"Eco-friendly" automobile has been a symbol of the Low Carbon, Green Growth strategy that Korea government decided to pursue. In line with the recent policy trend, a number of new LPG stations are being constructed. However, communities where mass storage are installed have been suffered from risk of serious accidents. In this work, economic analyses for different installation methods has been performed to prevent accidents in LPG filling station. The review shows that the underground storage is beneficial for the maintenance and the effective land use.

Hydrogen emerged as a sustainable transport energy source. To increase hydrogen utilization, hydrogen refueling stations must be available in many places. However, this requires large-scale financial investment. This paper proposed a methodology for selecting the optimal location to maximize the use of hydrogen charging stations. The location of gas stations and natural gas charging stations, which are competing energy sources, was first considered, and the expected charging demand of hydrogen cars was calculated by further reflecting data such as population, number of registered vehicles, etc. Using k-medoids clustering, one of the machine learning techniques, the optimal location of hydrogen charging stations to meet demand was calculated. The applicability of the proposed method was illustrated in a numerical case of Seoul. Data-based methods, such as this methodology, could contribute to constructing efficient hydrogen economic systems by increasing the speed of hydrogen distribution in the future.

Recently, the world's countries are tightening regulations on CO2 and air pollutants emission to solve them. In addition, eco friendly vehicles is increasing to replace automobiles in internal combustion engine. The government is supporting the expansion of hydrogen refueling infrastructure according to the hydrogen economy road map. In particular, refueling station is important to secure the safety that supplies high-pressure hydrogen with a wide LFL range. This paper is on guidelines for the determination safety distances to ensure worker safety from accident as jet fire. The safety distance is set according to the procedure of the EIGA doc 075/21. For accident frequency is upper 3.5E-05 per annum, safety distance is decided via consequence analysis where the risk of harm is below individual harm exposure threshold.

본 연구에서는 수소 경제의 핵심 인프라 시설인 수소 충전소의 조업자 안전 운전을 위한 교육 및 훈련 프로그램을 구축하였으며, 개발된 프로그램은 크게 수소안전교육 모듈, 수소 충전소 가상체험 모듈, 가상 사고 시나리오 모듈로 구성되어 있다. 수소안전교육 모듈에서는 수소 사고의 특징과 안전 물성 등의 자료를 수록함으로써 수소에 안전에 대한 이해를 돕도록 하였으며, 가상체험 모듈에서는 충전소의 구성과 용도를 3D Virtual Reality 기술을 도입해 간접 체험할 수 있도록 하였다. 또한 가상사고 모듈에서는 수소 충전소에서 일어날 수 있는 사고에 대한 동적 모사를 수행하여 사고의 전개 과정 및 결과를 체험해 볼 수 있도록 하였다. 이와 함께 사고가 일어났을 경우 신속하고 정확한 대응을 통해 피해를 최소화하기 위한 ERP(Emergency Response Plan)과 SOP(Standard Operating Procedure)를 개발하였다.

Fundamental Electric vehicle charge system is urgently needed for commercialization of electric vehicles. Car parking building is equipped with PV system for providing electricity to charge electric vehicles, because it must be charged at least for 30 minutes. In parking lots abroad, electric car charging stations are installed to charge electric cars by the electricity gained from PV systems which are also installed. Also, charge infrastructure construction plans and electric car charging facility support standards are being set and proposed, but there are no cases like abroad of electric car charging stations using PV systems and only electric car charging stations using ordinary electricity are being proposed. Therefore, this paper prepares establishment of domestic electric car charging networks. By researching inside outside solar parking lots and cases of abroad PV system electric car charging stations, and by analysis and comparative analysis of structural systems, structural material, and etc., many cantilever structure and small-size types were installed in PV system electric car charging stations.

A safety assessment was performed through the process analysis of hydrogen station. The purpose of this study provides basic information for the standard establishment about hydrogen stations. The processes of hydrogen stations were classified by four steps (process of manufacture, compression, storage, charge). FMEA (Failure Mode and Effect Analysis) method was applied to evaluate safety. Each risk element is following; S (severity), O (occurrence), D (detection). And the priority of order was decided by using RPN (Risk Priority Number) value multiplying three factors. Scenarios were generated based on FMEA results. And consequence analysis was practiced using PHAST program. In the result of C.A, jet fire and explosion were shown as accident types. In case of leakage of feed line in PSA process, concentration of CO gas is considered to prevent CO gas poisoning when the raw material that can product CO gas was used.

The concern of Global warming and greenhouse gas emission has been issuing so many countries are trying to establish environmental friendly logistics policies. With this trend, several technical and operational methods are developed to realize green logistics way. In Korea, government promoted converting LNG cargo vehicles and constructed LNG station at Dajeon, Pohang, Gwangyang, Incheon, and Donghae as a national project. In spite of economic and environmental advantages, this project was not successful enough, even the project was cancelled. So, this paper seeks the reason why the project was failed and find if there were enough capacity and numbers of LNG stations, then analyze the problem.
