Sotenas Wave Power Project

Seabased’s WEC uses a simple, ring-shaped buoy tethered by a steel and synthetic line to a power unit housed on the seabed and based on the technology developed at Uppsala University. As the waves rise and fall, the buoy pulls up and down on a cable attached to a linear ‘translator’ —a kind of rotor—that uses a permanent or ferrite-magnet system encased in stators to generate power.

The project was cancelled in October, 2017, but there are no plans for decommissioning the device. Instead, the device will be kept in place to be used as an artificial reef and as a site for further research and testing purposes.
