【Ten Years of Rapid Development in Chemical Engineering Equipment】1351–2023: World’s first 300MW compressed air energy storage power station compressor unit was produced
Thread Content
On September 20, 2023, the compressor unit, which is the core equipment for China Energy Engineering Group’s world’s first 300MW-class compressed air energy storage project that does not require supplementary combustion, was fully manufactured at the Shaanxi Gas Turbine Group’s facility. Four large trucks carrying the core equipment for compressed air energy storage, considered to be key technologies of major countries, slowly made their way to the construction site, marking a significant breakthrough in the industrialization of the core equipment for the world’s first 300MW-class non-supplementary combustion compressed air energy storage demonstration project. In compressed air energy storage systems, the compressor serves as the \"heart\" of the system; it represents the most challenging aspect in terms of technology, and its performance directly determines the overall energy storage efficiency. Developing compression technologies that can handle large flow rates, offer high efficiency, and allow for high exhaust temperatures has always faced significant technical barriers, and such technologies are considered to be the key obstacles in compressed air energy storage. Eight large turbo compressor units are arranged in two rows, with four compressor units in each row connected in series, achieving a comprehensive polytropic efficiency of around 90%. This represents a significant innovation in key equipment achieved by our country in the field of 300MW-class large-scale, long-duration compressed air energy storage; it also marks the beginning of the engineering installation phase for the world’s first 300MW-class compressed air energy storage system. Meanwhile, 700 kilometers away in Yingcheng, Hubei, a region known for its reeds, this world-class compressed air energy storage demonstration project is being developed in an orderly and vigorous manner. It is expected that the compressor unit, this key piece of equipment, will arrive at the project site within the next week for installation and commissioning.
Shanxi Gas Turbine Group signs contract for the world’s first 300MW artificial cavern compressor air energy storage project. Publication date: November 20, 2023. Source: Shanxi Gas Turbine Group’s official website. Recently, Shanxi Gas Turbine Group signed a contract with China Energy Engineering Group for the “Gansu Jiuquan 300MW compressed air energy storage power station demonstration project”; it will supply multiple large-scale compressor units as well as related auxiliary system equipment for this project. The 300MW compressed air energy storage power station demonstration project in Jiuquan, Gansu is the world’s first compressed air energy storage system of the 100-megawatt class using artificial caverns. Upon completion, the project will promote the coordinated development of other industries, facilitate the coordinated operation of various energy sources, and enable the scaled, industrialized, and intensive development of new energy equipment manufacturing. It serves as a model for establishing a green energy industry base in Jiuquan and the northwest region, as well as for advancing the development of an innovative power system in China. Leveraging its more than 50 years of experience in the energy sector, Shaanxi Gas Turbine has conducted in-depth research on compressed air energy storage technology, and now possesses the capability to develop and produce compressors with capacities ranging from 10 to 400 MW, along with relevant implementation experience in this field. In response to the requirements of the 300-megawatt compressed air energy storage power station demonstration project in Jiuquan, Gansu, SHANGGU provided the user with the EISS4.0 solution, which is characterized by low carbon consumption and smart functionality. This solution includes compressors that offer the largest capacity and best performance in the field of energy storage, helping the user to reduce costs, lower carbon emissions, and increase profits.
Thank you, President Yu, for your hard work; thumbs up!
