Question: "what is a negative effect of hydrogen on storage tanks as stated in the text" Context: "Hydrogen is highly soluble in many rare earth and transition metals and is soluble in both nanocrystalline and amorphous metals. Hydrogen solubility in metals is influenced by local distortions or impurities in the crystal lattice.
