Foam phase hydrogen
WebStorage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C. Hydrogen can also be stored on the surfaces of solids (by adsorption) or … WebJan 3, 2003 · The high ER l in the lower foam phase was largely attributable to the abrupt increase in εg (from 0.25 to 0.75), or the a (from about 12 to 25 cm2/cm3) from the bulk liquid to the foam phase.
