project that looks to build safe pipeline infrastructure for hydrogen transportation. The HyLINE project was launched in 2019 by SINTEF, one of Europe’s largest independent research organizations, and the Norwegian University of Science and Technology NTNU. Together with Tenaris, leading industrial partners such as Gassco, Equinor, TechnipFMC, NEL and AirLiquide are contributing to the initiative, with the participation of the Research Council of Norway.
The HyLINE project is looking to convert the existing Norwegian pipeline infrastructure of 8,800 km-subsea network to a hydrogen network, and create a new hydrogen network along with it. This project is a key step for the European Hydrogen Backbone Initiative that envisions a 6,800 km hydrogen network by 2030 and a 22,900 km network by 2040. To achieve this goal, numerous challenges need to be met with safety as the most critical aspect, such as material susceptibility to hydrogen embrittlement.
The joint industrial program is organized by different tasks, from the nano level, studying the micro scale effects of hydrogen, to the macro, the understanding and quantifying the effects of hydrogen on material performance and structural integrity.
