TECHNIQUE
To be able to convert wave energy into electricity, the converter needs to be located at the ocean surface. This is where most energy is available.
The Havkraft Wave Energy Converter (H-WEC)
Havkraft’s Havkraft Wave Energy Converter (H-WEC) is the core component in all our solutions. When we open the side of the converter, we see that the waves have been converted into efficient water pistons in several chambers. That is why we call it a wave energy converter.
This conversion is fantastic because it means that we have captured the different waves’ frequencies in several chambers, and this makes it possible to use them for power generation. There are several pistons working independently, all driven by different wave heights and wave lengths in the ocean. In other words, the converter picks up small, medium and large waves in the same design.
The rise and fall of the water columns results in the generation of pressure and vacuum, which in turn is captured by the turbine at the top. The turbines always rotate in the same direction as the air flow is controlled at both the top and bottom of the turbine with guiding vanes. This means that the system will always be in operation when there is motion in the ocean.
The H-WEC’s size depends on the solution and its intended operational location. The same applies for the number of chambers. Each chamber has its own turbine and generator that convert the kinetic and potential energy in the waves into electricity.
Our H-WEC is the most flexible wave energy device in the world. It is fully scalable to any wave climate, it is independent of materials and it has a longevity that secures energy production for decades with a minimum of maintenance.
