Tidal and river energy are among the key sources of renewable energy available on our planet. Tocardo is harvesting this energy and working to provide clean and sustainable energy for future generations.

Green power

Believe it or not, waters from the seas and oceans could provide more than the needed power for our developments

They are cheap, sustainable and mostly available. The only slack is in man, because man seldom focus. If only man has realized its usefulness in the early stages, then we would not be burdened now.

The Rance Tidal Power Station Saint Malo

The Rance Tidal Power Station Saint Malo

The Rance Tidal Power Station Saint Malo

In the bay of St Malo the tide is one of the highest int the World about 10m peak in to 13m at the equinoxes of March or September.

The French has tackled this clean free cosmic energy by the construction a tide operated power station at the mouth of the tide River La Rance – the first in the world!

Tidal

Opened in 1966 as the world’s first tidal power station end over 45 years, the largest tidal power station in the world until the South Korean Sihwa Lake Tidal Power Station surpassed in 2011.

  • Its 24 turbines reach peak output at 240 megawatts and average 62 megawatts, a capacity factor of approximately 26%. At an annual output of approximately 540 GWh, it supplies 0.012% of the power demand of France.
  • The barrage is 750 m (2,461 ft) long, from Brebis point in the west to Briantais point in the east. The power plant portion of the dam is 332.5 m (1,091 ft) long and the tidal basin measures 22.5 km2 (9 sq mi).

New Turbines

In 2012, the French utility company, EDF, deployed the first of four underwater turbines in the Bay of St Malo (watch this video). If initial tests are successful, the site at Paimpol-Bréha  will become the world’s first tidal ‘power station’, feeding up to six Megawatts of renewable energy into the French electricity grid. The oldest Tidal Power Station and again this €40 Million project, clearly demonstrates France’s commitment to renewable energy.

Hydropower

Tidal power is produced by building a dam across the opening of a tidal basin. The sluice gate opens to allow the tide to flow into the basin. When closed, the sea level drops and standard hydropower techniques generate electricity from the water elevated in the basin. The Rance power station, situated south of St Malo (France) is the unique tidal power station in the world providing electricity for commercial use.

It can generate 240 megawatts of power, with minimal environmental impact, and provide electricity for 223,000 inhabitants. The tide fills and empties the Rance estuary twice a day and the amplitude can reach the record height of 13.5 meters. This infoclip shows: – Rance power station and estuary – Pylons – St Malo at night.

Why Wave Power?

Unlike solar and wind energy which, due to their intermittent nature, are primarily suited to peak power supply, a number of factors favor wave energy as part of an energy portfolio including:

  • the inherent high availability, reliability and predictability of wave activity
  • the fact that any variability in wave activity happens gradually and with significant warning, making issues of grid interfacing manageable
  • the proximity of favourable wave energy sites to ultimate end users, thereby minimising transmission issues. Notably, approximately 60% of the world’s population lives within 60 kilometres of a coast; and
  • the energy density of the wave resource (water is 800 times more dense than air).

Ocean Power

In addition, this can operate efficiently in swell in the 1 to 2 meter wave height range, greatly increasing the number of potential base-load sites globally. For example, much of Australia receives significant wave heights in excess of 1 meter 100% of the time.

Ocean Energy – Wave Power Station

Potential

The worldwide resource of this kind of energy has been estimated to be greater than 2 TW. Locations with the most potential for wave power include the western seaboard of Europe, the northern coast of the UK, and the Pacific coastlines of North and South America, Southern Africa, Australia, and New Zealand. The north and south temperate zones have the best sites for capturing the power of the oceans. The prevailing wester lies in these zones blow strongest in winter.

Blue Energy from Holland

Blue Energy from seawater

Green power plant Blue Energy generates continually, contrary to solar and wind energy, which are both dependent on availability and the weather.

Blue Energy will succeed in generating energy for 8 cents per kilowatt-hour for half a million households in the Netherlands.

In this test plant at the Afsluitdijk the joining of river and sea water is used to generate green power. This is because by using cleverly designed membranes (special filters), you can generate electricity directly from the difference in salt concentration. Researchers from the University of Twente’s MESA+ research institute supplied the knowledge for the membranes and the technology for this power station.

In the future it will be possible to generate ten percent of the Dutch energy consumption via this technology. With its large rivers such as the Rhine and the Meuse, the Netherlands has great potential in this area. The University of Twente makes an important contribution to the research and the further development of the plant.

Cheap clean blue energy

The expectation is that Blue Energy will succeed in generating energy for 8 cents per kilowatt-hour (without subsidies). Solar and wind energy are currently a lot more expensive, energy from petroleum is still cheaper at the moment.

In addition, Blue Energy can be generated continually, contrary to solar and wind energy, which are both dependent on availability and the weather. The total quantity of electricity that could be generated on the Afsluitdijk is equal to 1200 billion AA batteries a year, or, in other words, sufficient for the energy requirements of 500,000 households. It is potentially possible to generate the entire electricity consumption worldwide with Blue Energy.

Dutch King Willem-Alexander put the world’s first blue-energy RED power plant to use on November 26, 2014. The plant is located on the closure dam Afsluitdijk, the Netherlands, and produces electricity directly from the difference in salt concentration in the surface water on each side of the dam.

Technical feasibility

Theoretically, with 1m3/s river water and an equal amount of sea water approximately 1 MW of renewable electricity can be recovered.

The pilot plant on the Afsluitdijk is to produce 50 kW blue-energy per hour and will show the technical feasibility in real life conditions using fresh IJsselmeer water and salt water from the Wadden Sea.

Big potential energy source

At the current location on the closure dam Afsluitdijk, the potential production of blue-energy can be sufficient for the energy requirements of 500,000 households.

An exploration of suitable rivers in the world shows that there is a potential electricity production of 1,600 TWh annually.
