In 2004, seawater was reintroduced in the hope of flushing out contamination inflows from the tidal barrage were envisaged as a complementary permanent solution. In January 2003, PFOS had been found at 730 ng/L in Lake Shihwa water. Concentrations of perfluorooctane sulfonate (PFOS) measured in Lake Sihwa were among the greatest ever measured in the environment. : 37 Environmental context Īfter the seawall was built in 1994, pollution built up in the newly created Sihwa Lake reservoir, making its water useless for agriculture. The project cost of US$560 million was borne by the South Korean Government. The power station was built in 2011 and started to operate in 2012. The working basin area was originally intended to be 43 km 2 (17 sq mi) and has been reduced by land reclamation and freshwater dykes to 30 km 2 (12 sq mi), likely to be reduced further. The station's mean operating tidal range is 5.6 m (18 ft), with a spring tidal range of 7.8 m (26 ft). This slightly unconventional and relatively inefficient approach has been chosen to balance a complex mix of existing land use, water use, conservation, environmental and power generation considerations. Ten 25.4 MW submerged bulb turbines are driven in an unpumped flood generation scheme power is generated on tidal inflows only, and the outflow is sluiced away, i.e. The tidal barrage makes use of a seawall constructed in 1994 for flood mitigation and agricultural purposes. It is operated by the Korea Water Resources Corporation. When completed in 2011, it surpassed the 240 MW Rance Tidal Power Station, which was the world's largest for 45 years. Sihwa Lake Tidal Power Station is the world's largest tidal power installation, with a total power output capacity of 254 MW. As shown below 9, tidal fences are connected to electrical generators, allowing for energy to be converted into electricity.Location of Sihwa Lake Tidal Power Station in South Koreaģ7☁8′47″N 126☃6′46″E / 37.31306°N 126.61278☎ / 37.31306 126.61278 These fences are often grouped together in order to provide large amounts of power to generators in a condensed area. These are connected with a single structure called a “fence”. Tidal turbines act as a single unit with multiple turbines along the vertical structure. Tidal fences are a hybrid between tidal barrages and tidal turbines. Tidal turbines are individual turbines that are often placed closely to each other to produce large amounts of energy. This turbine is connected to an electrical generator, allowing for electricity to be stored. A tidal turbine utilizes the tides under water to push against a generator, forcing it to move. Tidal turbines are very similar to wind turbines, however they are located under water. This process allows for energy to be harnessed consistently with the movement of the tides. 8 The force that this water flows with then turns a turbine or forces air pressure through a pipe that in turn, moves the turbine. This method uses a large dam structure, known as a barrage, that forces the tide to flow in and out of tunnels within the dam structure. As the following video 7 explains, Tidal Energy is created through a variety of ways.Īs discussed in the video, tidal barrages are the main source of converting the tidal power into useable energy in the form of electricity. Tidal Energy converts the natural rising and falling patterns of ocean tides into electricity. ![]()
