Korea has proposed two new hydrogen technologies as international standards at the ISO/TC197 General Assembly held in Seoul. These technologies focus on water electrolysis performance evaluation and high-pressure hose testing for hydrogen tube trailers. The proposals were well-received by member countries, highlighting Korea's advancements in hydrogen technology. The detailed approach in the performance evaluation test method for water electrolysis aims to enhance precision by subdividing technology development units. Similarly, the high-pressure hose test method for hydrogen tube trailers targets safe and efficient hydrogen transportation through rapid intake. Korea's active participation in setting international standards reflects its dedication to innovation and leadership in the global hydrogen market. By aiming to facilitate the adoption of its technologies worldwide, Korea seeks to gain a competitive edge in the burgeoning hydrogen economy. The government's support for standard development underscores its strategic vision to lead in hydrogen technology and capitalize on the projected $12 trillion global market by 2050. The successful standardization of these technologies could not only boost Korea's economic growth but also contribute to the global transition towards clean energy, emphasizing the importance of hydrogen in achieving carbon neutrality and energy security.
