Compressed Air Energy Storage (CAES) for Hongsha Hydropower: Evaluating Technologies for a Sustainable Transition

Abstract

Compressed Air Energy Storage (CAES) has attracted considerable interest in recent years due to its crucial function in integrating renewable energy and regulating power systems. Its advantages include large storage capacity, relatively low cost, and adaptability to diverse application scenarios, making it a promising solution for addressing the intermittency and volatility of renewable energy sources such as solar and wind power. As a mature and reliable energy storage technology, CAES can effectively smooth power fluctuations, support grid balancing, and provide emergency backup power. In the global context of transitioning toward a low-carbon economy and sustainable development, CAES is increasingly recognized as a critical technology to optimize power system operations, improve energy resilience, and ensure grid stability, thereby facilitating the broader adoption of clean energy. The compressed air energy storage system can significantly enhance the capacity of renewable energy consumption and alleviate the pressure of peak-to-valley difference in the power grid. In the future, its potential for large-scale application in large-scale power systems deserves continued attention and in-depth research.
