Abstract

Hydrogen is a renewable energy source with various characteristics such as clean, carbon-free and high-energy, and is internationally recognized as a "future energy". With the rapid development of the hydrogen energy industry, more hydrogen infrastructure is needed to meet the demand for hydrogen. However, hydrogen infrastructure accidents have been occurring frequently, hindering the development of the hydrogen industry. HyRAM+, developed by Sandia National Laboratories, is a software toolkit that integrates data and methods related to hydrogen safety assessments for various storage applications, including hydrogen refueling stations. HyRAM+'s physics mode simulates hydrogen leak results depending on the hydrogen refueling station components, graphing gas plume dispersion, jet frame temperature and trajectory, and radiative heat flux. In this paper, hydrogen leakage data was extracted from a hydrogen refueling station in Samcheok, Gangwon-do, using HyRAM+ software. A hydrogen leakage simulator was developed using data extracted from HyRAM+. It was implemented as a dashboard that shows the data generated by the simulator using a database and Grafana.

수소는 청정, 무탄소, 고에너지등 다양한 특징을 가진 재생에너지원으로 국제적으로 '미래에너지'로 인정받고 있다. 수소에너지 산업의 급속한 발전과 더불어 수소 수요를 충족시키기 위하여 더 많은 수소 인프라가 필요한 실정이다. 그러나 수소 인프라 사고가 빈번한 발생함으로 인해, 수소산업 발전에 걸림돌이 되고 있다. 미국 Sandia National Laboratories에서 개발한 HyRAM+는 수소충전소를 포함한 다양한 저장 응용 분야에 대한 수소 안전 평가와 관련된 데이터와 방법을 통합하는 소프트웨어 툴킷이다. HyRAM+의 물리 모드는 수소충전소 컴포넌트에 따라 수소누출 결과를 모사하여 가스 플룸 분산, 제트 프레임 온도와 궤적 그리고 복사 열속 등을 그래프로 나타낸다. 본 논문에서는 강원도 삼척시에 있는 수소충전소를 대상으로하여 HyRAM+ 소프트웨어를 이용하여 수소 누출 데이터를 추출하였다. HyRAM+에서 추출한 데이터를 이용하여 수소 누출(Leakage) 발생 시뮬레이터를 개발하였다. 데이터베이스와 그라파나(Grafana)를 이용하여 시뮬레이터에서 발생한 데이터를 보여주는 대쉬보드(Dashboard)로 구현하였다.
