Collaboration with Korea Gas Technology Corporation
Completion of reliability test... full-fledged commercialization
Promotion of trial application in 3~5 places in January
This new year, an industry tape specialty company, Daehyun ST, applies hydrogen leak detection tape to hydrogen charging stations. It completes the hydrogen leak detection tape reliability test, and begins commercialization in collaboration with Korea Gas Technology Corporation.
Daehyun ST will test-apply the hydrogen leak detection tape to 3 to 5 hydrogen charging stations nationwide from January. It is the first time that Daehyun ST supplies hydrogen leak detection tape to hydrogen charging stations.It has succeeded in localizing key materials for creating an ecosystem in the domestic hydrogen safety field.
Daehyun ST received technology transfer from Ajou University’s Professor Hyungtak Seo’s team last yearto commercialize the discoloration tape for detecting hydrogen leakage.
When the tape-shaped material comes into contact with hydrogen gas, it can be checked for leakage by changing the color. It is a principle of detecting color change by using plasmonic phenomenon that occurs when hydrogen and oxide are bonded by diffusing hydrogen molecules separated by a catalytic material into an oxide thin film. It can be easily identified with eyes, and quickly detects the leakage of hydrogen.
Daehyun ST applied the first test to a hydrogen compressor in the Daejeon Hydrogen Product Safty &Test Center of Gas Technology Corporation, and conducted a field test in June. The hydrogen Industry overall life cycle center is an institution that tests and evaluates the performance and durability of various hydrogen products, such as hydrogen extraction technology and water electrolysis including hydrogen filling valves, compressors, and hoses. Daehyun ST hydrogen checked the color change at vulnerable fields in the process of discoloration tape samples for hydrogen leakage, and took action in safety measures.
Daehyun ST and hydrogen industry overall life cycle Center conducted field evaluations at the first hydrogen charging station to improve product performance and verify reliability. The demonstration project was conducted for two months from August, and selected as an excellent performance by Korea Gas Technology Corporation by proving the product technology and business feasibility.
It is expected in the future for additional applications in hydrogen charging stations. It is expected to be applied nationwide if the reliability of the hydrogen discoloration tape is proven. The company will continue to cooperate with the hydrogen industry overall life cycle Center.
Daehyun ST is also developing the discoloration tape that can be checked with the naked eye as well as a hydrogen leak detection solution using an electronic sensor It is researching and developing (R&D) a method that automatically warns when the tape is discolored using a camera and a broadband hydrogen detection sensor. The method can be applied in various fields such as hydrogen pipelines, storage devices, fuel cell hydrogen infrastructure, and semiconductor hydrogen processes that it can detect broadband hydrogen detection sensor from a low concentration of 0.01% to a high concentration of 100%. Daehyun ST plans to mass produce with R&D and facility investment in early 2024.
Jooheung Eom, CEO of Daehyeon ST, said, “It is important to collaborate with Korea Gas Technology Corporation's Hydrogen Industry overall Life cycle Center, and we will continue to work together to standardize products for the first time in the world."
Heeseung Na, head of the hydrogen industry overall life cycle Center at Gas Technology Corporation, said, “We will cooperate with Daehyun ST in establishing standardization, and apply the product for the purpose of enhancing safety in various charging stations and other hydrogen fields by using Daehyun ST’s hydrogen discoloration tape sensor.
