China Energy Construction Group Co., Ltd. (hereinafter referred to as China Energy) News. The company is located in five key projects in Chaoyang City, Liaoning Province and Jiuquan City, Gansu Province.In the same, about S $ 4 billion).China can build the first batch of compressed air storage power stations in China within China.
According to the surging news report, the above projects include the demonstration project of the Liaoning Chaoyang, Gansu Jiuquan 300 MW compressed air storage power stations, the 200,000 kilowatt source network loading project of the Gansu Jiuquan Economic Development Zone,The integrated utilization project of the source of the source of the source and the comprehensive utilization of the Gansu Jiuquan Landurge and the hydrogen energy comprehensive utilization demonstration project, the total installed capacity is 2555 MW.
Among them, China Energy Construction Division of Liaoning Chaoyang and Jiuquan, Liaoning, and Gansu Jiuquan's two 300 MW compressed air storage power stations demonstration projects.The first (set) 300 MW artificial chamber compressed air storage project, which cracked a worldwide problem that compressed air storage was restricted by geographical conditions.
The large -scale grid connected with new energy such as wind power photovoltaic and other new energy sources to ensure that the storage energy storage used to ensure the stable operation of the power grid has received more and more attention.Among various types of energy storage technologies, China can build the investment in large -capacity and long -term physical energy storage such as compressed air, and is leading the development, construction and industrialization of compressed air storage.
Song Yuwen, deputy secretary of the Party Committee and general manager of China Energy Group, said in an interview that under the background of the national "double carbon" strategic, the power system is gradually transforming into the four major: source, network, lotus, and storage of storage.The format, and the long -term energy storage of large capacity is a key link to support the construction of a new power system.
It is reported that compared with pumping energy, the scale of the single machine compressed energy storage has reached 300 MW level, and the system comprehensive conversion efficiency has reached more than 70%, which is consistent with the mainstream pumping storage; its power cost isThe capacity cost is equivalent to pumping, but the site selection of compressed energy storage is more flexible than pumping. The construction cycle of about two years is far lower than the 8 -year cycle of pumping capacity.There are issues such as immigration relocation and ecological environment. Compared with the energy storage of lithium batteries, the capacity of compressed energy storage is low, and there are no problems such as resource development bottlenecks, cycle life limit, and safe and environmental risks, which have high environmental friendship.
Song Yuwen said that the two demonstration projects of Chaoyang and Gansu Jiuquan in Liaoning have adopted China to build a compressed air storage power station system solution -300 MW -class non -supplementary combustion compressed air storage system, which can bear "New Energy access to the power grid "optimizer" "The stabilizer of the safe operation of the power system", "the router of user -side energy management", "UHV Green Power Delivery adapter", "retired thermal power cleaning and transformation device", "super charging treasure"The role.
Zhu Zhide, the technical person in charge of the technical head of the Energy Storage and Development Division of China Energy and Development Division of China Energy, said that after the completion of the two projects of Jiuquan and Liaoning Chaoyang in Gansu, it can be in terms of peak adjustment, frequency adjustment, rotary use and even voltage support.The regional power grid provides rich auxiliary services, relieves the pressure of power supply, and effectively improves the level of renewable energy consumption. In terms of system conversion efficiency, response speed, power grid support capacity, parameters are first -class in China.
"At present, the business model of domestic energy storage projects is still in the initial stage of formation. The relatively mature ones are two electrical prices, power market transactions, new energy base support construction, independent energy storage, etc.Energy storage is a business model of independent energy storage. It is one of the current models for large -scale energy storage costs. It is the improvement and progress of the new energy configuration energy storage power station.Capacity indicators saves large expenses of self -investment, and energy storage power stations have also achieved profitability. "Zhu Zhide said that Gansu Jiuquan Project is a further exploration of China's ability to build energy storage projects.
According to its introduction, since 2022, China has built the construction of compressed air storage projects that has started construction.Gansu Jiuquan 300MW -class compressed air storage power station and Liaoning Chaoyang 300MW -level compressed air storage power station total 1250MWh.At the stage of the planning and implementation stage, there are Gansu Jinchang 300MW -level compressed air storage power stations, Liaoning Tieling 300MW -level compressed air storage power stations, etc., and completed the selection point layout of more than 50 compressed air energy storage power stations.
"We plan to deploy 100 compressed air energy storage power stations across the country." Zhu Zhide said that China can continue to strengthen energy storage technology innovation and promote large -capacity compressed air storage power stations and other key key points.The research and development and demonstration of technical equipment, as well as the complementary and coordinated operation of energy, promote the large -scale, industrialized, and intensive development of new energy and equipment manufacturing.
