A new milestone for marine energy was achieved recently when UK based Wave and Tidal Technologies company Aquamarine Power Ltd signed a 1,000 MW (1 GW) Development Agreement with the renewable energy development division of Scottish and Southern Energy, Airtricity. Aquamarimes's Wave Power device, called Oyster, is a near shore hydroelectric wave power system. Still at the full scale prototype stage, the Oyster is based around a large movable buoyant barrier structure that is mounted on the seabed in depths of 10 – 12 m (33 – 40 ft) and pivots like a gate.

Renewable Energy Company Oceanlinx has re-deployed its full-scale wave energy conversion unit at Port Kembla in Australia. First deployed in 2005, the unit has been undergoing planned refurbishment and modifications for the past several months. The Oceanlinx wave generator, which is an Oscillating Water Column (OWC) device capable of generating peak power outputs of between 100 Kw and 1.5 MW, is one of six installations around the world currently being trialed.

Wave and wind power hybrid for off shore wind farms

Bringing together the benefits of two eco-friendly forms of power generation, Scottish company Green Ocean Energy has developed a wave power machine that attaches to an offshore wind turbine. The system, known as the Wave Treader, comprises two 20 m (66ft) long floats molded from GRP (Glass Reinforced Plastic) at ocean level attached to a wind turbine tower by 50 m (165 ft) long pivoting beams. As the floats move up and down in response to constant wave action, the arms move hydraulic cylinders attached to the beams by levers, which in turn spins a hydraulic motor connected directly to an electric generator.
