Compressed Air Energy Storage (CAES) is one of the promising methods to store the surplus solar and wind energy in a grid scale. In this study, we used a non-isothermal multiphase flow simulator to model a field-scale study of a novel CAES by storing the compressed air in aquifer. The primary results show that the model is capability of modeling dynamics of pressure induced by air injection rates. The model was successful to model the well head pressure changes during the bubble development stage. This study suggests that further works shall be carried out to validate the model by simulating the injection-withdrawal cycle’s experiments, as well as to investigate key factors affecting storage and thermal efficiency of compressed air in porous rock reservoirs.
