The ASTERIx-CAESar project, funded by the European Commission, is focused on the development of a novel high-efficiency CSP plant with integrated electricity storage solution, combining air-based central receiver system and Compressed Air energy Storage (CAES). Through this agreement, Hatch. The design portion of this study lays the groundwork for building the compression phase of a solar-powered compressed air energy storage system that will integrate a rotary compressor, ultracapacitors, and a turbocharger to serve as proof-of-concept for an environmentally. This technology strategy. Air storage vessels vary in the thermodynamic conditions of the storage and on the technology used: 1. Constant volume storage ( caverns, above-ground vessels, aquifers, automotive applications, etc.
