The curiosity of two sailing enthusiasts who, by dint of embarking, insisted on finding a way to enjoy the “Mighty forces under the sea” is at the origin of Wavestar, a pioneering initiative that enables uninterrupted wave energy production and that it also does so with a unique resistance to meteorological adversities which, on many occasions, have interposed themselves in the use of this inexhaustible source of resources.

After ten years of researching Niels and Keld Hensen’s idea, Wavestar took on the challenge of converting the capture of energy from waves that occur every five to ten seconds, with a system of submerged row buoys that rise and fall in turns, which allows the energy capture to not stop despite the oscillation of the waves.

Thanks to a hydraulic mechanism, the energy collected by these buoys is transferred to a generator which produces electricity. In addition to ensuring that fluctuating sources such as waves produce energy in a stable manner, this system represents an important advance in terms of the safety of structures, which are equipped with an anti-storm system that guarantees the maintenance of the equipment in the most adverse weather conditions.

“Wave energy will play a fundamental role in securing the energy of the future, but only machines capable of withstanding the harshest storms will be able to survive”They say of the company, which bought the rights to the idea from the Hensen brothers, who continue, now as consultants, to support the project.

But Wavestar is not satisfied with this progress and aspires to lay the foundations for real energy parks for the use of different energy sources sustainable. “It can be wind and waves, but also solar energy …”, says Laurent Marquis, technical manager of a project which sees its objective in the “Construction of the first parks in which the systems for capturing energy from the sea are located around the wind turbines. If the waves and the wind meet everyone wins, they say.

After years of measuring the results of its proposal to increase energy capture from sea waves, Wavestar is rebuilding the system to update it and increase its float count. More, the company has requested the support of the European Union through its Horizon 2020 program with the aim of building its first large-scale prototype, for which a consortium has been set up that includes the University of Cantabria, among other institutions.

“We are ready to build a great system”, supports in this line Marquis, who sees in the sum of the different sources of sustainable energy the energy response of the future. “We have to learn from each other. Instead of competing, we must build together a new concept that is promising for the future ”.
