Hydrogen production

Today, hydrogen is mainly produced by reforming of hydrocarbons with water vapor, and via water electrolysis. Although hydrogen production via reforming is the three times cheaper than water electrolysis, the main disadvantage of such a process is the harmful carbon dioxide (CO2) emision.

Scientific research has just focused on systems that use direct methods of hydrogen production without CO2 emissions, where certainly the greatest role plays water splitting that is present in sufficient quantity.

Between all techniques of water splitting the most known are water electrolysis, thermochemical water dissociation, and water biophytolysis. Among other techniques there are mechanical – catalytic water dissociation, water plasmolysis, magnetolysis and radiolysis, and photoelectrolysis.
