Sotenäs Wave Power Station
Sotenäs is a wave farm located in Kungshamn, in the municipality of Sotenäs, Sweden. The facility consists of 36 wave energy converters (WECs), with a total installed capacity of nearly 3 MW. Each WEC generates power using point absorber buoys connected to linear generators on the seabed. The generators are located at a depth of . According to Seabased, the technology used in the project could deliver electricity for under 10 cents per kWh. Initial announcements stated that the power plant would eventually expand to around 10 MW capacity, but in 2017 Seabased announced it would no longer expand the plant beyond the 36 WECs already in place. History * In February 2010, the Swedish Energy Agency awarded an investment grant to Fortum and Seabased for the wave power station. *9 December 2011, Fortum and Seabased sign an agreement to jointly construct a wave power station in Sotenäs, Sweden. Seabased agreed to manufacture buoys, generators, substations and converters at a fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It borders Norway to the west and north, and Finland to the east. At , Sweden is the largest Nordic country and the List of European countries by area, fifth-largest country in Europe. The Capital city, capital and largest city is Stockholm. Sweden has a population of 10.5 million, and a low population density of ; around 87% of Swedes reside in urban areas in the central and southern half of the country. Sweden’s urban areas together cover 1.5% of its land area. Because the country is so long, ranging from 55th parallel north, 55°N to 69th parallel north, 69°N, the climate of Sweden is diverse.

Fortum
Fortum Oyj is a Finnish state-owned energy company located in Espoo, Finland. In addition to Finland, it focuses on Germany and other countries in Central Europe, Great Britain, Russia and the Nordic region. Fortum operates power plants, including co-generation plants, and generates and sells electricity and heat. The company also sells waste services such as recycling, reutilisation, final disposal solutions and soil remediation and environmental constructions services, and other energy-related services and products e.g. consultancy services for power plants and electric vehicle charging. Fortum is listed on the NASDAQ OMX Helsinki stock exchange. In 2020 Fortum was the biggest company in Finland by its revenue. The majority of its income came from Uniper that became Fortum's subsidiary in March 2020. Uniper was nationalised by Germany on the for 8 billion euros. Fortum is Europe's third-largest producer of carbon-free electricity, Europe's second-largest producer of nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skagerrak
The Skagerrak (, , ) is a strait running between the Jutland peninsula of Denmark, the southeast coast of Norway and the west coast of Sweden, connecting the North Sea and the Kattegat sea area through the Danish Straits to the Baltic Sea. The Skagerrak contains some of the busiest shipping routes in the world, with vessels from every corner of the globe. It also supports an intensive fishing industry. The ecosystem is strained and negatively affected by direct human activities. Oslo and Gothenburg are the only large cities in the Skagerrak region. Name The meaning of ''Skagerrak'' is most likely the Skagen Channel/Strait. Skagen is a town near the northern cape of Denmark (The Skaw). ''Rak'' means 'straight waterway' (compare the Damrak in Amsterdam); it is cognate with ''Reach (geography), reach''.Nudansk Ordbog (1993), 15th edition, 2nd reprint, Copenhagen: Politikens Forlag, entry ''Skagerrak''.

Kilowatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical c ...

Wave Farm
Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC). Waves are generated by wind passing over the sea's surface. As long as the waves propagate slower than the wind speed just above, energy is transferred from the wind to the waves. Air pressure differences between the windward and leeward sides of a wave crest and surface friction from the wind cause shear stress and wave growth. Wave power is distinct from tidal power, which captures the energy of the current caused by the gravitational pull of the Sun and Moon. Other forces can create currents, including breaking waves, wind, the Coriolis effect, cabbeling, and temperature and salinity differences. As of 2022, wave power is not widely employed for commercial applications, after a long series of trial projects. Attempts to use this energy began in 1890 o ...

Linear Alternator
A linear alternator is essentially a linear motor used as an electrical generator. An alternator is a type of alternating current (AC) electrical generator. The devices are often physically equivalent. The principal difference is in how they are used and which direction the energy flows. An alternator converts mechanical energy to electrical energy, whereas a motor converts electrical energy to mechanical energy. Like most electric motors and electric generators, the linear alternator works by the principle of electromagnetic induction. However, most alternators work with rotary motion, whereas ''linear'' alternators work with ''linear'' motion (i.e. motion in a straight line). Theory When a magnet moves in relation to an electromagnetic coil, this changes the magnetic flux passing through the coil, and thus induces the flow of an electric current, which can be used to do work. A linear alternator is most commonly used to convert back-and-forth motion directly into electrical e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tethys (database)
Tethys is an online knowledge management system that provides the marine renewable energy (MRE) and wind energy communities with access to information and scientific literature on the environmental effects of devices. Named after the Greek titaness of the sea, the goal of the Tethys database is to promote environmental stewardship and the advancement of the wind and marine renewable energy communities. The website has been developed by the Pacific Northwest National Laboratory (PNNL) in support of the U.S. Department of Energy (DOE) Wind and Water Power Technologies Office. Tethys hosts information and activities associated with two international collaborations known as OES-Environmental and WREN, formed to examine the environmental effects of marine renewable energy projects and wind energy projects, respectively. Content overview As industry, academia, and government seek to develop new renewable energy sources from moving water and wind, there exists an opportunity to gath ...
