BEIJING, July 13 (Xinhua) — China has made a major breakthrough in clean energy technology with the launch of the world's most powerful floating direct-drive wind turbine.
The 17-megawatt turbine, jointly developed by state-owned enterprises China Huaneng Group (CHG) and Dongfang Electric Corporation, officially rolled off the production line on Thursday in the coastal city of Fuqing, east China's Fujian Province, CHG confirmed to Xinhua News Agency on Saturday.
One of its power units can generate 68 million kWh of environmentally friendly electricity per year, which will be enough to supply electricity to approximately 40 thousand households.
According to CHG, the demonstration test of the wind turbine will take place in waters near the city of Yangjiang in southern China's Guangdong Province.
The giant machine, with an operational availability of over 99 percent, has a record rotor diameter of 262 meters, and the blade capture area during rotation is about 53 thousand square meters, which is equivalent to 7.5 standard football fields. At the same time, the height of the central hub of 152 meters is comparable to a 50-story residential building.
This wind turbine can withstand extreme marine conditions, including waves over 24 meters high and typhoons of force 17. Unique stabilization technology allows continuous power generation even when the floating platform is tilted at extreme angles.
Liu Xin, director of the offshore wind energy department at China Huaneng Alternative Energy Technology Research Institute, highlighted the turbine's adaptability, noting that its integrated intelligent sensing system provides holistic stability control for safe and efficient operation in the complex and variable deep-sea environment.
A team of researchers has made a technological breakthrough in floating wind energy system coupling modeling technology and high-fidelity model testing technology.
Notably, all major components, including blades, generators and transformers, are made in China, and the design includes, for the first time, Chinese-made large-diameter main shaft bearings.
This technological breakthrough opens the door to exploiting China's vast deep-sea wind resources. According to the Energy Research Institute of the National Development and Reform Commission of China, the depth of China's coastal waters ranges from 5 to 50 meters, where the country has about 500 GW of electricity from wind energy resources, while similar resources on the deep-sea shelf are about 3 to 4 times larger.
Data from the World Wind Energy Council (GWEC) highlights the global importance of these resources, showing that more than 80 percent of the world's offshore wind resources are located in waters deeper than 60 meters.
Floating wind technologies and solutions will further unlock the potential of deepwater offshore wind energy in the future, GWEC data shows.
According to GWEC, the global installed capacity of floating wind turbines is estimated to reach 278 MW by the end of 2024, with Norway, the UK, China and France leading the four largest markets in this field. -0-
