The recovery of low temperature geothermal energy （40∼80 ℃） in Korea is investigated by injecting air seasonally for local community heating without heat exchangers, when a gas storage development is planned. A preliminary design was conducted to study the feasibility of the scheme. Safety, economics, reserve estimation, and aquifer dynamics were studied. Other recovery methods and power generation have been briefly reviewed. Conversion to a small gas storage system upon depletion of geothermal energy, because of the Korea's pressing need for underground storage system and the overall economic advantage, plays a very significant role to make the energy recovery attractive.
