Our Technology

The WaveEL™ buoy is the power converter.

The standard WaveEL™ buoy is eight meters in diameter, in the water line. A vertical tube – 3.5 meters in diameter – passes through the buoy centre, reaching down 28 – 38 meters below the surface. Inside the tube is a water piston attached to a hydraulic system, and power take-off system, which convert the wave-induced, up and down motion to electricity. The electric power is exported via a patented low-voltage cable to the WaveEL™ Hub where it is transformed to medium high voltage and sent via sea cable to the power user.

The WaveEL™ buoy is moored with poly ropes to heavy gravity anchors on the ocean floor. The mooring design gives the buoy freedom to move almost unimpeded vertically, while safely securing it on station.
