A hydrogen charging station was installed in Nam-gu, Ulsan, to supply hydrogen through pipes. Related infrastructures are being built in Ulsan, which aims to become a’hydrogen economy mecca city’.
Ulsan City announced on the 30th that it had completed the’Together Hydrogen Charging Station’ in the area around 101 in Shinhwa-ro, Nam-gu. This charging station, which started construction in February last year, is the first station in the country to supply hydrogen through piping. The hourly filling scale is 55 kg. It has the facility capacity to charge more than 130 units a day. Existing charging stations could charge about 50 units a day.
The city of Ulsan explained that the hydrogen supply method through supply pipes in the city center is the third in the world after Japan and the United States. Compared to supplying hydrogen as a vehicle (tube trailer), it is possible to move large quantities of water, increasing the capacity of charging stations, as well as reducing transportation costs and preventing accidents caused by large vehicles.
Ulsan City plans to build a north-south axis from Onsan National Industrial Complex through Taehwagang Station to the Gyeongju border in Gyeongsangbuk-do to supply hydrogen to transportation, industrial and residential complexes, and expand hydrogen pipeline networks to the western and eastern regions.
A sensor based on information and communication technology (ICT) was applied to the hydrogen charging station and the upper part of the hydrogen pipe. It has built a safety management system that citizens can trust and use through real-time monitoring through optical fibers and sensors.
The hydrogen charging station in the Deokha Public Garage, completed on this day, is a bus-only charging station. Hydrogen buses require more than 5 times more hydrogen than hydrogen cars and have a long waiting time after charging. Because of this, the inconvenience of hydrogen passenger car operators that occurred when charging hydrogen buses at general hydrogen charging stations is expected to be reduced. The city expects that it will help expand the supply of various hydrogen mobility by processing even large commercial vehicles. There are eight charging stations for hydrogen electric vehicles in Ulsan. Ulsan City is planning to build four additional charging stations in the western, northern, eastern and southern regions by next year to increase accessibility throughout Ulsan. The city plans to build a hydrogen mega station that can charge various hydrogen mobility such as large buses, hydrogen trucks, construction equipment, and hydrogen trams around Taehwagang Station after next year.
Ulsan Mayor Song Chul-ho said, “We plan to show the world’s best hydrogen city in 2030 by first expanding the hydrogen pipeline, building a hydrogen housing model, and applying a precision monitoring safety management system.”
