looking at the development status of the wind power industry from the country’s first industrial park “carbon neutrality” certificate——

the wind comes from the sea and sends calls to millions of homes

standing at the niutouwei pier in shapu town, fuqing city, you can see 59 wind turbines standing on the vast expanse of blue sea, shaped like windmills and colored like white feathers. the three blades of the wind turbine convert the gusts of sea breeze into green electricity. the generated electricity is raised to 220 kilovolts through an offshore booster station, then input into the power grid through submarine cables, and finally sent to thousands of households.

turning our attention from the sea back to the land, the fujian three gorges offshore wind power international industrial park, which is behind the offshore wind airport, is also a pioneer in green development. in 2021, the country's first industrial park "carbon neutrality" certificate was issued here, once again refreshing the public's understanding of energy conservation and emission reduction in the entire offshore wind power industry chain.

as my country's first full-industry chain offshore wind power industrial park, the fujian three gorges offshore wind power international industrial park covers an area of ​​1,000 acres with a total investment of approximately 4 billion yuan. the park has introduced domestic and foreign wind power equipment giants such as goldwind technology, dongfang electric, jiangsu crrc, the fourth hydropower bureau and danish elm, forming a complete industry of wind turbines, wind turbine structural parts, wind turbine assembly, and blade production. the chain structure has enabled mass production of wind power equipment, and its production capacity, output, and technical level rank first in the country and even among the best in the world.

in recent years, the industrial park has successively rolled off the production lines of elm's 107-meter ultra-long blades, goldwind technology's 16-megawatt offshore wind turbines, dongfang electric's 18-megawatt offshore wind turbines, etc., and has gradually developed into a gathering place for my country's offshore wind power technology innovation.

"a 16-megawatt wind turbine is estimated to generate 34 kilowatt-hours in one revolution, generating 66 million kilowatt-hours per year, which can be used by 36,000 households of three for one year." deputy director of the electric power operation department of fuqing strait power generation co., ltd. manager wang jiabin told reporters that from the initial 6.7 mw to the current 18 mw offshore wind turbine, major countries have frequently updated their equipment, and the industrial park’s wind turbine manufacturing technology has been iteratively upgraded, constantly refreshing the asia-pacific region and even the world’s offshore wind turbines. wind power equipment manufacturing records.

in june 2023, dongfang electric and academician xie heping’s team jointly conducted the world’s first offshore wind power in-situ direct electrolysis hydrogen production technology without desalination seawater pilot test, which was successful at the xinghua bay offshore wind farm in fuqing. this is the first time in the world that hydrogen production has been achieved without desalination of seawater. dongfang electric combined with offshore wind power technology to turn inexhaustible seawater resources into a steady stream of hydrogen energy, which may change the path of global energy development in the future.

affected by the "narrow tube effect" in the taiwan strait, the annual average wind speed in fujian's offshore waters is 8 to 9 meters per second, and the average annual utilization hours of offshore wind power reaches more than 3,500 hours. so far, fuqing xinghua bay offshore wind farm has generated more than 5.2 billion kilowatt-hours of electricity, which is equivalent to reducing coal consumption by about 1.57 million tons and reducing carbon dioxide emissions by about 3.83 million tons. last year, the power generated by offshore wind farms in the three gorges and fujian regions reached 2.555 billion kilowatt hours.

as a strategic cooperation project between china three gorges corporation and fujian province, fujian three gorges offshore wind power international industrial park makes full use of fuqing's superior wind resources and good light resources to build an intelligent microgrid project integrating rooftop photovoltaic systems, wind turbine systems and intelligent control. the company provides green and clean energy. after all the smart microgrid projects are put into operation, the annual average power generation will be 53.6 million kilowatt hours, which is equivalent to saving nearly 6,590 tons of standard coal every year and reducing carbon emissions by about 38,000 tons.

innovation is the driving force behind green development. "in the past, the main components of wind turbines such as main shafts and gearboxes needed to be imported. for 16-mw and 18-mw wind turbines, all major components have been replaced by domestic products." sheng lei, deputy general manager of fujian three gorges offshore wind power international industrial park operation co., ltd. explain.

at present, the three gorges wind power industrial park has completed and put into operation a number of offshore wind power projects including phase i and phase ii of xinghua bay in fuqing, changle area a, pingtan offshore and zhangpu phase ii. among them, xinghua bay phase i wind farm is the world's first international high-power prototype test wind farm; xinghua bay phase ii wind farm is the first place where the largest 10-megawatt prototype in asia-pacific was put into use, marking the entry of my country's offshore wind power industry. in the double-digit era; changle area a wind farm is my country's first "double 40" (water depth 40 meters, 40 kilometers offshore) wind farm. 10 mw wind turbines have been put into mass production, and the 16 mw prototype has taken the lead in demonstration and application, setting the standard for offshore wind power. providing valuable experience to march into the deep sea; zhangpu phase ii wind farm is the first project in the country to use 16 mw large-capacity offshore wind turbines in batches, and is also the first (set) major technical equipment project in the energy field of the national energy administration's third batch supporting projects.
