A Scottish company is set to build the world's first commercial cheap energy wave farm, it has emerged.
Aquamarine Power has raised £6 million in its latest round of fundraising to facilitate the next phase of development of a wave device known as the Oyster.
The Oyster, which has been undergoing testing the European Marine Energy Centre in Orkney since last November, is designed for use in water close to the shore, up to 12 metres in depth.
The device features a hinged flap connected to the sea bed, with each wave moving the flap to drive a hydraulic piston, delivering high pressure water to an onshore turbine.
An improved version of the original device is expected to deliver 250 per cent more power with a 50 per cent increase in footprint.
Aquamarine has won the rights to develop the Brough Head wave farm off the coast of Scotland, which will be able to provide enough energy for around 190,000 homes.
