曉星TNC (KRX:298020) 7日宣布，韓國公司首次利用自主技術成功開發并使用尼龍作為氫燃料儲罐的內襯材料。

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

襯里是在燃料箱的內部容器中儲存氫氣并防止泄漏所需的核心部件。

曉星 的尼龍材料在重量輕、阻氣性和抗沖擊性方面優于傳統的金屬和高密度聚乙烯 (HDPE) 襯里材料。

 

比金屬更輕、更安全……對溫度波動具有出色的抗沖擊性

曉星開發的尼龍襯里材料比金屬輕70%，比HDPE輕50%，防止氫氣泄漏的阻氣性也比金屬高30%，比HDPE高50%。

金屬內膽較重，長時間接觸氫氣易脆化，而尼龍內膽吸氫性和透氣性低，不存在脆化風險。

HDPE 內襯用作 40MPa水平的高壓容器，但無法承受典型氫電動汽車所需的 70MPa壓力。

此外，氫氣容器內膽必須能夠承受因頻繁充放電而引起的溫度急劇變化，尼龍內膽在-40至85攝氏度的溫度范圍內具有優異的抗沖擊性。

 

預計到 2030 年每年替代進口將達到 2700 億韓元

此次開發的成功，為曉星TNC作為國內公司首次進入被國外公司壟斷的尼龍內膽市場奠定了基礎。

據專門研究氫市場的研究機構H2 Research稱，全球氫汽車市場將穩步增長，包括從2025年開始，歐洲主要城市地區對內燃機卡車的運營限制預計將擴大到105萬輛.

因此，尼龍材料內膽市場的進口替代效應預計到2030年將增長至每年約2700億韓元。

此外，隨著氫電動汽車、無人機、有軌電車、輪船、UAM（城市空中交通）等各種氫能移動市場的擴大，尼龍作為氫容器的內襯材料有望獲得更多關注。

 

完整的氫氣生產、分銷、儲存和利用價值鏈

尼龍襯里有望為曉星氫價值鏈?的完成做出貢獻。

曉星通過韓國第一的加氫站供應商、液化氫工廠和液化氫加氣站的建設，將改變氫經濟的版圖，生產燃料罐所必需的碳纖維，構建了氫價值鏈用于氫燃料汽車等

這一開發的成功意義重大，因為曉星不僅在氫的生產和分配領域，而且在儲存和利用領域都擁有引領全球市場的技術能力。

 

趙賢俊會長，“纖維與技術相結合，演變為關鍵能源材料”

曉星 TNC 的尼龍應用氫氣容器于 6 月通過了氫氣容器國際質量標準 (UN/ECE R134)，作為襯里材料具備了功能、質量和技術的完美。還計劃與氫燃料箱制造商和汽車制造商合作進行商業測試。

曉星TNC計劃將尼龍作為襯里材料的應用從商用卡車的管狀拖車擴大到航行于南極洲和赤道等世界各地海域的CNG和氫氣船，將耐沖擊性和耐熱性范圍從-60至 90 攝氏度。

此外，曉星TNC利用海中廢棄的再生漁網開發出世界首創的再生尼龍纖維技術，未來計劃將再生尼龍應用于內襯材料，擴大環保塑料材料市場。

Cho Hyun-Joon會長表示：“曉星TNC開發的尼龍內襯材料表明，即使在被視為衰退行業的紡織行業，將其轉變為高科技氫能行業關鍵材料的創新也可以如果它得到技術的支持，就會發生。我們將通過材料和紡織品技術為未來環保能源產業的發展做出貢獻。”

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."
