A WaveRoller device is a plate
anchored on the sea bottom by its lower part. The back and forth
movement of bottom waves moves the plate, and the kinetic energy
produced is collected by a piston pump.
This energy can be converted to electricity by a closed
hydraulic system in combination with a hydraulic motor/generator
system.
WaveRoller is a modular concept. In practice this means that the plant capacity is formed by connecting a number of production modules into a WaveRoller plant.
Each module consists of 3-5 wave elements installed
into a common
generation system.
Due to the modular design, the WaveRoller plant can be taken into production gradually, module by module. Thus the scalability is good, and there is no technological upper limit for the plant capacity. Modules are also easily maintained and electricity production
of the plant can continue also during module maintenance.
