Construction of CNPC’s Dushanzi photovoltaic molten salt energy storage demonstration project is accelerating rapidly

On April 16, reporters went to the Gobi desert, located about 25 kilometers east of the Dushanzi urban area, and saw workers using drills to create rows of holes nearly two meters deep in the ground. Some of the holes are being incorporated into reinforced concrete structures and reinforced to create ground supports, on which photovoltaic panels for power generation can be installed later. At present, the construction of the photovoltaic area and the molten salt area of the project is advancing at full speed, with all stages of work progressing in an orderly manner and being implemented efficiently. The construction unit strictly follows the construction plan, scientifically allocates human resources, materials, and mechanical equipment, details the construction milestones, strengthens quality and safety oversight, and makes every effort to meet the project completion goals. It is understood that the core components of this project include photovoltaic power plants, molten salt energy storage systems, and turbine upgrades. Upon completion, the project will serve as the core support for Dushanzi Petrochemical in establishing a zero-carbon heating system based on molten salt energy storage, with gas supply serving as a supplementary mechanism. “In response to the group company’s overall requirements for low-carbon transformation and the upgrading of energy systems, the photovoltaic section of the project will be completed by December 30, meeting the conditions for power generation. ”Wu Wenhui, project manager of the photovoltaic molten salt energy storage demonstration project at Lianjian Company, said. As a key green and low-carbon project that was implemented first in China Petroleum’s new materials sector for refining and chemical processing, this photovoltaic molten salt energy storage demonstration project represents a practical application of Daishanzi Petrochemical’s overall strategy of \"clean substitution, strategic replacement, and green transformation\" set forth by China Petroleum. It also serves as a vital component of the company’s efforts to transform its energy structure, and it is the first major step taken by Daishanzi Petrochemical to advance its strategy of eliminating coal use. Once this project is put into operation successfully, the relevant departments of the company will plan to expand the molten salt energy storage system in order to increase the steam supply capacity. At the same time, the coal-fired boilers will be converted into gas-fired boilers, so that in normal operating conditions, all steam demand can be met by the molten salt energy storage system, while the gas-fired boilers will serve as a backup source of heat during extreme weather conditions. Taking the construction of the photovoltaic molten salt energy storage demonstration project as an opportunity, the company will continue to focus on sustainable and low-carbon development, striving to become a model for the clean replacement of coal-fired boilers, and contributing to the development of China’s green energy industry as well as the achievement of the **\"dual carbon\" goals.
