초록

There are various types of hydrogen production methods, but among them, the alkaline water electrolysis method produces hydrogen by electrolyzing water, and unlike other methods, it can produce green hydrogen that does not emit pollutants and greenhouse gases. There are many different potential risk factors inherent in the water electrolysis process. So it is necessary to predict an emergency situation in advance and to safely manage and take countermeasures according to the emergency situation. Korea Gas Safety Corporation (KGS) CODE AH271 stipulates legal matters to secure safety, but it is not detalied. Thus it is necessary to take measures to safely control and manage it according to the situation in which an emergency stop is required. In this study, based on KGS CODE and HAZOP for alkaline water electrolysis facilities, factors that can cause emergency situations were derived and countermeasures were prepared.
