en.Wedoany.com Reported - The Department of Marine Strategic Planning and Economics of China's Ministry of Natural Resources released the "2025 National Seawater Utilization Report" on the 8th, showing that the scale of China's seawater desalination projects has been increasing year by year. As of the end of 2025, there were 167 seawater desalination projects nationwide, including 68 projects with a capacity of 10,000 tons per day or more.
Xiang Wenxi, Director of the Institute of Seawater Desalination and Multipurpose Utilization, Ministry of Natural Resources (Tianjin), told reporters on the same day that in recent years, water-scarce coastal regions have been steadily advancing the construction of seawater desalination projects, with the scale growing annually. In 2025, there were 167 seawater desalination projects nationwide, with a total capacity of 3.077 million tons per day, an increase of 86.4% compared to 2020. These projects are distributed across 10 coastal provinces (autonomous regions and municipalities), including Liaoning, Tianjin, Hebei, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong, Guangxi, and Hainan. They have effectively ensured the industrial water needs of major coastal industries such as thermal power, nuclear power, steel, and petrochemicals, as well as the domestic water needs of water-scarce coastal islands and cities. Meanwhile, the seawater desalination industry chain is continuously extending towards green and low-carbon development, with initial progress in the intensive utilization of seawater resources.
The report indicates that in 2025, seawater cooling water usage nationwide was primarily concentrated in coastal thermal power, nuclear power, and petrochemical industries. According to estimates, as of the end of 2025, the annual seawater cooling water usage reached 193.36 billion tons, an increase of 5.024 billion tons compared to 2024. By the end of 2025, all 11 coastal provinces (autonomous regions and municipalities) had seawater cooling projects in operation. In 2025, the annual seawater cooling water usage in Liaoning, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong, and Guangxi each exceeded 10 billion tons.
Xiang Wenxi stated that the "15th Five-Year Plan" outline explicitly calls for expanding emerging marine industries such as seawater desalination, charting the course for advancing seawater utilization during the "15th Five-Year Plan" period. Currently, multiple large-scale seawater desalination projects in Hebei, Shandong, and other regions are progressing steadily, with new business models and formats for seawater desalination rapidly taking shape, moving towards higher quality, greener, and more international development.
