In the ongoing debates over the need to identify new sources of energy and to reduce the emissions of greenhouse gases. Hydrogen has emerged as one of the most promising alternatives due to its emissions from the vehicle being virtually zero. The governments have identified the development of regulations and standards as one of the key requirements for commercialization of hydrogen-fueled vehicles. Regulations and standards will helpful in overcoming technological barriers to commercialization. Developments of a technique for safety assessment of Hydrogen Fuel Cell Vehicle(HFCV) includes four tasks, research for regulation system and policy, hydrogen safety, vehicle operation safety and protection against high-voltage. The objective is to establish a technique for safety assessment and amend safety standards for HFCV and consequently reflect research results to vehicle management policy. We devised safety standards and evaluation techniques with regard to high-pressure gas and high voltage of hydrogen fuel cell vehicle. Korean Motor Vehicle Safety Standards(KMVSS) for HFCV was amended to June 10, 2014. including the results of the safety assessment technology for high-voltage and hydrogen characteristics.

현재 정부의 「한국판 뉴딜 종합계획」발표('20.7.14, 관계부처 합동)에 따른 수소 생산 및 충전시설 보급 확대에 따라 주요 기업에서 액화수소 제조설비 건설계획 발표에 액화수소 플랜트, 충전소 등 관련시설 구축이 속도감 있게 진행되고 있다. 그러나 국내 액화수소 밸류체인에 따른 생산·저장시설·운송·활용 등에 대한 안전기준이 미흡한 실정이며, 액화수소 전주기에 걸친 안전 기술 및 안전기준 마련이 시급하다. 이에 한국가스안전공사는 액화수소 플랜트를 비롯한 전주기에 걸친 안전기준을 제·개정하고, 이를 통해 국내 안전한 수소 경제를 실현시키고자 한다.

Fuel cell powered unmanned aerial vehicles (UAV) are globally being developed for various application according to hydrogen roadmap. However, safety standards for hydrogen fuel cell for UAV have not been established. Therefore, in this study, we derive safety data based on risk assessment to develop safety standards for fuel cells for UAV. We use fault tree analysis method which is broadly used in hydrogen facilities as a risk assessment tool. We set hydrogen leaks and fires as top events and derived the basic events. Safety data for the basic events were derived by quoting overseas safety standards related to fuel cells. The safety data will be used for developing fuel cell inspection standard according to Act on Hydrogen Economy Promotion and Hydrogen Safety Management.

The governments have identified the development of regulations and standards as one of the key requirements for commercialization of HFCV. Regulations and standards will help overcome technological barriers to commercialization. The development of Global Technical Regulation (GTR) for HFCV occurred under the World Forum for Harmonization of Vehicle Regulations. Development of a technique for safety assessment of HFCV include four tasks, research for regulation system and policy, hydrogen safety, vehicle operation safety and protection against high-voltage. The objective is to establish a technique for safety assessment and amend safety standards for HFCV and consequently reflect research results to vehicle management policy.

정부의 수소 경제 활성화 로드맵에 따라 다양한 산업 분야에서 액화수소를 에너지원으로 하는 사업을 진행하고 있고, 액화수소 설비 및 취급시설의 제작 및 운영 실증 사업 또한 수행되고 있다. 그러나 운영 실증사업에 필요한 안전기준이 국내에는 마련되지 않아 실증 사업의 걸림돌로 작용하고 있어 조속한 안전기준 마련이 필요한 실정이다. 따라서 액화수소 설비 및 취급시설의 안전성 확보를 위하여 액화수소의 위험성을 종합적으로 고려한 안전기준의 마련이 반드시 필요하다고 본다. 본 연구에서는 일반적인 방법과 같이 국외사고 사례 분석 및 유사 분야의 안전기준을 참고로 도출한 선박용 액화수소 사용 시설 안전기준을 위험성 평가기법인 ETA, FMEA와 의사 결정방법인 AHP를 활용해 안전기준 항목의 우선순위 도출하여 안전기준 항목 선정에 타당성을 제시하고자 한다.

