Sydney-based company Oceanlinx (formerly Energtech) is to take part in creating the world's first large-scale wave energy farm, 16km off the coast of Cornwall.

The $58 million project, to be installed within two years, will grant each of four companies a lease of 2 square kilometres of sea area to test their technology on a large-scale. The four different types of wave energy generators will be connected to hub on the sea floor. Cables running from the  hub to land will feed 20 megawatts of electricity (enough to power 7500 homes) into the national power gird

A year ago, Oceanlinx's wave energy technology was named by the International Academy of Science as one of the ten most outstanding technologies in the world. In Australia, the company has a pilot plant at Port Kembla, a feasibility study for King Island and is negotiating to establish a 27 megawatt wave energy project off the Victorian coast at Portland. In the United states, Rhode Island wants a pilot plant, Hawaii has signed a deal for three of the company's floating wave energy converters and a power company on the Oregon coast is negotiating with Oceanlinx to build a 15 megawatt wave energy park. Mexico's Federal Electricity Commission, the world's biggest electricity provider, is conducting a feasibility study for two new wave plants using the Australian technology.

Oceanlinx's success is based on the Denniss-Auld turbine invented by the company's founder, Dr Tom Denniss. ''We have more interest around the world in the technology than we can service at the moment. The market for us is unlimited,'' Denniss says.
