초록

지열에너지는 기저부하를 제공하는 신재생에너지이나 현재까지 화산지대에만 대부분의 지열발전이 이루어져 왔다. 인공저류층 지열시스템 (Enhanced Geothermal System, EGS)는 비화산지대의 지열발전을 가능하게할 개념으로 알려져 있으며 수리자극(hydraulic stimulation)이 핵심기술이다. 본 논문은 EGS지열발전의 개발 현황을 소개하고, 수압파쇄와 수리전단이 주 메커니즘인 수리자극의 핵심원리, 설계변수 및 수리자극에 수반되어발생하는 미소진동의 원리 및 관측기술을 소개한다. 한국에서의 EGS 지열발전을 위하여 필요한 과제를 소개하여 향후 기술개발의 방향을 제시한다.

Abstract

While geothermal energy provides the only base-load power among renewable energy sources, its development has been carried out predominantly in volcanic area. EGS (Enhanced Geothermal System) is a ubiquitous technology that can allow the geothermal power generation virtually in any area. This manuscript introduces the current state-of-the-art of EGS development in the world and presents the hydraulic stimulation technology and associated microseismicity which are key technical component in EGS. Finally this paper suggests the key research areas required in Korea for further development of EGS.
