A transformative project in the realm of energy storage is underway, promising to reshape the landscape of renewable power supply. The ambitious initiative is set to construct two massive sets of 350MW compressed air energy storage (CAES) units, totaling a striking 700MW. With an impressive storage capacity of 2.8GWh, the system will utilize a salt cavern capable of holding up to 1.2 million cubic meters of compressed air. This innovative design will allow for a discharge duration of four hours, significantly enhancing energy accessibility.
Although the project’s completion timeline remains undisclosed, it boasts the title of the largest CAES system worldwide, based on several criteria including power, capacity, and efficiency. Jointly developed by China Huaneng and the China Salt Group, the project represents a notable advancement in energy technology.
In CAES systems, air is compressed and stored, then released through a specialized heating mechanism that expands the air. This process ultimately drives a turbine generator to produce electricity. Support for this pioneering project comes from esteemed institutions like Tsinghua University and the Xi’an Thermal Power Research Institute.
Earlier this year, another similar project entered the spotlight in Hubei, celebrated for its 300MW capacity. As CAES technology continues to evolve, it is increasingly recognized as a cornerstone in long-duration energy storage initiatives not just in China, but globally.
