Purpose and goal
The overall aim is to develop material solutions which will facilitate the use of hydrogen gas and thus contribute to the development of a fossil-free society. This will be done by investigating the potential of two surface treatments on austenitic and ferritic stainless steels to increase their resistance to HE when used in H2 applications.
Expected effects and result
The knowledge gained in this feasibility study will be valuable to stakeholders working with H2 applications such as H2storage, transport and production. The development of a new coatings that reduce hydrogen diffusion and increase hydrogen resistance will enable the use of other steel grades that without the coating would not be adequate for H2 applications. Project findings will be disseminated through the deliverables outlined in the project plan, including presentations at hydrogen seminars.
Planned approach and implementation
The project has 5 work packages (WP): WP1: Material procurement, specimen preparation, and setting test parameters. WP2: Surface treatments to reduce hydrogen diffusion, with coating characterization. WP3: Testing coating performance in hydrogen permeation and uptake via autoclave exposure and quantification techniques. WP4: Scaling to a full project, assessing feasibility in varied conditions, and engaging larger consortium. WP5: Project management, reporting, and dissemination.
