Non-Interrupted and with No Corrosion Hydrogen Production from Un-Treated Direct Sea Water


Nowadays the energy industry and research laboratories are heavily working on developing methods and ideas to reduce and/or eliminate the carbon dioxide emission in efforts to control the climate’s global warming. One of the solutions is to find other energy resources to reduce the global dependence on conventional hydrocarbon energy. Green Hydrogen gas from water stands on the top of the alternative resources that does not produce carbon dioxide when burned and in turn doesn’t add to global warming. Since water is the largest resource on earth, this makes the hydrogen production from water the most attractive solution. It is very important to stress on the importance of not considering fresh water as a source of energy due to the need of humans, animals, plants …etc. on such very limited resources.

Technology Overview

The direct method to produce hydrogen gas from the sea water is to use the electrolysis technique. This technique requires a direct current, DC power supply, a positive electrode, and a negative electrode. The outcome of the electrolysis is decomposing the salt water to its positively charged Hydrogen and Sodium ions at the negative electrode and its negatively charged Oxygen and Chlorine ions at the positive electrode.


  • Increasing the rate of the hydrogen production by eliminating the constraint of the low electric current used to slow down the corrosion rate
  • Using a very low cost, easy to manufacture and none corrosive electrodes 
  • Isolate the chlorine inside the electrode resulting in a clear sea water throughout the entire hydrogen production process


A very low cost and powerful solution to the corrosion problem is introduced, tested and experimentally proven. The solution relies on replacing the classic metallic positive electrode with a non-metallic one. The non-metallic electrode is made of rock portions that have high porosity, pore volume, and high permeability, pores connectivity, saturated with saline water. Any rock with the above properties exhibits very low resistivity
