Implementation of tidal turbines in Quebec
- 1. Study of the implementation of tidal turbines in QuebecPhilippe KOUAMÉ Project DirectorDominique PelletierJuly 29th 2010
- 2. Outline of the presentationIntroductionMethodologyResults et discussionConclusion et prospects
- 3. Introduction
- 4. IssueWhere does the implementation of tidal turbines will be profitable?
- 5. What would be the necessary ways?
- 6. What would be the cost of electricity from these tidal turbines?
- 7. What would be the advantages and drawbacks of this technology?MethodologyUnderstand the working of a tidal turbineState of the technologyIdentify issues and socioeconomic impactsIdentify issues and environmental challengeInventory the potential for tidal turbines
- 9. Working of a tidal turbine
- 10. TechnologicalprogressHydrohelix (France)HS1000 , Hammerfest Strom (Norway)Unit cost: 325 000 $Nominal power : 200 kWUnit cost: 16 215 000 $Nominal power: 1 MWAnnual output:700000 kWh/an
- 11. Skerries project, MCT (UK)Turbine Gorlov - GCK Technology Inc (USA)Nominal power: 1.5 MW for 2 turbines
- 12. Open center turbine- OceanenergyInc (USA-Florida)Nominal power: 2.4 MW
- 13. Davis Hydro Turbine - Blue Energy (Canada) Nominal power :5 à 25kW
- 14. Issues and socioeconomic impactsCost 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. 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. 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. Job creation for the north area of Quebec where unemployment is around 10%Issues and environmental challengesNo GES emission
- 18. Minor Perturbations of the seabedwhichneed to beinvestigateddeeply
- 19. Installation stepcould have strong impacts with excavation and blasting
- 20. Electricityprovided in the north of Quebec by diesel powerplantResults for du Saint-Lawrence estuary
- 21. Results for Hudson strait
- 22. Usable Strategies in QuebecFor Saint-LawreenceEstuaryTidal turbines totalyimmersed and set on the seabedFor the region of Hudson StraitTidal turbines totalyimmersed and set on the seabedFor the Ungava BayTidal turbines totalyimmersed and set on the seabed
- 23. Avantages of the technologyClean and inexhaustible source of energy
- 25. No dependence on weather
- 26. Visual impact almost non-existentDrawbacks of the technologyRepaircanbedifficult for some turbine models
- 27. Installation maybedifficults for the site with a waterflowabove3.5 m/sExcavation needsthe use of boat thatcanlean on seabed
- 28. ConclusionTidal turbine’s implementation is less expensive than an hydroelectic dam’s implementationAfter payback on investment, the cost of electricity is identical or even less expensive than electricity from hydroelectricityFor the environmental impacts, more researchs should be done and implementation projects should be submited to the BAPE
