Hydrogen is gaining prominence in the energy transition, and Amorim Cork Composites has taken a significant step by investing in the development of cork composite sealing solutions for hydrogen applications. The unique properties of hydrogen demand specific adaptations in infrastructure and safety standards, making effective sealing crucial. Amorim tested cork&EPDM and cork&NBR materials under high-pressure hydrogen, exceeding standard practices by using hydrogen as the test gas. The results showed that these cork composites provide outstanding sealing in 100% hydrogen environments, ensuring safety and efficiency in storing and transporting hydrogen. This success represents a milestone in sustainable cork solutions for hydrogen sealing. Future tests will explore new materials and extreme conditions to further enhance the reliability and applicability of cork composite seals in industrial hydrogen settings.
