수소저장기술은 수소경제를 달성하기 위해 개발해야할 핵심요소기술이다. 이 논문에서는 고체수소저장기술의 최신 개발 동향을 고찰하였다. 나노구조 탄소계 물질(nanostructured carbon materials), 유기금속구조물(metal organic framework, MOFs), 금속수소화물(metal hydrides), 클래스레이트수화물(clathrate hydrates), 금속착수소화물(complex chemical hydrides)과 같은 고체수소저장매체를 중점적으로 고찰하였다. 그 결과 지금까지 개발된 고체수소저장재료의 수소저장용량은 고체의 표면적에 비례하여 증가함을 알 수 있었다. 또한 수송용 탑재형 수소저장 응용을 목적으로 안전하면서도 가역적 고밀도 수소저장이 가능한 기능성 신 나노재료의 개발 방향을 제시하였다.
This article provides a panoramic overview of the state-of-the-art technologies in the field of solid-state hydrogen storage method. The emerging solid-state hydrogen storage techniques, such as nanostructured carbon materials, metal organic framework (MOFs), metal and inter-metal hydrides, clathrate hydrates, complex chemical hydride are discussed. The hydrogen storage capacity of the solid-sate hydrogen storage materials increases in proportion ot the surface area of the solid materials. Also, it is believed that new functional nanostructured materials will offer far-reaching solutions to the development of on-board hydrogen storage system for the application of the transportation vehicles.
