Description | The vertical motion of ocean waves is converted in linear or rotational motion for driving electrical generators by means of a PTO system. These technologies can harness energy from a wave front much larger than the horizontal width. These systems are designed for the implementation of wave farms. |
Physical Requirements | Minimum wave height: 0.5 m Bathymetry: 7 – 25 m |
Dimensions | Minimum distance: 25 m Height: 3.5 - 7 m Height : 1.5 – 2.5 m Width: 3 – 5 m |
Technical aspects/Turbine: | Rated power: 10kW Electricity production: 40 – 60 MWh/yr |
Points of attention: | -Productivity – actual wave energy potential (variability and seasonality of wave characteristics such as height and frequency) -Connection to the grid -Possible impacts on marine ecosystems -Possible impacts on navigation & fishing (interference with navigation routes) -Maintenance costs (corrosion by seawater) -Variability of wave direction |
