Design Code Analysis of Fire Protection Facilities in Hydrogen Refueling Stations

The Korean government has announced the construction of more than 310 hydrogen refueling stations by 2022 to establish a hydrogen infrastructure, which is crucial for realizing hydrogen economy. According to the fire act in Korea, most hydrogen refueling stations are not included in the specific structure for fire protection. Therefore, in this study, the fire protection facilities in hydrogen refueling stations and the amendment methods for those facilities were investigated using the Delphi method. A total of six fire protection facilities, including an automatic fire alarm system and sprinkler, were drawn. It is the conclusion of the paper, however the current fire act does not classified the hydrogen refueling station as the specific structure for fire protection. I think the following is better: Furthermore, hydrogen refueling stations needed to be included in the specific structure for fire protection by modifying the hydrogen storage tank volume. High-pressure gas act and relevant technical codes were further required to connect with fire regulations. Quantitative analysis of fire protection facilities and design codes for hydrogen refueling stations could provide information for the hydrogen infrastructure development.

Hydrogen Infrastructure Project Risks in The Netherlands

This study aims to assess the potential risks of setting up a hydrogen infrastructure in the Netherlands. An integrated risk assessment framework, capable of analyzing projects, identifying risks and comparing projects, is used to identify and analyze the main risks in the upcoming Dutch hydrogen infrastructure project. A time multiplier is added to the framework to develop parameters. The impact of the different risk categories provided by the integrated framework is calculated using the discounted cash flow (DCF) model. Despite resource risks having the highest impact, scope risks are shown to be the most prominent in the hydrogen infrastructure project. To present the DCF model results, a risk assessment matrix is constructed. Compared to the conventional Risk Assessment Matrix (RAM) used to present project risks, this matrix presents additional information in terms of the internal rate of return and risk specifics.
