Unlimited Clean Energy with The Wavestar machine

Rising to the Challenge

Our monthly report about power performance


The concept was invented by sailing enthusiasts Niels and Keld Hansen in 2000. The challenge was to create a regular output of energy from ocean swells and waves that are 5-10 seconds apart. This was achieved with a row of half-submerged buoys, which rise and fall in turn as the wave passes, forming the iconic part of Wavestar’s design. This allows energy to be continually produced despite waves being periodic.

The machine’s unique storm protection system, one of the many patented aspects of the design, guarantees the machine’s sea survivability and represents a real milestone in the development of wave energy machines. Wave energy will play a crucial role in securing our energy future, but only machines that can withstand the strongest storms will survive.

Climate and environmental issues demand swift diversification to multiple renewable sources in order for us to fulfill our future energy needs. Wavestar will work in harmony with other clean energy methods to support the alternative energy movement and ensure a continuous supply of clean energy. Imagine what we can do together.


Wavestar is applying for Horizon 2020

Wavestar is requesting EU for support through Horizon 2020 in May. Wavestar has formed an industrial consortium with the purpose to produce the first full-scale 1 MW Wavestar WEC to be tested commercially. The consortium behind the EU application consists among others of STX, IFP EN, DNV and Aalborg, Gent and Cantabria Universities.

Wavestar presents four years of operation results at ICOE in Halifax.

We are, as the only wave energy developers in the world, documenting several years of continuous production in the sea. This we present November 4 at the world's largest conference for ocean energywhich brings together industry, researchers and energy companies. Wavestar intends to share its experience on operation and maintenance over 4 years and present our vision for the future. The presentation will be available here after the conference.

Wavestar is testing new promising PTO system

Wavestar is in the process of documenting the impressive results of the new PTO (power take off) system. The system will increase the efficiency of the wave energy machine significantly. This is a crucial factor in making wave energy a competitive source of renewable energy in line with offshore wind. Wave motion between 0-3 meters is simulated on a full-scale test apparatus at Aalborg University and measure the power effect of our newly developed digital hydraulic system. The test results can be transferred directly to the real full-scale machine.
