WaveRoller – One of the Leading Technologies for Wave Energy Conversion

Date: February 24, 2015 at 12:46 GMT

WaveRoller is one of the most advanced technologies to convert ocean energy to electricity. The device is an oscillating wave surge converter that converts ocean waves to electricity by a flap that moves and absorbs the energy, see Figure 1. The back-and-forth movement of the flap is converted to rotation of a generator thanks to a hydraulic system. The electricity output of the generator is then transferred to the shore by a subsea cable. WaveRoller operates in near-shore regions at depths of between 8 and 20 meters, approximately 0.3-2 km from the shore. It is anchored to the seabed, and depending on tidal conditions it is mostly or fully submerged. A series of WaveRoller devices can be deployed into an array to create a wave farm. Since WaveRoller is constructed as modular individual units, there is no natural upper limit to the number of devices that can be used in an array, therefore offering a high level of scalability and reliability.
