How is hydrogen produced commercially?

Answer 1

"electrifying water to separate the oygen and the hydrogen" (aka electrolysis) is very expensive and is only used to create laboratory grade hydrogen. According to this source:

most commercial hydrogen is created from hydrocarbons, like natural gas and petroleum byproducts. The author of this article claims that creating hydrogen this way creates more CO2 than burning the hydrocarbons for fuel directly.

Answer 2

Hydrogen is primarily produced commercially through steam methane reforming, a process where methane reacts with steam at high temperatures to produce hydrogen and carbon monoxide. Other methods include electrolysis, where water is split into hydrogen and oxygen using electricity, and coal gasification, where coal is reacted with steam and oxygen to produce hydrogen.
