Ocean Energy USA will leverage lessons learned from previous quarter-scale tests that have led to design improvements for a full-scale validation of its Ocean Energy Buoy at the Wave Energy Test Site (WETS). The Ocean Energy Buoy is an oscillating water column device that works by pumping air by the natural rise and fall of ocean waves through an air turbine system to generate electricity. The U.S. Department of Energy (DOE) and the U.S. Navy will collect baseline performance data, gain operational experience, and identify key cost drivers for oscillating water column devices. Other research objectives include validating device durability in the open ocean environment, measuring power output at full scale, and evaluating the levelized cost of energy produced by the device.
