The Danish wave energy start-up Weptos to develop first full-size plant – opens a new R&D center

The Danish start-up Weptos develops free-floating wave energy converters. Achored to the seabed, the Weptos system is built up of a number (~20) of asymmetric rotors that move independently, the rotors are connected to a single axle, which drives a generator. The many rotors using the same axle, makes the generator rotating movement uninterrupted. Under normal operating conditions the rate of axle turn is about 20 to 40 rpm. A possible generator solution could therefore be existing technology from commonly used wind turbines. The span of the system is flexible so that the capacity is optimized at all conditions; in a calm sea the span is wide, in high seas the span is narrowed - this also reduces the stress of the structure.
