  • Compressed-air-storing electricity generating system and electricity generating method using the same
    Patent number: 7663255
    Abstract: Disclosed are a compressed air energy-storing electricity generating system and an electricity generating method using the same, in which air of a high pressure is injected into a tank laid under the ground using midnight electricity and surplus produced electricity, and the air of the high pressure in the tank is uniformly discharged so as to drive a generator during a time period when the consumption of electric power is high, thus efficiently managing energy.
    Type: Grant
    Filed: August 16, 2007
    Date of Patent: February 16, 2010
    Assignee: Korea Institute of Machinery & Materials
    Inventors: Yeong-min Kim, Daniel Favrat, Dong-gil Sin, Kyu-baek Cho
