Abstract
Energy storage technologies will play a crucial role in increasing both the efficiency, as well as the availability, of renewable energy, thus decoupling real generation from expected generation and from consumption demands. Compressed air energy storage (hereinafter “CAES”) enables the efficient and cost-effective storage of large amounts of energy. The development of CAES in a salt dome offers several technical and economic advantages. In order to reduce the inherent risk associated with the definition and selection of subsurface structures, this study proposes a multi-criteria algorithm based on the analytic hierarchy process. In this case, the study was focused on the Basque-Cantabrian basin (Spain) where it is possible to identify up to 11 surfacing diapiric structures. These peculiar characteristics allow considering new research topics: establish a new definition of energy storage capacity, considering not only the storage of compressed air at great depth, but also the definition of mini-CAES.
