A focused review of the hydrogen storage tank embrittlement
Embrittlement is a process, by which various metals, mainly high-strength steels, become brittle and crack after being exposed to hydrogen [ 12 ]. It is caused by the ingress of either molecular or atomic hydrogen into a metal lattice [ 64 ]. However, the exact mechanism of hydrogen embrittlement is not clear.
