The WaveRoller system consists of a plate anchored to the seabed that oscillates back and forth through a hinge thanks to the movement of the waves. The kinetic energy produced is collected with a piston pump and converted into electricity by a generator attached to the device or by a closed hydraulic system in combination with a generator / turbine system. It is a modular system, its capacity can be gradually increased.
The WaveRoller is installed in an area close to the coast at a depth of 8-20 m, where the optimum point of the wave is captured, as well as avoiding the most violent storms. Because larger waves break naturally before entering nearshore areas, WaveRoller ® devices evade devastating waves that could damage offshore facilities.
The best resources in wave energy are concentrated in the coastlines, where the majority of the population lives and is also where there is the greatest demand for renewable energy. AW-Energy has several projects started on coasts with large wave energy centers such as Portugal, France or Ireland.
The Finnish company is negotiating with the Mexican government to develop a wave energy pilot project in the Baja California Sea, which would allow Mexico to be a leading country in the American continent in this renewable technology.
The project they want to develop in Mexico would be 20 MW, about 60 Waveoller units in the state of Baja California.
In Peniche, Portugal, a pilot project whose purpose is to explore wave energy has received a grant of 10 million euros from the European Investment Bank (EIB), with the support of the Horizon 2020 program.
Sweden is the first country to commercially produce wave energy
