Scientists Have Split Seawater To Produce Green Hydrogen

Electrolysis is the splitting of water using electricity. Normally, it requires highly purified water as a feedstock. But with the demand for hydrogen as a clean fuel growing this could place demand on scarce freshwater resources. The team at the University of Adelaide achieved similar results using untreated seawater, a cheap catalyst and a standard commercial electrolyser. Seawater is an almost infinite resource and would be a great feedstock alternative. Especially for places with long coastlines and the sunlight to power electrolysis. The team still needs to iron out some side reactions and corrosion from the seawater. Next, they want to scale it up using a larger electrolyser to produce commercial quantities of hydrogen for fuel cells.
