Compressed Air Energy Storage (CAES) systems offer a promising approach to addressing the intermittency of renewable energy sources by utilising excess electrical power to compress air that is stored under high pressure. . 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. At a utility scale, energy generated during periods of low demand can be released during peak load periods. When energy demand peaks, this stored air is expanded through turbines to. .

CAES operates by using surplus electricity to compress air, which is stored in underground caverns, salt caverns, or tanks. The process is often integrated with natural gas to improve efficiency, especially during the release phase. 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. This overview explains the concept and purpose of CAES, providing a comprehensive guide through its step-by-step process of. . Compressed Air Energy Storage (CAES) has emerged as one of the most promising large-scale energy storage technologies for balancing electricity supply and demand in modern power grids.
