The WEC devices developed at ITRI utilized an energy conversion hydraulic power system. Wave energy is first absorbed with a buoy and converted into mechanical energy. This is done through a low friction and high-efficiency mechanism, which is patent pending. The mechanical energy is further converted into electrical power through a hydraulic motor and a power generator. The WEC device is designed in such a way that it could be installed with different anchor type depending on site condition. The key technology is the capability to design and develop a WEC device with respect to required power and specific wave climate.
