Alternative form of gray hydrogen

Hydrogen that is generated entirely with power from renewable energy and the electrolysis of water; which generates no carbon pollution.

hydrogen generated from methane feedstock, typically from natural gas/petroleum gas, whose carbon residue, typically carbon dioxide, is captured, resulting in a low-carbon process.

Deuterium.

(inorganic chemistry) The systematic alkali name for water.

(inorganic chemistry) A colourless gas having an irritating smell; it has the molecular formula HBr, and dissolves in water to form hydrobromic acid; it has many industrial applications including the production of barbiturates and synthetic hormones.

(inorganic chemistry) a colourless gas with molecular formula HI, having a suffocating smell; it forms hydriodic acid when dissolved in water

(chemistry) a colourless fuming liquid or gas, having a molecular formula of HF; it dissolves in water to form hydrofluoric acid and has many industrial uses including the production of Teflon and the refining of uranium; it corrodes skin, flesh and bone, and any skin contact must be avoided

(inorganic chemistry) A colourless liquid, H₂O₂, soluble in water, used as a mild antiseptic, bleaching agent (especially for bleaching hair), oxidizing agent and chemical reagent.

(inorganic chemistry) A colourless, very poisonous, volatile liquid, HCN, used in the production of dyes, plastics and fumigants; it dissolves in water to form hydrocyanic acid and reacts with bases to form cyanides, and with some organic compounds to form nitriles.
