Abstract

The social need for stable hydrogen storage technologies that respond to the increasing demand for hydrogen energy is increasing. Among them, underground hydrogen storage is recognized as the most economical and reasonable storage method because of its vast hydrogen storage capacity. In Korea, low-depth hydrogen storage using artificial protective structures is being considered. Further, establishing corresponding safety standards and ground stability evaluation is becoming essential. This study evaluated the hydro-mechanical behavior of the ground during a hydrogen gas leak from a low-depth underground hydrogen storage facility through the HM coupled analysis model. The predictive reliability of the simulation model was verified through benchmark experiments. A parameter study was performed using a meta- model to analyze the sensitivity of factors affecting the surface uplift caused by the upward infiltration of high-pressure hydrogen gas. Accordingly, it was confirmed that the elastic modulus of the ground was the largest. The simulation results are considered to be valuable primary data for evaluating the complex analysis of hydrogen gas explosions as well as hydrogen gas leaks in the future.

최근 증가하는 수소에너지 수요에 대응할 수 있는 안정적인 수소 저장 기술에 대한 사회적 니즈가 증가하고 있으며, 이 중 지중수소저장은 대규모 수소 저장이 가능하여 가장 경제적이고 합리적인 저장 방식으로 인식되고 있다. 국내의 경우, 인공적인 방호구조물을 활용한 저심도 수소 저장 방식을 고려하고 있는데, 이와 관련된 안전기준 확립 및 지반 안정성 평가가 중요해지고 있다. 본 연구에서는 저심도 지중 수소저장시설에서의 수소가스 누출 시 발생할 수 있는 지반의 수리역학적 거동을 복합해석 모델을 통해 평가하였다. 벤치마크 실험을 통하여 해석 모델의 예측 신뢰성을 검증한 후, 메타모델을 활용한 매개변수연구를 수행하여 고압수소가스의 지반 침투에 따른 지표면 융기현상에 대한 영향 인자들의 민감도에 대해 평가하였다. 분석결과, 수소가스의 지반누출에 따른 지표변위 변화에 대한 민감도는 지반의 탄성계수가 가장 큰 것으로 확인되었다. 이러한 연구결과는 향후 수소가스 누출뿐만 아니라 수소가스 폭발에 대한 지반 복합해석 평가 시 유용한 기초자료로 활용될 것이다.
