The Solution

Waves4Power green energy solutions are based on harvesting the free power of the ocean waves. The power is converted into electricity and distributed to the end user. It’s as simple as that…

The Waves4Power WaveEL system is based on many years of experience, testing, and countless marine service operations. The heart of the wave power system is our point absorber, the WaveEL buoy, where the energy of the waves is converted into electrical power.

The WaveEL buoy – a gigantic pump

  • A buoy with a long vertical tube (the acceleration tube) passing through it
  • A water piston inside the tube connected to a power conversion system
  • A mooring system allowing the buoy free vertical movement while securing it on station
  • A dynamic cable connecting the buoy to the connection hub and then via sea cable to the end user

The power generating buoy is a Point Absorber and as such is defined as a device with small horizontal dimensions in relation to the wavelength of the waves from which it is extracting energy. Due to their size, point absorbers are known to survive well in the ocean as they do not fight the waves, but ride them.

The characteristic feature of the WaveEL buoy is the patented long acceleration tube. The tube – which is open at both ends – goes directly through the buoy and extends 30-35 meters below.

As waves rise and lower the buoy with the attached tube, they will move differently – slightly out of phase – with the water column in the tube. By placing a piston in the tube, connected to a hydraulic conversion system, a gigantic pump is created.