Korea is showing its appearance as a leading country in the hydrogen economy by establishing policies for revitalizing the hydrogen economy and enacting the 「Hydrogen Economy Promotion and Hydrogen Safety Management Act」 for the first time in the world. In addition, domestic hydrogen facilities are using hydrogen energy safely through world-class safety management compared to overseas advanced countries. However, in order to enhance the safety of the rapidly diversifying hydrogen industry and rapid technology development, such as the introduction of liquefied hydrogen, some institutional improvements are needed. In this regard, this paper intends to analyze the results of safety inspections on 13 representative facilities and prepare safety improvement plans to establish preemptive safety measures.

In order to expand the supply of hydrogen vehicles, the first thing to be done is to build an infrastructure to supply hydrogen. There are fixed and mobile types of hydrogen refueling stations that can supply hydrogen. Mobile hydrogen refueling stations have the advantage of supplying hydrogen to two or three areas, so the introduction of mobile hydrogen refueling stations is considered at the initial stage of hydrogen vehicle dissemination. However, mobile hydrogen refueling stations have greater risks than fixed hydrogen refueling stations due to the hazard associated with movement and intensive installation of facilities in vehicle, so stricter design standards to lower the risk must be applied. Therefore, in this study, basic data for establishing safety standards for mobile hydrogen refueling stations were proposed by suggesting improvements such as the location of emergency shutoff valves, the number of gas detectors etc., using HAZOP analysis.

일반적으로 수소의 정제는 화학적, 물리적인 방법을 통해 수행한다. 여러 종류의 정제방법 중 현재는 정제 용량 및 경제성이 가장 우수한 PSA(Pressure Swing Adsorption)를 이용한 정제방법이 가장 널리 사용되고 있다. 국내도 대부분 PSA를 이용하여 자동차 및 발전용 수소 연료전지 등에 사용하는 수소를 정제하고 있다. 기존 석유화학 단지중심의 부생수소는 운송 등의 어려움이 있다. 정부는 도시가스 공급망과 연계하여 소비지에서 직접 수소를 생산하는 수소추출기 설치 계획하고 있으며, 기업들도 이와 관련된 연구 및 실증 설비를 속속 설치하고 있는 실정이다. 유럽 등은 최근 PSA와 관련된 안전기준을 마련하여 시공 및 운영단계에서 체계적인 안전관리를 위한 노력을 기울이고 있으나, 국내는 PSA와 관련된 안전기준 마련이 아직까지는 미흡하다. 본 연구에서는 기존 PSA를 운영하고 있는 회사의 설문 및 위험성평가를 통해 기존설비의 문제점을 파악하고, 국외 기술기준에 이를 포함한 국내 기술기준을 작성하여 신규설치 및 기존 운영되고 있는 PSA시스템의 안전을 도모하고자 한다.

In July and October of this year, the government announced the 'Green new deal plan within the Korean new deal policy' and 'Strategies for proliferation of future vehicles and market preoccupation'. And, in response to changes in the global climate agreement, it has decided to expand green mobility such as electric vehicles and hydrogen electric vehicles with the aim of a "net-zero" society. Accordingly, the goal is to build 310 hydrogen refueling stations along with the supply of 60,000 hydrogen vehicles in 2022, and the hydrogen infrastructure is being expanded. however, it is difficult to secure hydrogen infrastructure due to expensive construction costs and difficulty the selection of a site. In Korea, it is possible to build a mobile hydrogen station according to the safety standards covering special case of the Ministry of Industry. Since the mobile hydrogen station can be charged while moving between authorized place, it has the advantage of being able to meet a large number of demands with only one hydrogen refueling station, so it is proposed as a model suitable for the early market of hydrogen infrastructure. This study demonstrates the establishment of a hydrogen refueling station by deriving a virtual accident scenario for leakage and catastrupture for each facility for the risk factors in a mobile hydrogen station, and performing a quantitative risk assessment through the derived scenario. Through the virtual accident scenario, direction of demonstration and implications for the construction of a mobile hydrogen refueling station were derived.
