China completes building world’s largest 26-MW offshore wind turbine

World's largest 26-megawatt offshore wind turbine has been unveiled in east China's Fujian Province on Saturday, a fully domestically designed and manufactured unit which symbolizes a milestone achievement in the country's green energy development.

The 26-megawatt offshore wind turbine boasts remarkable dimensions. Its hub center is 185 meters high, equivalent to a 63-story residential building. The designed rotor diameter exceeds 310 meters, with a swept area exceeding 10 standard football fields, making it the largest turbine globally in terms of both capacity and size.

One of the key achievements of this project is the fully localized design and manufacturing.

"We have overcome the bottleneck of relying on imported bearings for direct-drive systems. We have achieved complete independence and control in both bearings' control systems and the supporting components. Whether in terms of technical specifications or efficiency and reliability, we are at the forefront of the world," said Wang Jun, vice general manager of the Dongfang Electric Corporation, the manufacturer.

The turbine is designed specifically for medium- to high-wind-speed offshore areas. With an average wind speed of 10 meters per second, a single unit can generate 100 million kilowatt-hours of clean energy annually.

With high efficiency, this turbine is enough to power 55,000 households for a year, saving more than 30,000 tons of standard coal and cutting carbon dioxide emissions by over 80,000 tons.

"In a 500-megawatt offshore wind project, using a 26-megawatt turbine compared to an 18-megawatt turbine would reduce the total number of turbines by over 30 percent and lower the cost per kilowatt-hour by more than 10 percent. This offers strong equipment support for achieving cost parity in offshore wind power," said Wang.

ROK president calls for learning lesson from anti-aggression history

The Republic of Korea (ROK) and China should cherish the historical experience of jointly resisting aggression and continue to work together for a prosperous future, said ROK President Lee Jae Myung.

At the invitation of Chinese President Xi Jinping, Lee will pay a state visit to China from Jan 4 to 7. It will be Lee's first visit to China since he took office last year.

In an interview with China Media Group (CMG) in Seoul on Wednesday, Lee said that humanity must learn from the past to prevent the tragedy of war from repeating itself.

"While pursuing their own national interests to the fullest extent, countries must not harm the national interests of others, but should coexist peacefully. The act of invading other countries and massacring their people for one's own benefit must never be repeated. History of humanity often repeats itself, therefore we must learn from the past. In this regard, I believe the historical experience of ROK and China in resisting aggression and fighting together is invaluable. Of course, while historical experience is important, we cannot remain stuck in the past. For a better future for the people of both countries, we need to continuously explore possibilities for working together towards the future," said the president.
