Abstract

Renewable energy sources are sporadic and unpredictable, which makes mass adoption extremely difficult. A viable option that is specifically designed to handle this problem is compressed air energy storage, or CAES. It provides large-scale energy storage capabilities. Air is compressed during off- peak hours and stored in subterranean chambers as part of this two-step process. The air that has been stored is released when there is a demand peak, which turns a turbine and produces energy. Notably, CAES has a number of benefits over alternative storage options. Since it can keep energy for long periods of time, it is an excellent tool for managing the erratic output of renewable sources. Its intrinsic scalability also makes it adaptable to a variety of grid requirements. By offering backup power and enabling the smooth integration of renewables, CAES also helps to maintain grid stability. Moreover, its economic feasibility is highlighted by its comparatively elevated efficiency in contrast to alternative solutions. In order to fully realize the promise of renewable energy sources and promote a more robust and sustainable energy future, CAES offers a dependable and scalable method of storing energy.
