“Brown" or “Black” Hydrogen: Produced using coal. (Ick!)
“Grey” hydrogen: Produced using natural gas (Not as bad as coal, still…)
“Blue” hydrogen: Produced using natural gas, supposedly capturing the CO₂.
“Pink” hydrogen: Produced from water using nuclear power.
“Green” hydrogen: (Typically) produced from water using renewable power (PV, Wind…)
“White” hydrogen: “Natural” or “Geologic” hydrogen. (Might be produced by drilling wells, like natural gas wells.)

(This story is about “White" hydrogen.)
