Australia based Energetech will soon begin supplying clean electric power from Australia’s first commercial wave-generated power station located 100 yards off shore in the beach community of Wallongong.
Wave power generation, a developing technology, holds tremendous potential for clean energy production. An added benefit of the Energetech technology is its capability to create both clean electrical power and drinking water. The Wallongong station will eventually supply power to up to 500 nearby homes and can desalinate water, a precious commodity in drought ravaged Australia, for almost an equal number.
Ocean waves provide the densest and most constant of all natural power sources. In the Engergetech prototype, electricity is generated when waves wash into a funnel facing the ocean, driving air through a pipe and into a turbine.
When fully operational the plant will create 500 kw of clean energy while producing 2,000 litres of desalinated water per day.
Plans are to build 10 additional plants off the south Australian coast. The ultimate hope for the technology is to produce power at less than the cost of fossil fuel powered generation without the accompanying emissions and with the tremendous added benefit of the creation of drinking water for coastal communities.
Another innovative company in the wave energy area is AW-Energy, a Finnish company that is developing a different approch to wave power with its WaveRoller system. WaveRoller captures the kinetic energy created subsurface by the motion of waves, using a specially designed bottom-mounted moving ‘wing’. The captured energy is converted to electricity using traditional technologies. The beauty of this system is that the device remains sub-surface with no above surface structure. The technology is currently in being tested and expanded in the Gulf of Finland.
