“…In The introduction of hydrogen into steels and most metals, even as low as 1 ppm (0.0001 wt%), can cause cracking in structures [45]. The susceptibility of metals to HE is mainly observed in BCC and HCP crystal structures metals and alloys, while FCC metals like aluminum alloys, although susceptible to hydrogen embrittlement [46], are not as severely susceptible as BCC and HCP metals. This is due to the ability of FCC metals to dissolve higher amounts of hydrogen with traps (irreversible) that are capable of holding the hydrogen atoms and preventing them from diffusing.…”

“…This is due to the ability of FCC metals to dissolve higher amounts of hydrogen with traps (irreversible) that are capable of holding the hydrogen atoms and preventing them from diffusing. A range of defects in the aluminum FCC crystal structure such as lattice vacancies, dislocations, and grain boundaries are potential trapping sites for hydrogen [46], thus preventing the dissolved hydrogen from diffusing due to stress fields within the metal crystal lattice, e.g., crack tips, and also encouraging crack growth. For steels, the most effective sites are the microvoids and the interface of steel and non-metallic inclusions like Fe 2 O 3 , Fe 3 O 4 , MnS, Al 2 O 3 , TiC, Ce 2 O 3 [38] and the percentage of the austenitic (FCC, γ-iron) phase.…”

Global warming is an accepted fact of life on Earth, posing grave consequences in the form of weather patterns with life-threatening outcomes for inhabitants and their cultures, especially those of island countries. These wild and unpredictable weather patterns have persuaded authorities, governments, and industrial leaders to adapt a range of solutions to combat the temperature rise on Earth. One such solution is to abandon fossil fuels (hydrocarbons) for energy generation and employ renewable energy sources, or at least use energy sources that do not generate greenhouse gases. One such energy carrier is hydrogen, which is expected to slowly replace natural gas and will soon be pumped into the energy distribution pipeline network. Since the current energy distribution network was designed for hydrocarbons, its use for hydrogen may pose some threat to the safety of urban society. This is the first time an overview article has examined the replacement of hydrocarbons by hydrogen from a totally different angle, by incorporating material science viewpoints. This article discusses hydrogen properties and warns about the issue of hydrogen embrittlement in the current pipeline network if hydrogen is to be pumped through the current energy distribution network, i.e., pipelines. It is recommended that sufficient study and research be planned and carried out to ensure the safety of using the current energy distribution network for hydrogen distribution and to set the necessary standards and procedures for future design and construction.

~bstracL Susceptibility of aluminium and its alloys towards hydrogen embrittlement has been well established. Still a lot of confusion exists on the question of transport of hydrogen and its possible role in stress corrosion cracking. This paper reviews some of the fundamental properties of hydrogen in aluminium and its alloys and its effect on mechanical properties. The ~mportance of hydrogen embrittlement over anodic dissolution to explain the stress corrosion cracking mechanism of these alloys is also examined in considerable detail. The various experimental findings concerning the link between hydrogen embrittlement and stress corrosion cracking are also discussed.
