Marine energy - Tidal power

1 The energy from moving masses of water — a popular form of

Hydroelectricity#Generating methods|hydroelectric power

generation. Tidal power generation comprises three main forms, namely:

tidal stream power, tidal barrage power, and dynamic tidal power.


Tidal power

1 'Tidal power', also called 'tidal energy', is a form of hydropower that

converts the energy of tides into useful forms of power - mainly

electricity.

1 new Tidal stream generator#Axial turbines|axial turbines, Tidal stream generator#Vertical and horizontal axis crossflow turbines|cross flow turbines), indicate that the total

availability of tidal power may be much higher than previously

assumed, and that economic and environmental costs may be brought

down to competitive levelshttps://store.theartofservice.com/the-tidal-power-toolkit.html

Tidal power - Generation of tidal energy

1 Tidal power is taken from the Earth's oceanic tides; tidal forces are

periodic variations in gravitational attraction exerted by celestial bodies



1 Tidal power is the only technology that draws on energy inherent in the orbital characteristics of the Earth–Moon system, and to a lesser extent

in the Earth–Sun system



1 While tidal power will take additional energy from the system, the effect is negligible and would only be noticed

over millions of years.


Renewable energy in Scotland - Tidal power

1 To date the only installed tidal power plant of any size is the 240MW rated

Rance tidal power plant|barrage scheme at the Rance Estuary in

Brittany, which has been operating successfully for more than 25 years, although there are a number of other

much smaller projects around the world.

Corporation and International Power, received a 25-year operational lease from the Crown Estate for a 400MW tidal power

Renewable energy in Pakistan - Tidal power

1 Tidal power has not yet been operational in Pakistan compared to

other renewable energy technologies, but in near future it

may play a key role. Some think that tidal power plants in coastal creeks

of Pakistan can serve the energy crisis conundrum up to some level.

1 Government has issued licence to private companies to take measures

to build tidal power stations in February 2013


Dynamic tidal power

1 'Dynamic tidal power' or 'DTP' is an untried but promising technology for tidal

power generation


Dynamic tidal power - Stable power

1 The generation of tidal power is highly predictable due to the

deterministic nature of tides, and independent of weather conditions or

climate change


Dynamic tidal power - High availability

1 Dynamic tidal power doesn't require a very high natural tidal range, but instead

an open coast where the tidal propagation is alongshore. Such tidal

conditions can be found in many places around the world, which means that the theoretical potential of DTP is very high. Along the Chinese coast for example, the

total amount of available power is estimated at 80 - 150 GW.


Dynamic tidal power - Status of technological development

1 Various mathematical and physical models have been conducted to model and predict the 'Hydraulic

head|head' or water level differential over a dynamic tidal power dam


Dynamic tidal power - Recent progress

1 In December 2011 the Dutch Ministry of Economy, Agriculture and Innovation (ELI)

awarded a grant funding subsidy to the POWER consortium, led by Strukton and managed by

ARCADIS. The maximum grant is about 930.000 euro, which is matched by a similar amount of co-financing from the consortium partners. The

POWER group conducts a detailed feasibility study on the development of Dynamic Tidal Power (DTP) in China in a 3-year programme jointly conducted with Chinese government

institutes.

Uldolmok Tidal Power Station

1 The South Korean government plans to increase this capacity of to by

the end of the year 2013, increasing the demand cover to 46,000

households, while simultaneously working on the Sihwa Lake Tidal Power Station. Part of the goal of

generating through tidal power by 2020.


List of tidal power stations

1 The following page lists most 'power stations that run on tidal

power'. Since tidal stream generators are an immature technology, no

technology has yet emerged as the clear standard. A large variety of designs are being experimented

with, with some very close to large scale deployment. Hence, the following page lists stations of

different technologies.https://store.theartofservice.com/the-tidal-power-toolkit.html

Sihwa Lake Tidal Power Plant

1 'Sihwa Lake Tidal Power Station' is the world's largest tidal power

installation, with a total power output capacity of 254 Megawatt|MW,

surpassing the 240 MW Rance Tidal Power Station after 45 years. It is

operated by the Korean Water Resource Corporation.

conservation, environmental and power generation

considerations.http://www.waterpowermagazine.com/story.asp?

1 In 2004, seawater was reintroduced in the hope of flushing out

contamination; inflows from the tidal barrage are envisaged as a complementary permanent

solution.http://www.eer.wustl.edu/McDonnellMayWorkshop/Presentation_files/Saturday/Saturday/Park.pdf Sihwa

Kislaya Guba Tidal Power Station

1 The 'Kislaya Guba tidal power station|Tidal Power Station' is an

experimental project in Kislaya Guba, Russia.


Kislaya Guba Tidal Power Station

1 The station is the world's 5th largest tidal power plant with the output

capacity of 1.7Megawatt|MW


Rance tidal power plant

1 Opened on 26 November 1966, it is currently operated by Électricité de France, and is the second largest tidal power station in the world, in

terms of installed capacity, since the Sihwa Lake Tidal Power Station

surpassed it after 45 years


Rance tidal power plant - History

1 An early attempt to build a tidal power plant was made at Aber

Wrac'h in the Finistère in 1925, but due to insufficient finance, it was abandoned in 1930. Plans for this

plant served as the draft for follow-on work. Use of tidal energy is not an entirely new concept, since Tide mill|tidal mills have long existed in areas exposed to tides, particularly along

the Rance River|Rance.https://store.theartofservice.com/the-tidal-power-toolkit.html

Rance tidal power plant - History

1 The idea of constructing a tidal power plant on the Rance dates to Gerard Boisnoer in

1921


Incheon Tidal Power Station

1 The station is expected to generate up to 2.41TWh of energy annually upon its completion in June 2017.

Ocean power in New Zealand - Tidal power

1 Tidal power is generated by capturing some of the energy in the tides as they cycle forth and back,

twice each day. Tidal devices can be weir or dam like structures (Barrage (dam)|barrages), used to hold the tide back, or turbines anchored

within the tidal stream.


EMEC - Tidal power

1 The tidal power test site at the Fall of Warness, to the west of the island of Eday, was chosen for its high velocity marine currents which reach almost 4m/s (7.8 knots) at spring tides. The

facility offers five test berths at depths ranging from 25m to 50m in

an area 2km across and approximately 4km in length.


Low carbon power - Tidal power

1 Tidal power is a form of hydropower that converts the energy of tides into

electricity or other useful forms of power. The first large-scale tidal

power plant (the Rance Tidal Power Station) started operation in 1966. Although not yet widely used, tidal

power has potential for future electricity generation. Tides are more

predictable than wind energy and solar power.


Cook Strait - Tidal power

1 The power generated by tidal marine turbines varies as the cube of the

tidal speed. Because the tidal speed doubles, eight times more tidal power is produced during spring

tides than at neaps.
