In partnership with the Directorate of Shipbuilding Systems (DCNS), Fortum is currently testing on the coast of Portugal the second generation of a prototype he called "waveroller". This module of 10 meters long and wide is supposed to produce 300kwatt thanks to the waves formed by the movements of the swell. "Basically," says Philippe Stohr, "this idea came from a Finnish professional diver who, when looking for a wreck and seeing a door beating at the bottom of the sea, wondered what energy could be drawn from it. . Today, we are developing the third generation which should be able to produce the equivalent of 1,5 at 2 MWatt, ie the production of a wind turbine. "
Knowing that a wind turbine produces energy at a rate of 2000 at 2500hours / year, the waveroller would achieve an average of 4000hours a year. "
In the near future, we can easily imagine parks consisting of about twenty waverolls each, located about fifteen meters below sea level, in place of offshore wind turbines often accused of disfiguring the oceanic landscape of dimensions French. It would then be totally in the logic of the green sectors of the future.
