Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. At a utility scale, energy generated during periods of low demand can be released during peak load periods. [1] The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany. . This technology strategy assessment on compressed air energy storage (CAES), released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative. The objective of SI 2030 is to develop specific and quantifiable research, development. . Technology will be used to store wind and solar energy for use later.
