Transcript of "Tidal power"

  1. 1. The Tidal Power Alexander Mitrofanov ICT Praha 2012
  2. 2. Index• Introduction• Tides• Tidal power and wave power• How it works• The difference between the Two• Types of tidal plants• Pros and Cons of Tidal Power• Currents sites of tidal power plants• Kislaya Guba Tidal Power Station• References
  3. 3. Introduction Tidal power, also called tidal energy, is a formof hydropower that converts the energy of tides into useful forms of power - mainly electricity. This is the only form of energy whose source is the moon.
  4. 4. TidesTides are the rise and fall of sea levels causedby the combined effects of the gravitationalforces exerted by the Moon and the Sun andthe rotation of the Earth.
  5. 5. The high tide
  6. 6. The low tide
  7. 7. TidesHigh and low tides in use
  8. 8. Tidal power and wave power
  9. 9. Wave Power Wave power devices take energy directly from surface waves or from pressurefluctuations below the surface. Wave power isof course powered by waves. As a wave goes by, the buoy rotates and transforms mechanical energy into electrical energy.
  10. 10. Wave Power
  11. 11. Wave Power
  12. 12. Wave Power
  13. 13. Wave Power
  14. 14. Pros and Cons of Wave Power
  15. 15. Wave Power Pros Cons• Consistent Power • Device Breakdown Pollution-Free • High Initial Costs• Low Operating Costs • Noise• Renewable• Minimal Visual Impact
  16. 16. Tidal PowerTidal power is actuated by a turbine under water that spins making the mechanicalenergy to electrical throw a generator that send the electrical energy to the shore.
  17. 17. Types of tidal plants Tidal Barrage Tidal current turbinesAre Typically dams, built Make use of the kineticacross on estuary of bay energy of moving water to power turbines in a simular way to wind turbines that use wind to power turbines
  18. 18. Types of tidal plantsTidal Barrage Tidal current turbines
  19. 19. Tidal BarrageThe Rance tidal barrage in North-West France is the largest in the world
  20. 20. Tidal current turbines
  21. 21. Tidal current turbines
  22. 22. Significant benefits from using Tidal Energy include:• Electrification of isolated communities• Generation for the grid Regrowth of coral reefs using mineral accretion technology• Substitution of imported petroleum used to generate electricity
  23. 23. Pros and Cons of Tidal Power
  24. 24. Tidal Barrages Pros Cons• Mature technology • High costs of that has been around construction for nearly 50 years • Environmental impacts• Reliable energy source. on marine life • Low power output in comparison to other energy source like coal and nuclear power plants .
  25. 25. Tidal Current Turbines Pros Cons• Able to utilize both ebb • Tidal current turbine and flood tides technology is young in• Tidal current turbines its development are not large massive • Installation and dam structure. maintenance challenges • Environmental impacts are still being tested
