Aquamarine Power's Oyster wave power technology captures energy in nearshore waves and converts it into clean sustainable electricity.  Essentially Oyster is a wave-powered pump that pushes high-pressure water to drive an onshore hydroelectric turbine.

Wave power is generated by the wind blowing over the surface of the ocean far out at sea.  The action of the wind transmits energy into waves.  These waves can travel vast distances with little energy loss before breaking on the shore.  Our Oyster device is designed to harness this energy and convert it into electricity.

Mechanical offshore device

The Oyster wave power device is a buoyant, hinged flap that is attached to the seabed at depths of between 10 and 15 meters, around half a kilometer from the shore.  This location is often referred to as the nearshore.

Onshore electricity generation

Oyster's hinged flap, which is almost entirely underwater, pitches backward and forwards in the nearshore waves.  The movement of the flap drives two hydraulic pistons which push high-pressure water onshore via a subsea pipeline to drive a conventional hydro-electric turbine.

In the future, subsea pipelines will connect multiple Oyster wave energy devices to a single onshore plant.  Ultimately Oyster will be installed in wave farms of several hundred connected devices generating hundreds of megawatts of electricity.

Nearshore location

By locating oysters on the nearshore, we are able to capture a high proportion of the energy available in the ocean whilst avoiding the severe storms which occur further out to sea.
