Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods.
The Voith Group is a German multinational technology company with a broad portfolio of systems, products, services and digital applications. Voith works in the markets of energy, paper, raw materials and transport & automotive. Founded in 1867, the company today has around 21,000 employees, sales of €4.9 billion and locations in over 60 countries worldwide and is thus one of the larger family-owned companies in Europe.
The Pelamis Wave Energy Converter was a technology that used the motion of ocean surface waves to create electricity. The machine was made up of connected sections which flex and bend as waves pass; it is this motion which is used to generate electricity.
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.
The European Marine Energy Centre (EMEC) Ltd is a UKAS accredited test and research center 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.
Islay LIMPET was the world's first commercial wave power device and was connected to the United Kingdom's National Grid.
SeWave is a wave farm project in Nípanin, Faroe Islands. The project is developed by the joint venture of the Scottish wave energy developer Wavegen and the Faroe's power company SEV.
Pelamis Wave Power designed and manufactured the Pelamis Wave Energy Converter – a technology that uses the motion of ocean surface waves to create electricity. The company was established in 1998 and had offices and fabrication facilities in Leith Docks, Edinburgh, Scotland. It went into administration in November 2014.
The Oyster is a hydro-electric wave energy device that uses the motion of ocean waves to generate electricity. It is 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.
Aquamarine Power was a wave energy company, founded in 2005 to commercialise the Oyster wave energy converter, a device to capture energy from near-shore waves. The company's head offices were in Edinburgh, Scotland. The company ceased to trade on 20 November 2015.
Trevor Whittaker FREng is Professor of coastal engineering at Queen's University, Belfast having been awarded a personal chair in 1993. He was elected a Fellow of The Royal Academy of Engineering in 2002. He is specialist adviser to the board of Aquamarine Power, a company formed to commercially develop the Oyster wave energy converter.
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 run of 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.
Kikagati Hydroelectric Power Station, also referred to as Kikagati Power Station, is a 15.57 MW (20,880 hp) hydroelectric power station, in Uganda.
The Mutriku Breakwater Wave Plant is a wave power plant constructed by Ente Vasco de la Energía (EVE), the Basque energy agency, in the bay of Mutriku in the Bay of Biscay. It is the world's first breakwater wave power plant with a multiple turbine arrangement. The plant has a capacity of 296 kW from 16 turbo generator sets. It was inaugurated on July 8, 2011.
Events from the year 2000 in Scotland.
Oscillating water columns (OWCs) are a type of wave energy converter that harness energy from the oscillation of the seawater inside a chamber or hollow caused by the action of waves. OWCs have shown promise as a renewable energy source with low environmental impact. Because of this, multiple companies have been working to design increasingly efficient OWC models. OWC are devices with a semi-submerged chamber or hollow open to the sea below, keeping a trapped air pocket above a water column. Waves force the column to act like a piston, moving up and down, forcing the air out of the chamber and back into it. This continuous movement forces a bidirectional stream of high-velocity air, which is channeled through a power take-off (PTO). The PTO system converts the airflow into energy. In models that convert airflow to electricity, the PTO system consists of a bidirectional turbine. This means that the turbine always spins the same direction regardless of the direction of airflow, allowing for energy to be continuously generated. Both the collecting chamber and PTO systems will be explained further under "Basic OWC Components."
The Nangbeto Dam is an embankment dam on the Mono River in the Plateaux Region of Togo. It was constructed between 1984 and 1987 for the purpose of providing hydroelectric power to both Togo and Benin as well as creating fisheries and supplying water for irrigation. The dam's 65.6 megawatts (88,000 hp) power station was commissioned in June 1987. The project was financed by the World Bank and African Development Bank at a cost of US$98.22 million.
