China to Dominate Offshore Wind by 2030, US Faces Supply Chain Challenges
China is set to dominate the global offshore wind market by 2030, according to Rystad Energy. The country is projected to account for 45% of the world's offshore wind capacity. Meanwhile, the USA is facing challenges in its offshore wind sector, with investments declining and supply chain reliance on China.
By the end of 2025, the global offshore wind capacity is expected to reach 16 GW, with two-thirds of these projects being developed in China. A significant contributor to this growth is the China National Offshore Oil Corporation (CNOOC), which is expanding its offshore wind portfolio. The company plans to commission a 1.5 GW project in Hainan CZ7 before 2030.
In contrast, US renewable energy investments have decreased by 36% year-on-year in 2025. This decline is partly due to the issuance of stop work orders for major offshore wind projects, such as Ørsted's Rhode Island farm and Equinor's 704 MW New York project. The USA is aiming to reduce its reliance on Chinese supply chains for offshore wind, but this presents challenges. Rystad Energy notes that around 25% of manufacturing sites for key components are located in China, making it difficult to create an alternate, renewables-driven supply chain to compete with China.
By 2030, China's dominance in the global offshore wind market is expected to be substantial, with 45% of the world's offshore wind capacity. Meanwhile, the USA faces challenges in its offshore wind sector, including declining investments and supply chain reliance on China. These factors highlight the global dynamics and competition in the offshore wind industry.
