How did it all begin?
During a fishing trip in the summer of 2006, inventor Daniel Ehrnberg, was inspired by the twirling motion of the water around the oars and began to think about how a floating wind turbine could be vertical and connected to a rotating floater. Ehrnberg had experience working with wave power and an interest for renewable energy and now he wanted to find out how the ocean winds could be used as a source for renewable energy. In a matter of years different tests with smaller prototypes were performed and in late 2012 SeaTwirl was founded. In 2015, SeaTwirl’s prototype S1, a 3okW wind turbine, was installed in the sea off Lysekil – Sweden’s first floating wind turbine!

About S1
SeaTwirl deployed the 30kW floating wind turbine S1 off the coast of Lysekil, Sweden in July 2015. S1 has been connected to the grid and tested according to plan since its deployment. The project was implemented by a small and ambitious group on a limited budget. S1 is one of the very few floating wind power projects in the world to have been in the water for a longer period of time. It has withstood harsh weather conditions, autumn and winter storms reaching hurricane wind speeds.
