Hydrogen can be obtained economically as a byproduct in the electrolysis of "brine".
A solution of sodium chloride (NaCl)and water (H2O) refers to the brine.The procedure of electrolysis includes utilizing an electric current to achieve a synthetic change and make new chemicals. The electrolysis of brine is a huge scale process used to make chlorine from salt, so three important chemicals, NaOH, Cl2, H2, can be gotten by electrolyzing brine.

There are too many popular methods of production of hydrogen are there. But it is one of the simplest and easy and understandable economic process is electrolysis of water.
Since water contains hydrogen and oxygen gases , it has to be separated by electrolysis method. In electrolysis method Hydrogen ions and oxygen ions are separated by the electrolyzer and catched up the cathode and anode electrodes respectively. Since hydrogen ion is positively charged and attracted by the cathode and oxygen ion is negatively charged attracted by the anode. Here the following reactions are undergoing in electrolysis process as follows :
2H^2^0 ----> 2H^2 + O^2
