Hydrogen traps can be introduced into the material microstructure to immobilize or trap absorbed hydrogen, limiting the amount of hydrogen participating in the embrittling process. This study finds that adding the chemical element molybdenum to steel reinforced with Ti-carbides markedly enhances its ability to trap hydrogen.

After the story of the blue LED, it just makes me wonder who will find this solution, and my bet is not with conventional thinking based and/or investor driven corporations.
