Wave power plant

A wave power plant is a facility that uses the energy of the waves (hence the name) and swell to produce electricity. It is therefore a system that uses marine renewable energies.

Different mechanisms can be used to capture and transform the potential and kinetic energy from these oscillations of the sea: pendulums and floaters activate pneumatic or hydraulic jacks, water or air compression systems connected to turbines, etc.

Currently, projects exploring these different channels struggle to overcome the practical constraints encountered. There are very few plants of this type actually in operation.
