Seawater is the most abundant source of chemical energy and could soon be used for the production of hydrogen
Creating hydrogen fuel from seawater - technology short science news

Hydrogen is an appealing option for fuel, because burning it produces only water, no carbon dioxide. As powering cars and cities would take enormous amounts of hydrogen, it seems impossible to use purified water to obtain sufficient amounts of hydrogen, especially in more arid areas of the planet.

Now researchers have discovered a way to split seawater (the Earth’s most abundant source for chemical energy) into hydrogen and oxygen by a process called electrolysis. The corrosive effects of chloride in the seawater was prevented by a special coating on the anode.

This method might prove useful for hydrogen production at large scale in the future.
