Abstract
It was shown, that porous nickel, the absorption was 0.7 wt.% at 15 atm and 300◦C. Magnesium absorbed hydrogen up to 1.5 wt.%. The aluminum-nickel alloy samples did not show any hydrogenation under any conditions. Titanium powders absorbed hydrogen at a level of 3.8 wt.% at 12 atm and 700◦C, which is slightly lower than the theoretical value of 4.04 wt%. TiH2.Lithium LiH samples showed high absorption values. At 700◦C and a pressure of 12 atm, the amount of hydrogen in lithium metal was 12.5 wt.% , therefore, to obtain good absorption (> 6 wt.%) requires high temperatures (700◦C) and high pressures (> 15 atm).
