SEOUL — September 28, 2022 — Nylon has evolved into the core material of the hydrogen energy industry.
Hyosung TNC announced on the September 7 that it has succeeded in developing and using nylon for the liner material of hydrogen vehicle fuel tanks with its own technology, the first of its kind for a Korea-based company.
A liner is a core component required to store hydrogen in the fuel tank’s internal container and prevent leakage.
Hyosung TNC’s nylon material is superior to conventional metal and high-density polyethylene (HDPE) liner materials in terms of lightweight, gas barrier, and impact resistance.
Superior light and safe than metal… Excellent impact resistance against temperature fluctuation
The nylon liner material developed by Hyosung TNC is 70-percent lighter than metal and 50-percent lighter than HDPE and gas barrier property that prevents leakage of hydrogen gas is also 30-percent higher than metal and 50-percent higher than HDPE.
Metal liner is heavy and has a high risk of brittleness when exposed to hydrogen for a long period of time, whereas nylon liner has low hydrogen absorption and air permeability, so there is no risk of being brittleness.
HDPE liners are used as high-pressure containers at 400bar levels, but cannot withstand the 700bar pressure required by typical hydrogen electric vehicles.
In addition, the hydrogen container liner must be able to withstand rapidly changing temperature fluctuation caused by frequent charging and discharging of hydrogen and the nylon liner has excellent impact resistance against to it from -40 to 85 degrees Celsius.
Expected the import effect of 270 billion won annually by 2030
The success of this development is significant in that it has laid the foundation for Hyosung TNC to enter the nylon liner market, which has been monopolized by foreign companies, for the first time as a domestic company.
According to H2 Research, a research institute specializing in the hydrogen market, the global hydrogen vehicle market will grow in earnest, including restrictions on the operation of internal combustion engine trucks in major urban areas in Europe from 2025 is expected to expand to 1.05 million units.
Therefore, the import substitution effect of the nylon material liner market is expected to grow to about 270 billion won annually in 2030.
In addition, with the expansion of various hydrogen mobility markets such as hydrogen electric vehicles, drones, trams, ships, and UAM (urban air mobility), nylon is expected to gain more attention as a liner material for hydrogen containers.
The complete of Hydrogen Value Chain in Production, Distribution, Storage and Utilization
The nylon liner is expected to contribute to the completion of Hyosung’s hydrogen value chain.
Hyosung has built a hydrogen value chain through No. 1 supplier of hydrogen charging stations in Korea, construction of liquefied hydrogen plants and liquefied hydrogen filling stations that will change the map of the hydrogen economy, production of carbon fiber, which is essential for fuel tanks for hydrogen vehicles, etc.
The success of this development is significant because Hyosung has secured the technological capabilities to lead the global market not only in the production and distribution of hydrogen but also in the storage and utilization fields.
Chairman Cho Hyun-Joon said, “Fiber evolves into a key energy material by combining to technology”
Hyosung TNC’s nylon-applied hydrogen container passed the hydrogen container international quality standard (UN/ECE R134) in June, and has been equipped with function, quality and technical perfection as a liner material. It is also planned to conduct commercial tests in cooperation with hydrogen fuel tank manufacturers and automakers.
Hyosung TNC is planning to expand the application of nylon as a liner material from tube trailers of commercial trucks to CNG and hydrogen vessels sailing the seas around the world, such as Antarctica and the Equator, by enhancing the impact and heat resistance range from -60 to 90 degrees Celsius.
In addition, as Hyosung TNC developed the world’s first recycled nylon fiber technology from recycled fishing nets discarded in the sea, it plans to expand the eco-friendly plastic material market by applying recycled nylon to a liner material in the future.
Chairman Cho Hyun-Joon added: “Hyosung TNC’s development of nylon liner material demonstrates, even in the textile industry, which has been regarded as a declining industry, the innovation that transforms it into a key material for the high-tech hydrogen industry, can happen if it’s supported by technology. We will contribute to the development of the future eco-friendly energy industry with the technology of materials and textiles.”
