaller number of substantial sea inlets, such as Lough Foyle and Cork Harbour; no part of the land is more than around 110 km (68 mi) from the sea. It was administratively divided into 32 counties, gathered in 4 provinces, though current arrangements, especially in Northern Ireland, differ from this model. The island is almost bisected by the River Shannon, which at 360.5 km (224 mi) with a 102.1 km (63 mi) estuary is the longest river in Ireland and flows south from County Cavan in the province of Ulster to form the boundary between Connacht and Leinster, and later Munster, and meet the Atlantic just south and west of Limerick. There are a number of sizeable lakes along Ireland's rivers, of which Lough Neagh is the largest.
Strangford Lough is a large sea lough or inlet in County Down, in the east of Northern Ireland. It is the largest inlet in Ireland and the wider British Isles, covering 150 km2 (58 sq mi). The lough is almost fully enclosed by the Ards Peninsula and is linked to the Irish Sea by a long narrow channel at its southeastern edge. The main body of the lough has at least seventy islands along with many islets (pladdies), bays, coves, headlands and mudflats. It is part of the Strangford and Lecale Area of Outstanding Natural Beauty. Strangford Lough was designated as Northern Ireland's first Marine Conservation Zone in 2013, and has been designated a Special Area of Conservation for its important wildlife.
Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods.
Portaferry is a small town in County Down, Northern Ireland, at the southern end of the Ards Peninsula, near the Narrows at the entrance to Strangford Lough. It is home to the Exploris aquarium and is well known for the annual Gala Week Float Parade. It hosts its own small Marina, the Portaferry Marina. The Portaferry – Strangford Ferry service operates daily at 30-minute intervals between the villages of Portaferry and Strangford, less than 1500 metres apart, conveying about 500,000 passengers per annum. It had a population of 2,514 people in the 2011 Census. The town is located within the Barony of Ards Upper.
The United Kingdom is the best location for wind power in Europe and one of the best in the world. The combination of long coastline, shallow water and strong winds make offshore wind unusually effective.
The production of renewable energy in Scotland is a topic that came to the fore in technical, economic, and political terms during the opening years of the 21st century. The natural resource base for renewable energy is high by European, and even global standards, with the most important potential sources being wind, wave, and tide. Renewables generate almost all of Scotland's electricity, mostly from the country's wind power.
Renewable energy in the United Kingdom contributes to production for electricity, heat, and transport.
The European Marine Energy Centre (EMEC) Ltd. is a UKAS accredited test and research centre focused on wave and tidal power development, based in the Orkney Islands, UK. The centre provides developers with the opportunity to test full-scale grid-connected prototype devices in wave and tidal conditions.
SeaGen was the world's first large scale commercial tidal stream generator. It was four times more powerful than any other tidal stream generator in the world at the time of installation. It was decommissioned by SIMEC Atlantis Energy Limited in summer 2019, having exported 11.6 GWh to the grid since 2008.
Marine Current Turbines Ltd (MCT), was a United Kingdom-based company that developed tidal stream generators, most notably the 1.2 MW SeaGen turbine. The company was bought by the German automation company, Siemens in 2012, who later sold the company to Atlantis Resources in 2015.
New Zealand has large ocean energy resources but does not yet generate any power from them. TVNZ reported in 2007 that over 20 wave and tidal power projects are currently under development. However, not a lot of public information is available about these projects. The Aotearoa Wave and Tidal Energy Association was established in 2006 to "promote the uptake of marine energy in New Zealand". According to their 10 February 2008 newsletter, they have 59 members. However, the association doesn't list its members.
Evopod is a unique tidal energy device being developed by a UK-based company Oceanflow Energy Ltd for generating electricity from tidal streams and ocean currents. It can operate in exposed deep water sites where severe wind and waves also make up the environment.
The Oyster was a hydro-electric wave energy device that used the motion of ocean waves to generate electricity. It was made up of a Power Connector Frame (PCF), which is bolted to the seabed, and a Power Capture Unit (PCU). The PCU is a hinged buoyant flap that moves back and forth with movement of the waves. The movement of the flap drives two hydraulic pistons that feed high-pressured water to an onshore hydro-electric turbine, which drives a generator to make electricity. Oyster was stationed at the European Marine Energy Centre (EMEC) at its Billia Croo site in Orkney, Scotland until the company ceased trading in 2015.
Marine energy or marine power refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world's oceans creates a vast store of kinetic energy, or energy in motion. Some of this energy can be harnessed to generate electricity to power homes, transport and industries.
A tidal farm is a group of tidal stream generators used for production of electric power. The potential of tidal farms is limited by the number of suitable sites across the globe as there are niche requirements to make a tidal farm cost effective and environmentally conscious.
A tidal stream generator, often referred to as a tidal energy converter (TEC), is a machine that extracts energy from moving masses of water, in particular tides, although the term is often used in reference to machines designed to extract energy from the run of a river or tidal estuarine sites. Certain types of these machines function very much like underwater wind turbines and are thus often referred to as tidal turbines. They were first conceived in the 1970s during the oil crisis.
The Saltire Prize, named after the flag of Scotland, was a national award for advances in the commercial development of marine energy.
SAE is a renewable energy company. It is incorporated in Singapore, but its operational headquarters are in Edinburgh, Scotland, United Kingdom. Initially, it was a developer of the tidal power turbines and projects, but after becoming a part of GFG Alliance it has expanded its business also to the waste-to-energy and hydropower.
Many tidal stream generators have been developed over the years to harness the power of tidal currents flowing around coastlines. These are also called tidal stream turbines (TST), tidal energy converters (TEC), or marine hydro-kinetic (MHK) generation. These turbines operate on a similar principle to wind turbines, but are designed to work in a fluid approximately 800 times more dense than air which is moving at a slower velocity. Note that tidal barrages or lagoons operate on a different principle, generating power by impounding the rising and falling tide.
Minesto AB is a Swedish developer of electricity producing tidal kite turbines, based in Gothenburg. They also have a manufacturing base in Holyhead, North Wales, and a test facility at Portaferry, Northern Ireland.
