Mini-tests for in-service monitoring of structures applied to hydrogen transportation

Industrial structures for power generation and transmission are designed to have a life span of more than 40 years. Knowledge of the evolution of materials over very long periods is therefore crucial to ensure the safety and reliability of these facilities. In addition, in the context of decarbonization of energy sources, hydrogen produced by water electrolysis, for example, will play an important role. It is envisaged to collect and distribute the hydrogen produced in this way (mixed with fossil methane or biogas) using existing networks. It is then crucial to qualify the suitability of the different sections for the transport of hydrogen gas. In order to monitor the evolution of the materials throughout the lifetime of the installations and to qualify their suitability for the transport of hydrogen, the MESSIAH Chair program proposes to use mini-tests machined from coupons extracted from the installations.

The MESSIAH Chair brings together a producer of steel pipes used in energy transport (Mannesmann) and three major players (GRTgaz, EdF, Air Liquide). A software developer/distributor (Transvalor) ensures the valorization of the numerical developments made during the project.
