Hydrogen Fuel - Energy
www1.eere.energy.goveffective hydrogen infrastructure has yet to be estab-lished. Gaseous hydrogen storage systems are large and heavy to accommodate the low volumetric energy density of hy-drogen. Liquid hydrogen storage systems are much smaller and lighter, but must operate at cryogenic tem-peratures. Alternatively, if hydrogen is stored as a hydro-
HYDROGEN SULFIDE IN DRINKING WATER
publications.tamu.eduhydrogen sulfide The recommended treatment to remove hydro-gen sulfide from a water supply depends largely on the gas concentration. Trace amounts of hydrogen sulfide (0.05 - 0.3 mg/l) Activated carbon adsorbs soluble organic com-pounds and certain gases, such as chlorine and hydrogen sulfide, that contribute tastes and odors to a water supply.
