氢基础设施对于燃料电池汽车的商业化非常重要。氢的储存和运输是一个重要的课题，因为由于氢的危害，很难安全有效地处理大量的氢。一种利用与芳香族化合物的加氢和脱氢化学反应来保持和提供氢的有机化学氢化方法。该方法的优点是使用常规石油化工产品作为氢载体，而且石油化工产品比氢更容易处理，危害小。加氢站也是氢供应的重要基础设施。在日本，为了有效利用城市地区的空间，需要混合汽油氢燃料站。解决混合动力加气站的安全问题对于提高加气站的安全性至关重要。我们将重点放在了一个混合汽油-氢燃料站，该加油站配备了一个现场制氢系统，使用甲基环己烷作为有机化学氢化物。本研究的目的是通过危险识别研究（HAZID研究）揭示车站独特的混合风险。作为HAZID研究的结果，我们确定了314起涉及汽油和有机化学氢化物系统的事故。此外，针对独特的最坏事故情景，提出了改进的安全措施，以预防和减轻事故的发生。版权所有(C) 2016，氢能源出版有限责任公司由爱思唯尔有限公司出版版权所有。
Hydrogen infrastructures are important for the commercialization of fuel cell vehicles. Hydrogen storage and transportation are significant topics because it is difficult to safely and effectively treat large amounts of hydrogen because of hydrogen hazards. An organic chemical hydride method keeps and provides hydrogen using hydrogenation and dehydrogenation chemical reactions with aromatic compounds. This method has advantages in that the conventional petrochemical products are used as a hydrogen carrier, and petrochemicals are more easily treated than hydrogen because of low hazards. Hydrogen fueling stations are also crucial infrastructures for hydrogen supply. In Japan, hybrid gasoline hydrogen fueling stations are needed for effective space utilization in urban areas. It is essential to address the safety issues of hybrid fueling stations for inherently safer station construction. We focused on a hybrid gasoline-hydrogen fueling station with an on-site hydrogen production system using methylcyclohexane as an organic chemical hydride. The purpose of this study is to reveal unique hybrid risks in the station with a hazard identification study (HAZID study). As a result of the HAZID study, we identified 314 accident scenarios involving gasoline and organic chemical hydride systems. In addition, we suggested improvement safety measures for uniquely worst-case accident scenarios to prevent and mitigate the scenarios. Copyright (C) 2016, Hydrogen Energy Publications, LLC.
