Israel wave energy developer SDE Energy Ltd. has agreed to supply wave power plants to China, with the first installation planned off Guangdong Province in southern China.
SDE Managing Director Shmuel Ovadia said two joint venture companies formed to implement the agreement plan to build an initial model in Guangzhou. It is to be deployed by the end of 2009. Once the model has been proven, Ovadia said the companies will begin installing the plants in China.
The Chinese government must approve the installations and is to purchase electricity generated by the plants, Ovadia said. Under the July 2008 agreement, construction of the wave power plants is to be financed by investors from Hong Kong and China.
SDE’s technology converts the vertical motion of waves into hydraulic pressure, which is then used to generate electricity. (HNN 11/26/08) The units, which are installed on breakwaters, rest on the surface of the ocean and are connected to the breakwater by a hydraulic arm. The units can produce energy from both the rising and falling of waves.
Ovadia said, to date, SDE has built eight model wave power plants, with financial assistance from the chief scientist of Israel’s Ministry of Industry and Trade. The most recent model tested was a 40-kW unit that operated for nearly a year.
