Abstract

The development of a smart city emphasizes the need for sustainable energy supply and management, with hydrogen energy emerging as a key alternative. This paper reviews the necessity and explosion characteristics of hydrogen energy to enhance energy transition and safety within smart cities. Hydrogen, recognized as an environmentally friendly energy source due to its high energy density and zero carbon emissions, presents significant safety challenges due to its low ignition energy and high explosiveness. The study reviews the mechanisms of hydrogen explosions (deflagration and detonation) and explores methods to mitigate explosion risks through protective structural design and computational fluid dynamics (CFD) analysis. Additionally, the potential of AI-based predictive systems in enhancing hydrogen energy safety is addressed. Hydrogen energy is a vital resource for the sustainable development of smart cities, but effective management of explosion risks requires technological advancements and policy support.

스마트시티의 발전은 지속 가능한 에너지 공급과 관리의 필요성을 강조하며, 수소에너지가 핵심적인 대안으로 부상하고 있다. 본 리뷰논문은 스마트시티 내 에너지 전환과 안전성을 강화하기 위해 수소에너지의 필요성과 폭발 특성을 검토한다. 수소는 높은 에너지 밀도와 무탄소 배출 특성으로 친환경 에너지원으로 인정받고 있지만, 낮은 점화 에너지와 높은 폭발성으로 인해 중대한 안전 문제를 제기한다. 본 연구는 수소 폭발의 메커니즘(폭연과 폭굉)을 리뷰하고, 방호 구조물 설계 및 전산유체역학(CFD) 분석을 통해 폭발 위험을 완화하는 방법을 탐구한다. 또한, 인공지능(AI) 기반 예측 시스템이 수소 에너지 안전성을 향상시키는 데 기여할 가능성을 리뷰하였다. 수소 에너지는 스마트시티의 지속 가능한 발전을 위한 중요한 자원이지만, 폭발 위험을 효과적으로 관리하기 위해서는 기술적 진보와 정책적 지원이 필요하다.
