Makers/Companies

• Clean Current (h-axis, shrouded rotor)• GCK (vertical-axis, Gorlov helical rotor)• Lunar Energy (h-axis, shrouded rotor)• Marine Current Turbines (h-axis, open

rotor)• Open Hydro (h-axis, open rotor, rim-

drive)

What

• As the turbines turn they create energy. This happens both as the tide comes in and as the tide goes out. The turbines' energy is then routed to storage generators and sent out through power lines to feed the power needs of thecommunity.

When• Was being pioneered in 2001 by the UK• The first ocean current turbine, Seaflow,

was installed in May 2003• SeaGen was installed 2006 and the

world’s first commercial tidal current energy turbine is also an environmental success. The tidal turbine, designed and deployed by Marine Current Turbines Ltd (MCT) and located in Northern Ireland’s Strangford Lough.

Where• First started in the UK• Turbines must be placed in areas where

current speeds are 4 to 5 knots (2 to 2,5 m/s)
