Is it possible to make green hydrogen out of seawater?

Renewable H2 will be an important part of the decarbonization mix, but it requires water.With the price of renewable electricity on the decline, the production of green hydrogen is becoming an increasingly viable option.This type of H2 is made using renewable electricity to power water electrolysis.That said, electrolyzers that produce green hydrogen typically depend on pure water, despite the fact that the most abundant form of H2O is seawater. With the broad availability of salt water, research has been aimed at developing electrolysis that would be able to use salt water directly for mass H2 production.  As a result, many now wonder if there is a real possibility of using this type of technology or if the challenge simply doesn’t look promising.Desalination PlantAmong the most important struggles resulting from using seawater in electrolysis is that it corrodes electrodes…
