<p>The present invention relates to a system and a method for storing and recovering electric energy using compressed gas. The system for storing and recovering energy according to the present invention comprises: a gas storing container (110) which can store compressed gas; an open type fluid storage tank (120) which can store fluid; hydraulic/pneumatic pressure converting units (130) respectively connected to the gas storing container and the fluid storage tank to convert applied hydraulic pressure into pneumatic pressure or convert applied pneumatic pressure into hydraulic pressure; an electric compressor (140) mounted between the gas storing container (110) and the hydraulic/pneumatic pressure converting units (130) to generate compressed air; and a valve (150) for controlling a flow of the compressed gas transferred to the gas storing container (110), thereby effectively storing and recovering electric energy and being utilized in various ways as middle-sized and small-sized distributed generation systems because the above processes are carried out in distribution.</p> |
