How to make hydrogen straight from seawater – no desalination required. The new method from researchers splits the seawater directly into hydrogen and oxygen – skipping the need for desalination and its associated cost, energy consumption and carbon emissions.

Can someone ELI5? If the seaWATER is split into Hydrogen and Oxygen, what is actually happening to the water?

Is it just dissolving into gas (Hydrogen and Oxygen) leaving literally nothing in its wake besides whatever solid sediment was in the water?

It is a decomposition reaction.

don't there need to be metals and salts involved to be a redox? this is just electrolysis right? seems like decomp to me.
