“I want to stress the word "unique", which is being used correctly for once, because what Elium offers® is completely new.” Professeur Sung Kyu Ha Our collaboration is fruitful and essential as hydrogen will play a very important role in the future and its supply is set to become a huge market, driving the production of composite hydrogen tanks. And action needs to be taken now. The world should not miss this unique opportunity to make hydrogen an important part of a low-carbon and safe energy future. This paradigm shift can already be seen in South Korea, where it is supported by the government and major companies such as Hyundai, and awaited by the population to power their homes, factories and cars using green electricity. That is why Arkema and its partners—researchers, clients, tank manufacturers—need to do all they can not to miss out on this opportunity to develop a production chain of high-performance, recyclable, sustainable tanks. Hydrogen gas is often considered environmental ly friendly, contributing to zero CO emissions. Ironically,2 however, hydrogen tanks are now made of non- recyclable thermoset epoxy-based materials that eventually generate waste from vehicles at the end of their life. Hanyang and Arkema are working together to develop recyclable hydrogen tanks and to replace non- recyclable materials in hydrogen vehicles with Elium® “The Hanyang Structures and Composites Laboratory thermoplastic composites.” ■ has been working with Arkema since 2014 as part of the Elium composites characterization basic research® PROFESSOR SUNG KYU HA, Department of program. Our shared objectives include studying the long-Mechanical Engineering, Director of the Hanyang term behavior of thermoplastic composites, especially thoseStructures and Composites Laboratory. Hanyang made from Elium resin. In 2020, we set the Center of® University, Seoul, South Korea. Excellence for Elium Composites, CEEC, in order to extendRESEARCH AREA: Innovative application the fields of innovations using this innovative material.of Composites: hydrogen tanks, wind turbines and energy storage systems. Our work includes measuring and characterizing the mechanicalproperties of Elium/carbon composite® hydrogen tanks. To do this, we simulate and replicate the manufacturing and molding of containers for automotive production. Our added value for Arkema lies primarily in the advice we provide about tank design and use of hybrid fibers. It is by improving these two areas that Arkema will obtain the certification needed to use Elium® resin in tanks on the market. 25
