Can salt water help produce green hydrogen?

Green hydrogen is a sustainable energy carrier, which can be produced directly by water electrolysis, potentially substituting fossil fuels to attain carbon neutrality.?Renewable energy is used to produce hydrogen from water. Hence its production is free from greenhouse gases and carbon capture technology.

Electrolyzers that produce green hydrogen typically depend on pure water, despite the fact that the most abundant form of H2O is seawater.

With the amount of seawater available, research is being done to check the possibility of developing H2. Among the most important struggles resulting from using seawater in electrolysis is that?it corrodes electrodes faster than ultra-pure water.?The sodium chloride and organic salts dissolved in ocean water corrode catalytic electrodes, shortening their useful life.

Several advances have been made to help overcome many of the top challenges to the production of renewable H2.?

Stanford researcher Hongjie Dai and his team aimed to find a technique to?keep ocean water from corroding the submerged anodes?due to its high salt content. They discovered coating the anode with rich layers of negative charges reduces the breakdown of the underlying metal.

Universal Kraft works in the implementation of green efficient solutions covering the entire power production chain, and intends to be a part of the change.?We have been working with green hydrogen production for several years through our partner company?Universal H2.

We believe hydrogen could solve some of the energy transition’s biggest hurdles: storage, clean energy distribution, industry usage and heavy transport.
