Beijing, July 2, Xinhua News Agency (Reporter Liu Liang) - On July 2, it was learned that the fully seawater floating photovoltaic project of Sinopec Qingdao Refining & Chemical Company has been completed and put into operation, making it the first industrial operation fully seawater environment floating photovoltaic project in China. Linked with the previously put into operation pile foundation water surface photovoltaic project, it has become the largest water surface photovoltaic power station of Sinopec in China at present.

It is reported that the above overall project generates 16.7 million kilowatt-hours of green electricity annually, which can reduce carbon dioxide emissions by 14,000 tons, equivalent to planting an additional 750,000 trees.

The floating photovoltaic power station is connected to the water area and sea area, generating electricity by utilizing the surface space of the sea. The project is located in the Qingdao Refining & Chemical Company's hydrogen energy 'production-research-plus' demonstration park, with advantages such as zero emissions, high efficiency, and low cost. It covers an area of about 60,000 square meters, with an installed capacity of 7.5 megawatts. The design of the photovoltaic panels synchronizing with the tidal rise and fall to shorten the distance between the panels and the water surface maximizes the use of seawater for heat dissipation, thereby increasing the power generation efficiency by 5% to 8% through the cooling effect.

Previously, Qingdao Refining & Chemical Company has built China's first 'carbon neutral' hydrogen station and the first factory-scale seawater hydrogen production project. The comprehensive completion and operation of the water surface photovoltaic project has formed a new energy industry pattern of 'photovoltaic power generation for green electricity and green electricity for green hydrogen', laying a resource foundation for green hydrogen refining and green hydrogen transportation industries. The next step for Qingdao Refining & Chemical Company is to further expand and build a 23-megawatt floating photovoltaic project.
