Driven by the "dual carbon" goal, my country's energy structure transformation is moving from land to deep blue. Recently, Sinopec Qingdao Refining and Chemical's all-seawater floating photovoltaic project was completed and put into use. This project is my country's first all-seawater floating photovoltaic project. This "blue Great Wall" standing on the coast of the Yellow Sea not only marks my country's key breakthrough in the development of marine new energy, but also highlights the deep logic of technological innovation empowering the energy revolution.
The project is located in the Qingdao Refining and Chemical Hydrogen Energy "Production Research and Addition" Demonstration Park, covering an area of about 60,000 square meters and an installed capacity of 7.5 MW. The project uses all N-type solar panels. The floating photovoltaic structure uses a dynamic design in which the photovoltaic panels rise and fall synchronously with the tide, shortening the distance between the panel and the water surface to 1/10 of the traditional pile-based structure. The near-water layout forms a unique "seawater cooling effect", which reduces the operating temperature of the components by 3-5℃ and increases the power generation efficiency by 5%-8%. After the project is completed, it will generate 16.7 million kWh of green electricity annually, reduce carbon dioxide emissions by 14,000 tons, and reduce investment by about 10% compared with traditional pile-based photovoltaics. The completion of this project not only marks a key breakthrough in my country's development of marine new energy, but also opens up a new path for energy transformation in coastal cities, islands and offshore oil and gas platforms.
my country has a coastline of 18,000 kilometers and 3 million square kilometers of jurisdictional waters. The potential for marine new energy development is huge, and it is expected to exceed 1 billion kilowatts. In 2025, the policy clearly proposed "supporting deep-sea aquaculture and building offshore ranches". With the continuous increase in national policies, the "blue granary" strategy has been steadily promoted, and the integrated development of "photovoltaic + marine ranches" has become the current mainstream trend. As the core supplier of this project, in recent years, we have focused on the innovation and application of offshore photovoltaics. The offshore floating photovoltaic power generation system uses independently developed aluminum-like polymer composite materials. Compared with traditional HDPE floating power stations, it has significant comprehensive advantages, including high environmental protection, high weather resistance, no fear of ultraviolet rays, high temperature and salt spray erosion, excellent safety, convenient construction, etc. It can significantly increase the power generation per unit area, outstanding wind and wave resistance, and stable operation under harsh sea conditions, bringing customers the greatest value benefits.
