Hydrogen gas induced degradation of mechanical properties in new applications - HYMECH II

Purpose and goal:

Hydrogen technologies are extremely important in reaching the goal of a fossil-free society. Metallic materials will be used for processing, transporting and storing hydrogen gas (H2), however, the possible uptake of hydrogen in metals can lead to hydrogen embrittlement (HE) resulting in catastrophic and premature failures. In this project we aim to evaluate the effect of H2 on the mechanical properties of metals in relevant service conditions corresponding to H2 storage and transport, automotive and power generation.

Expected results and effects:

Hydrogen as energy carrier has great potential to transform manufacturing, automotive and energy industries towards carbon neutrality by using hydrogen for example for combustion processes, fuel cells, energy storage and ore reduction. However, to be able to apply these technologies a complex infrastructure needs to be built and maintained. This includes both production of hydrogen, transport and storage.

Experimental testing to evaluate material compatibility in H2 environment will be a necessary part of the adoption of these emerging hydrogen technologies. Approach and implementation: The project is divided in 7 Work packages: WP1: Procurement of materials: Delivery, welding and characterization WP2: Storage and transport

WP3: Automotive: combustion engines WP4: Power generation and heating technologies WP5: Metal-H2 interaction and the effect on HE WP6: Technical report and open guide on materials for H2 applications WP7: Project management, reporting and dissemination
