Abstract

The importance of renewable energy has increased continuously due to the energy insecurity and the necessity of reducing carbon dioxide which is causing global climate change. In such a situation, the Pohang Enhanced Geothermal System (EGS) power plant project which is launched in December 2010 shall be a new opportunity for the development of EGS related technologies in Korea. In this paper, the case studies of Fenton Hill project in the USA and Hijiori project in Japan are introduced in order to help a part of the domestic EGS demonstration project. As a result, it could be helpful to minimize the trial and error of the domestic EGS project by acquiring the achievements and limitations of existing EGS projects.

최근 전 세계적으로 에너지 수급의 불안정 및 기후변화에 의한 이산화탄소 저감의 필요성으로 인하여 신재생에너지에 대한 중요성은 점차 증가하고 있다. 이러한 상황에서 지난 2010년 12월에 시작되어 진행 중인 한국 최초의 포항 인공지열 저류층 생성 기술 (Enhanced Geothermal System; EGS) 지열발전소 프로젝트는 국내 EGS 관련기술 발전에 새로운 계기가 될 것이다. 본 논문은 국내 EGS 실증사업에 일부분이라도 도움이 되고자 미국 Fenton Hill 및 일본 Hijiori 프로젝트 연구사례를 살펴보고, 이를 통해 기존 EGS 프로젝트의 성과와 한계를 습득함으로써 국내 EGS 프로젝트의 시행착오를 최소화하는데 도움이 되고자 한다.
