On the 27th, the turbine—the pivotal component of the world's largest compressed air energy storage power station, namely the Huaneng Jintan Salt Cave Compressed Air Energy Storage Phase II Project—was successfully lifted and installed, marking the official commencement of the main equipment installation phase. Serving as the heart of the compressed air energy storage power station, the turbine is capable of transitioning from startup to full-load operation within a mere 10 minutes. Notably, its core components are entirely domestically produced, and it currently boasts the highest single-unit output and the largest air intake flow in China. The project, initiated in Changzhou, Jiangsu, in December of the previous year, aims to construct two sets of 350-megawatt non-combustion units, encompassing a total volume of 1.2 million cubic meters. Once completed, the project will have the capacity to store 2.8 million kilowatt-hours of electricity per charge. It is anticipated to save 270,000 tons of standard coal annually and curb carbon dioxide emissions by 520,000 tons. Compressed air energy storage operates by compressing air during periods of low grid demand and subsequently releasing it to generate electricity during peak demand periods, thereby achieving efficient energy storage.
