비생물기원 수소 생산성의 지질학적 평가 관련 해외 연구 동향: 리뷰 논문 = Research Trends of Foreign Countries on Geological Evaluation of Abiotic Hydrogen Productivity: A Review

다국어 초록 (Multilingual Abstract)

The world’s long reliance on fossil fuels (e.g., oil, coal, and natural gas) is severely changing its environment and climate. Energy research has focused on developing hydrogen as the most promising energy carrier and a key technology for sustainable energy development. Hydrogen can be classified as gray, blue, green, and otherwise according to the raw materials and methods used for production and processing. For the development of hydrogen energy, geologists are attempting to identify the mechanism of abiotic hydrogen generation by serpentinization or hydrothermal alteration. Teams in the United States, France, and Australia have researched laboratory-scale hydrogen production through water-rock interactions under various conditions, whereas there has been almost no research on abiotic hydrogen in South Korea. This paper reviews the current state of international research on hydrothermal alteration and offers suggestions for future investigations of abiotic hydrogen production in South Korea.

국문 초록 (Abstract)

최근까지 전 세계 에너지 수요는 화석연료(석유, 석탄, 천연가스)에 의존해왔으며, 이로 인해 지구온난화와 같은 심각한 전 지구적 환경 변화를 유발하고 있다. 에너지 관련 분야의 연구자들은 가장 유망한 에너지 운반체이자 지속 가능한 에너지 개발의 핵심 기술인 수소 에너지에 주목하고 있다. 수소 연료는 생산을 위해 사용되는 연료와 공정처리과정에 따라 그레이수소, 블루수소, 그린수소 등으로 분류된다. 지질학자들은 수소 에너지 개발을 위해 사문암화작용 또는 열수변질작용에 의한 비생물기원 수소 생산메커니즘 규명 연구를 진행하고 있다. 특히, 미국, 호주, 프랑스 등의 국가에서는 실내실험 규모의 물-암석 반응 실험을 통해 다양한 조건에서의 수소생산성을 연구하였으나, 국내에서는 비생물기원 수소에 대한 연구가 거의 진행된 바 없는 실정이다. 이에 본 리뷰에서는 비생물기원 수소 생산을 위해 물-암석 반응 실험을 진행한 해외 연구 사례의 현황을 파악하고 향후 국내 비생물기원 수소 생산 실험을 위한 발전방향을 제시하였다.
