Implementation of tidal turbines in Quebec

  1. 1. Study of the implementation of tidal turbines in Quebec<br />Philippe KOUAMÉ<br /> Project Director<br />Dominique Pelletier<br />July 29th 2010<br />
  2. 2. Outline of the presentation<br />Introduction<br />Methodology<br />Results et discussion<br />Conclusion et prospects<br />
  3. 3. Introduction<br />
  4. 4. Issue<br /><ul><li>Where does the implementation of tidal turbines will be profitable?
  5. 5. What would be the necessary ways?
  6. 6. What would be the cost of electricity from these tidal turbines?
  7. 7. What would be the advantages and drawbacks of this technology?</li></li></ul><li>Methodology<br />Understand the working of a tidal turbine<br />State of the technology<br />Identify issues and socioeconomic impacts<br />Identify issues and environmental challenge<br />Inventory the potential for tidal turbines<br />
  8. 8. Results and discussion<br />
  9. 9. Working of a tidal turbine<br />
  10. 10. Technologicalprogress<br />Hydrohelix (France)<br />HS1000 , Hammerfest Strom (Norway)<br />Unit cost: 325 000 $<br />Nominal power : 200 kW<br />Unit cost: 16 215 000 $<br />Nominal power: 1 MW<br />Annual output:700000 kWh/an<br />
  11. 11. Skerries project, MCT (UK)<br />Turbine Gorlov - GCK Technology Inc (USA)<br />Nominal power: 1.5 MW for 2 turbines<br />
  12. 12. Open center turbine- OceanenergyInc (USA-Florida)<br />Nominal power: 2.4 MW<br />
  13. 13. Davis Hydro Turbine - Blue Energy (Canada) <br />Nominal power :5 à 25kW<br />
  14. 14. Issues and socioeconomic impacts<br /><ul><li>Cost of the project for the installation of Eastmain 1-A (918 MW) : 5 Billions $ , comparatively to 3.5 Billions $ for the installation of a tidal turbine farm of 1000 MW (MCT)
  15. 15. The price of the kWh from tidal turbine would cost around 7¢ and 11¢ (BB&V 2006) comparatively to 6.60¢ for the city of Montreal at the same time (Hydro Québec)
  16. 16. After the payback of investment, the cost of the kWh would be equivalent and even less expensive than electricity from nuclear energy and hydropower (Blue Energy)
  17. 17. Job creation for the north area of Quebec where unemployment is around 10%</li></li></ul><li>Issues and environmental challenges<br /><ul><li>No GES emission

  23. 23. Avantages of the technology<br /><ul><li>Clean and inexhaustible source of energy
  24. 24. Predictablemany centuries ahead
  25. 25. No dependence on weather
  26. 26. Visual impact almost non-existent</li></li></ul><li>Drawbacks of the technology<br /><ul><li>Repaircanbedifficult for some turbine models
  27. 27. Installation maybedifficults for the site with a waterflowabove3.5 m/s</li></ul>Excavation needsthe use of boat thatcanlean on seabed<br />
  28. 28. Conclusion<br />Tidal turbine’s implementation is less expensive than an hydroelectic dam’s implementation<br />After payback on investment, the cost of electricity is identical or even less expensive than electricity from hydroelectricity<br />For the environmental impacts, more researchs should be done and implementation projects should be submited to the BAPE<br />
