Types of Tidal Power Generation • Barrages • Tidal Streams

Tidal Barrage • Turbines • Sluice gates • Embankments

Bulb Turbine

Straflo or Rim Generator Turbine

Tubular Turbine

Benefits • Renewable • Can help protection of ports in

storms • Can help navigation for shipping • Reliable, more so than solar or wind

Environmental factors • Change in currents • Change in sediments • Salinity and quality of water • Migratory species

Tidal streams • Instead of damming estuaries the

tidal currents are harnessed using wind like turbines

Main methods of current generation • Marine current generator • Stingray • Tidal fence

Benefits of Tidal stream • Far less intrusive • Can generate same amount of power as wind with smaller blades moving slower due to density of water • More available sites • More reliable than wind • Usually less expensive than barrage

Problems • Fouling • Relatively new technology • Don’t get the funneling effect of barrages
