Abstract

Research and development projects have been world widely carried out to develop the technology to produce gas from gas hydrate that have a high potential, as a future new energy. However commercial production is not achieved yet due to the technical problems and the high risks. In hydrate-bearing layer, it is required the technology to enhance gas recovery by dissociation, process to gasify gas hydrate that is solid state. The problems related to structure change or stability of sedimentary layer should be solved in this process. This study presents the possibilities of recovery and the value of future for gas hydrate as an energy resource by reviewing the commercial condition, methodology, and current state of development techniques. Especially, it has been presented the comparison of technological difference and the direction to progress the technology in Korea by investigating the international pilot production test.

미래의 신 에너지원으로서 높은 잠재력을 가지고 있는 가스하이드레이트의 개발 및 생산에 필요한 기술은 전 세계적으로 연구개발 중에 있으나 기술적 난제와 개발 위험성으로 인해 아직 상업적 목적의 산업화 단계까지는 도달되지 않은 상태이다. 가스하이드레이트층의 경우 고체상태인 하이드레이트를 기체화시키는 과정, 즉 해리를 촉진시켜 가스의 회수율을 높이는 기술이 요구되며 이 과정에서 퇴적층의 구조변화 혹은 안정성 문제가 해결되어야 한다. 본 연구에서는 가스하이드레이트의 상업적 생산조건 및 방법론, 생산 기술개발 현황을 고찰함으로써 에너지원으로서의 가스하이드레이트 생산 가능성 및 미래가치를 조망하였다. 특히 국제 공동 시험생산 프로젝트 추진현황 분석을 통해 국내 기술수준을 비교하고 향후 국내 가스하이드레이트 기술개발 방향을 제시하였다.
