Integrating compressed air energy storage with wind energy system – A review

Abstract

- With an increasing capacity of wind energy globally, wind-driven Compressed Air Energy Storage (CAES) technology has gained significant momentum in recent years. However, unlike traditional CAES systems, a wind-driven CAES system operates with more frequent fluctuations due to the intermittent nature of wind power. Consequently, the design and operation of wind-driven CAES systems must address such a complex and dynamic behavior. Considering the growing interest in wind-driven CAES systems, a comprehensive and systematic review of the existing literature on their design and operational characteristics is appealing. Therefore, this study aims at filling this research gap by examining the existing literature on the configuration, sizing, and operation/scheduling of wind-driven CAES systems. This review also aims at highlighting the underlying assumptions and methodologies employed in previous studies on wind-driven CAES systems. Given the challenges faced by several CAES projects, which were discontinued due to geological and economic constraints, it is imperative to conduct comprehensive feasibility studies to support the development and implementation of wind-driven CAES systems. Additionally, there is a growing necessity to explore the feasibility of small-scale CAES systems, focusing on their potential to bolster energy security and resilience for small or remote communities in distributed energy systems. By examining the existing literature and highlighting the gaps in current research, a number of insights are provided serving as foundations for future investigations in this field.
