TRL 7/8: Open Water System Testing & Demonstration & Operation
Technology Description The OEBuoy device uses wave energy to compress air in a plenum chamber and pump it through an air turbine system. This isolates the power conversion system from the seawater and also provides a high-speed air flow to the turbine. The device is a floating system with the mouth of the OWC facing away from the wave direction. This results in high energy efficiencies at the operating point because of the motions of the float system relative to the waves.
