Le principal intérêt du stockage par air comprimé consiste aujourd’hui à réaliser cette compression en utilisant de l’électricité disponible à un prix faible qui serait potentiellement « fatale », c'est-à-dire perdue si elle n’était pas utilisé à cette fin. Le premier avantage d’un CAES est purement économique.
En phase de déstockage, l’air comprimé est extrait de son réservoir et envoyé dans la chambre de combustion qui précède la turbine. L’énergie produite est enfin restituée ou vendue au réseau.
L’air chaud comprimé est injecté avec du gaz dans une chambre de combustion. Le mélange en sortie entraîne une turbine et un alternateur pour produire de l’électricité. Le principe du CAES consiste à stocker l’air comprimé et ainsi à décorréler la phase de compression de l’air du reste du processus.
Lorsque l’on veut récupérer cette énergie potentielle, l’air comprimé est déchargé dans une turbine qui entraînera un alternateur. Cette étape nécessite un combustible pour détendre l’air (généralement du gaz naturel).
Il ne faut donc pas attendre la compression de l'air pour extraire la chaleur. Cela doit se faire au fur et à mesure pour en conserver un maximum. Grâce à cette technique un rendement de 95% (le double des CAES actuels) serait envisageable. Le stockage de chaleur reste malgré cela un challenge en soi...
