Compressed air energy storage (CAES) is a large-scale energy storage system with long-term capacity for utility applications. This study evaluates the economic feasibility of CAES pre-selected reservoirs case studies for the Portuguese electricity system.
The modular compressed air energy storage system proved to be stable and bounded with a safety factor of two for foundation, which is the predominant factor that holds the entire system.
Among the different ES technologies, compressed air energy storage (CAES) can store tens to hundreds of MW of power capacity for long-term applications and utility-scale. The increasing need for large-scale ES has led to the rising interest and development of CAES projects.
A suitable geological site for compressed air energy storage is given by a highly permeable porous formation and a tight cap rock to prevent the buoyant rise of the air (see Fig. 1). In northern Germany, anticline structures suitable for CAES can be found in a variety of settings (Baldschuhn et al. 2001).
The design aspects of the proposed modular compressed air storage system (CAES) were executed to eliminate the multistage air compression process and overcome the adverse safety issues of underground caverns prevailing in the conventional system.
This paper proposes the experimental analysis of a small-scale modular compressed air storage system, wherein the storage structure is remodeled and arranged within the tower structure. The proposed storage system is designed to connect the air compressor directly with the turbine through a coupling shaft to reduce intermediate losses.
