SummaryCurrent production methodsOverviewNatural hydrogenExperimental production methodsEnvironmental impactHydrogen usesSee also

Hydrogen is industrially produced from steam reforming (SMR), which uses natural gas. The energy content of the produced hydrogen is around 74% of the energy content of the original fuel, as some energy is lost as excess heat during production. In general, steam reforming emits carbon dioxide, a greenhouse gas, and is known as gray hydrogen. If the carbon dioxide is captured and sto…
