Wave Country Notes
Since the beginning of the 1980s, China's wave energy research has concentrated mainly on fixed and floating oscillating water column devices. In 1995, the Guangzhou Institute of Energy Conversion of the Chinese Academy of Sciences successfully developed a symmetrical turbine wave-power generation device for navigation buoys rated at 60 W. Over 650 units have been deployed along the Chinese coast, with a few exported to Japan.
Other wave energy projects in China include:
a shoreline OWC at Shanwei in Guangdong province consisting of a two-chambered device with a total width of 20 m, rated at 100 kW began operating in September 1999;
a 5 kW Backward Bent Duct Buoy (a floating OWC with the opening to the OWC chamber pointing towards the land) in association with Japan;
a shoreline pivoting flap device (Pendulor) developed by Tianjin Institute of Ocean Technology of the State Oceanic Administration;
an experimental 3 kW shoreline OWC was installed on Dawanshan Island (in the Pearl River estuary), which is being upgraded with a 20 kW turbine.
