Le « CAES », (de l''anglais Compressed Air Energy Storage) est un mode de stockage d''énergie par air comprimé, c''est-à-dire d''énergie mécanique potentielle, qui se greffe sur des turbines à gaz.. Comment ça marche ? Dans une turbine à gaz classique, de l''air ambiant est capté et comprimé dans un compresseur à très haute pression (100 à 300 bar).
The application of elastic energy storage in the form of compressed air storage for feeding gas turbines has long been proposed for power utilities; a compressed air storage system with an underground air storage cavern was patented by Stal Laval in 1949. Since that time, only two commercial plants have been commissioned; Huntorf CAES, Germany, and
Compressed Air Energy Storage (CAES) offers potential, but faces challenges including poor efficiency and reliance on fossil fuels.
