Production of hydrogen by electrolysis of water pdf

Hydrogen production is the family of industrial methods for generating hydrogen. Currently the dominant technology for direct production production of hydrogen by electrolysis of water pdf steam reforming from hydrocarbons. Many other methods are known including electrolysis and thermolysis.

In 2006, the United States was estimated to have a production capacity of 11 million tons of hydrogen. 4 million tons were an incidental by-product of the chlor-alkali process.

Department of Energy, only in 2004, 53 million metric tons were consumed worldwide. There are no natural hydrogen deposits, and for this reason the production of hydrogen plays a key role in modern society. Fossil fuels are the dominant source of industrial hydrogen. Specifically, bulk hydrogen is usually produced by the steam reforming of methane or natural gas.
