Offshore wind turbines with the world's largest single power capacity and longest rotor diameter have been developed by China State Shipbuilding Corporation Limited (CSSC) in East China's Shandong Province.
Its development is a milestone of the global offshore wind power industry and is expected to promote China's energy structure transformation and contribute to reaching its "dual carbon" goals of peaking carbon dioxide emissions by 2030 and attaining carbon neutrality by 2060.
The newly-developed ultra-large offshore wind turbines have a sweeping area of about 53,000 square meters, equaling the area of seven standard football pitches. At full wind speed, each revolution can generate 44.8 kilowatt-hours of power, and the single unit output can reach more than 74 million kWh of clean power annually, meeting the annual power consumption of 40,000 households of three.
The output equals that produced by burning 25,000 metric tons of standard coal and reduces 61,000 tons of carbon dioxide emissions, which has significant energy-saving and emission-reduction effects.
Multiple breakthroughs were made during development of the wind turbines, which include integrated design and smart control technology.
The offshore wind turbines are expected to effectively reduce sea area occupation and the number of machine sites, which can lower the cost of offshore wind farm projects and lay a solid foundation for development of the offshore wind power industry in deep waters.
The development of the turbines will also support the upgrading of the offshore wind power industry chain, drive development of component industries like wind power blades, gearboxes, generators, and converters, create a large-scale wind power industry cluster, and form a new growth point for China's economic development.
It will also improve the country's overall manufacturing level of wind power equipment, lead the upgrading of the wind power industry, and produce significant social and economic benefits.
