Compressed Air Energy Storage: Types, systems and applications

Compressed air energy storage (CAES) uses excess electricity, particularly from wind farms, to compress air. Re-expansion of the air then drives machinery to recoup the electric power. Prototypes have capacities of several hundred MW. Challenges lie in conserving the thermal energy associated with compressing air and leakage of that heat

OverviewTypesCompressors and expandersStorageEnvironmental ImpactHistoryProjectsStorage thermodynamics

Compressed-air-energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational as of 2024 . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity
