Electrolyzers need ultra-pure water, hence adding substantial cost to Hydrogen production, especially in the developing world that has limited availability of clean water.

Hydrogen is a widely available element; we can find it all around us i.e. in the form of water, fossil fuel, and biomass. It took the central stage as an energy carrier in the transition towards Net-Zero.

As electrolysis of water is the most talked-about process for green hydrogen production, lots of studies and demonstration projects have been done in order to reduce production costs to optimal levels. 

Among many factors of hydrogen production cost, one is filtration and demineralization of the water. As almost all electrolyzers need ultra-pure water. 

German automotive supplier Schaeffler partners with start-up Hydron Energy BV for a pilot project that demonstrates the use of electrolyzer’s waste heat to distill the seawater. 

As I mentioned in my article “Role of Heat in Decarbonisation” increases the overall efficiency of the process and system. 

It is estimated it will help in the reduction of LCOH from the current level of €10/Kg H2 to desired €2 / Kg H2.

Get in touch if you are looking forward to netzero Transition and want to discuss your project.

Thank you for the post.  This might be used for the briny waters of many oil wells, also.

Yes, I agree. However, I am not sure about the environmental implications in the case of brine water.
