晓星TNC (KRX:298020) 7日宣布，韩国公司首次利用自主技术成功开发并使用尼龙作为氢燃料储罐的内衬材料。

Hyosung: Newly Transformative Nylon, As Core Material for Hydrogen Energy

衬里是在燃料箱的内部容器中储存氢气并防止泄漏所需的核心部件。

晓星 的尼龙材料在重量轻、阻气性和抗冲击性方面优于传统的金属和高密度聚乙烯 (HDPE) 衬里材料。

 

比金属更轻、更安全……对温度波动具有出色的抗冲击性

晓星开发的尼龙衬里材料比金属轻70%，比HDPE轻50%，防止氢气泄漏的阻气性也比金属高30%，比HDPE高50%。

金属内胆较重，长时间接触氢气易脆化，而尼龙内胆吸氢性和透气性低，不存在脆化风险。

HDPE 内衬用作 40MPa水平的高压容器，但无法承受典型氢电动汽车所需的 70MPa压力。

此外，氢气容器内胆必须能够承受因频繁充放电而引起的温度急剧变化，尼龙内胆在-40至85摄氏度的温度范围内具有优异的抗冲击性。

 

预计到 2030 年每年替代进口将达到 2700 亿韩元

此次开发的成功，为晓星TNC作为国内公司首次进入被国外公司垄断的尼龙内胆市场奠定了基础。

据专门研究氢市场的研究机构H2 Research称，全球氢汽车市场将稳步增长，包括从2025年开始，欧洲主要城市地区对内燃机卡车的运营限制预计将扩大到105万辆.

因此，尼龙材料内胆市场的进口替代效应预计到2030年将增长至每年约2700亿韩元。

此外，随着氢电动汽车、无人机、有轨电车、轮船、UAM（城市空中交通）等各种氢能移动市场的扩大，尼龙作为氢容器的内衬材料有望获得更多关注。

 

完整的氢气生产、分销、储存和利用价值链

尼龙衬里有望为晓星氢价值链 的完成做出贡献。

晓星通过韩国第一的加氢站供应商、液化氢工厂和液化氢加气站的建设，将改变氢经济的版图，生产燃料罐所必需的碳纤维，构建了氢价值链用于氢燃料汽车等

这一开发的成功意义重大，因为晓星不仅在氢的生产和分配领域，而且在储存和利用领域都拥有引领全球市场的技术能力。

 

赵贤俊会长，“纤维与技术相结合，演变为关键能源材料”

晓星 TNC 的尼龙应用氢气容器于 6 月通过了氢气容器国际质量标准 (UN/ECE R134)，作为衬里材料具备了功能、质量和技术的完美。还计划与氢燃料箱制造商和汽车制造商合作进行商业测试。

晓星TNC计划将尼龙作为衬里材料的应用从商用卡车的管状拖车扩大到航行于南极洲和赤道等世界各地海域的CNG和氢气船，将耐冲击性和耐热性范围从-60至 90 摄氏度。

此外，晓星TNC利用海中废弃的再生渔网开发出世界首创的再生尼龙纤维技术，未来计划将再生尼龙应用于内衬材料，扩大环保塑料材料市场。

Cho Hyun-Joon会长表示：“晓星TNC开发的尼龙内衬材料表明，即使在被视为衰退行业的纺织行业，将其转变为高科技氢能行业关键材料的创新也可以如果它得到技术的支持，就会发生。我们将通过材料和纺织品技术为未来环保能源产业的发展做出贡献。”

Hyosung TNC (KRX:298020) announced on the 7th 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 Korean 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% lighter than metal and 50% lighter than HDPE and gas barrier property that prevents leakage of hydrogen gas is also 30% higher than metal and 50% 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, "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 said, "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."
