The Drakoo wave energy converter is a technological device that uses the motion of ocean surface waves to generate electricity.
Principle
The Drakoo WEC does not fall under any of the usual wave energy converter classifications: its working principle, based on a twin-chamber oscillating water column system, is to transform waves into a continuous water flow which drives a hydro turbine generator.[1][2]
Development history
after being patented in 2008, the Drakoo technology has successfully been tested in NTU lab and, subsequently, in the deep wave flume of NAREC in 2012(UK).[3]
On December 23, 2016, Hann Ocean Energy, the Singapore wave developer company which invented and patented the technology, announced the first successful power production during a trial in its testing facility in Nantong, with a peak power output of 3.8 kW at a wave height of 0.6m.[4]
The technology continuously increased its performances along the years, reaching firstly a peak output power of 9.3 kW in November 2017 and of 11.2 kW in March 2018. Moreover, during the World Future Energy Summit 2018, in Abu Dhabi, Hann Ocean Energy reported about sales inquiries from the Persian Gulf for the application of the Drakoo WEC for wellhead platforms.[1]
