1 Production

Hydrogen was first produced in the 1600’s in a lab setting by reacting metals with acids, but it was not isolated and named until the late 1700’s. Research and advances continued through the 1800’s, but industrial scale hydrogen production methods didn’t become prevalent until the 1900’s.

Today, industrial scale hydrogen is produced by several methods with the most prominent ones (Steam Reforming, byproduct recovery from Chemical Production and Electrolysis) described here, in more detail. Other processes (not described here) include Gasification, Partial Oxidation, Autothermal Reforming, Pyrolysis and Cracking. In the future Hydrogen may be produced through photoelectrochemical water splitting, Thermochemical water splitting or Biological processes.

Electrolysis

Water Electrolysis, is the process of applying a direct electrical current through an electrolyte to split water into hydrogen and oxygen.
