Abstract
China is developing tidal current energy generators to Help expand the Country's use of marine renewables. Some preliminary studies have been done to determine the theoretic average tidal current power of these marine areas. One hundred and thirty channels in China have been studied. China has abundant marine resources under its jurisdiction, with about three million square kilometers of ocean area, 18,000 kilometers of mainland coastline and 14,000 kilometers of island coastline. One of the earliest devices to be developed was the 70-kilowatt floating vertically oriented tidal current energy generator Wanxiang-I, designed by Harbin Engineering University and completed in January 2002. Chinese academic institutions are developing strong new designs to harness China's vast tidal energy resources, and many of these devices already demonstrating their worth in the water. Wanxiang-I was installed in Guishan, China, in an area 40 to 70 meters deep and 100 meters from the coast.
... The Technology Readiness Level(TRL) of tidal current energy technology is about Level 7 in China. More than 20 turbines have completed sea trial and the maximum power reached MWs level [7]. The MWs demonstration plant operated by Zhejiang Zhoushan LHD Energy Co., Ltd. ...
Marine renewable energy is a new type of energy that is inexhaustible, clean, low-carbon and renewable. China is rich in marine renewable energy. It is of great significance to promote the development of marine renewable energy industry since it can strengthen the construction of ecological civilization, facilitate the implementation of the “Carbon Peaking and Carbon Neutrality” strategy, ensure energy security, and drive the development of the marine economy. Europe, the United States and other countries attach great importance to the development of the marine renewable energy industry. In recent years, they have constantly increased financial investment and policy support for this industry, and boosted its integrated development together with the blue economy including offshore wind power and marine aquaculture, which served as an important reference for China to develop the marine renewable energy industry. China’s marine renewable energy industry is at the critical stage of industrialization, and it is necessary to accelerate related work such as policy support, technology R&D, and scale application, so as to lay the foundation for driving our marine renewable energy industry to the growth stage.
