Direct Seawater Electrolysis

The Modified Direct Seawater Electrolysis Process* for efficient Green Hydrogen production solves one of the major constraints of conventional water electrolysis, which requires potable water.

Freshwater is likely to become a scarce resource for more than 80% of the world’s population, while the desalination of seawater, its further purification, and transportation contribute additional costs.

Seawater could be an abundant source of hydrogen. However, direct seawater electrolysis is currently used commercially for chlorine production. Hydrogen is generated as a by-product.

The main challenges of direct seawater electrolysis:
– Production of toxic chlorine and corrosion at the anode;
– Magnesium hydroxide & calcium carbonate precipitation;
– Low electrolyte conductivity resulting in high power requirements.

The proposed Modified Direct Seawater Electrolysis Process solves these challenges and provides a more economical way for the electrolytic hydrogen production compared to conventional water electrolysis.

Advantages:
– Capable of operating with seawater directly;
– No need for disposal of desalination brine;
– Requires much less electricity than conventional water electrolysis.

The lower energy consumption of the MDSE process reduces the cost of Green Hydrogen production to a level comparable to Grey Hydrogen from fossil fuels.
