Abstract
Currently, 787 hydrogen tube trailer are in operation as of the end of October 2022, and a maximum of 340 kg is transported in a Type 1 seamless container at a pressure of up to 200 bar. The current safety management system and facility management are in good condition, but the system and facility structure improvement are needed to strengthen safety. Accordingly, this paper simulated and analyzed an accident case that occurred on the Daejeon-Dangjin highway on December 28, 2021 during the process of expanding the supply and operation of hydrogen tube trailer according to the hydrogen energy activation policy. Based on the results, suggestions were made on how to improve the safety of hydrogen tube trailer.
