초록

최근 수소충전소 수요 증가에 따라, 산업통상자원부는 LPG, CNG, 주유소 등 기존의 자동차용 연료공급시설 내에 융합, 복합의 형태로 수소충전소 설치가 가능하도록 특례고시를 제정·공포하였다. 수소 융복합충전소는 특례기준 제정 이전까지 국내에서 운영된 사례가 없어, 4계절, 일교차와 같은 환경특성을 감안한 실증이 필요하다. 본 연구에서는, 국내 최초로 실증을 위해 설치된 울산 LPG-수소복합충전소의 충전데이터를 수집하여 분석하였다. 충전데이터는 압축기, 저장용기, 디스펜서에서 발생한 시간별 온도, 압력 데이터이며, 계절별 특성을 비교하기 위해 2018년 7월 중 울산 지역의 최고기온 일과 2018년 1월 중 최저기온 일을 포함하여 4계절 충전데이터를 수집하여 비교하였다. 비교결과, 외기온도의 변화가 수소차 차량용기의 초기온도에 영향을 미치는 것으로 나타났으며, 이는 최종적으로 차량의 충전시간과 충전속도에도 영향을 미치는 것으로 나타났다. 국내 수소충전소 기준(KGS FP217)과 미국의 충전프로토콜(SAE J2601)에서 제시한 한계온도를 초과한 경우는 없어 차량용기에 대한 영향은 없는 것으로 나타났다.

In response to the recent increase in demand for hydrogen stations, the Ministry of Trade and Industry has enacted and promulgated special notifications to enable the installation of hydrogen stations in the form of the combined complex in existing automotive fuel supply facilities such as LPG, CNG, and gas stations. Hydrogen multi energy filling stations haven't been operated yet in Korea till the establishment of special standards, so it is necessary create special standards by considering all Korean environmental characteristics such as four seasons and daily crossings. In this study, we collected and analyzed the charging data of Ulsan LPG-Hydrogen Multi Fueling Station installed for the first time in Korea. The data are hourly temperature and pressure data from compressors, storage vessels and dispensers. We used the data collected for a year, including the highest temperature and the lowest temperature in Ulsan to compare seasonal characteristics. As a result, it was found that the change of the outside temperature affects the initial temperature of the vehicle's container of the hydrogen car, which finally affects the charging time and the charging speed of the vehicle. There was no effect on vehicle containers because the limit temperature suggested by the Korean Hydrogen Station Standard(KGS FP217) and the US Filling Protocol(SAE J2601) was not exceeded.
