The EU's Green Deal and Hydrogen Strategy prioritize hydrogen production, infrastructure, and industrial decarbonization for zero-emission transport. Finland's Hydrogen Roadmap emphasizes hydrogen integration into key industries, aiming for clean energy innovation leadership. Aluminum is a candidate for zero-emission transport due to its lightweight, but its sensitivity to hydrogen limits its application. Meanwhile, additive manufacturing (AM) offers promising potential for producing complex, energy-efficient structures; however, its nonuniform nature complicates the assessment of hydrogen interactions, making the process time-consuming and costly. This study aims to identify the key factors controlling the sensitivity of aluminum alloys, both AM and wrought, to hydrogen and develop a model for fast assessing hydrogen interactions with these materials. Understanding these factors will help optimize both AM and wrought aluminum alloys for improved performance in hydrogen environments.
