Green Hydrogen From Ordinary Seawater, a Near Infinite Resource: Semafor

Getting hydrogen from seawater: Unedited


Researchers made green hydrogen out of ordinary seawater. 

The clean-burning gas is created by splitting water with electricity — a potential way of storing renewable energy and powering a zero-carbon economy. Existing methods involve using costly purified water.

But Australian researchers found a cheap way of harnessing seawater, by first treating electrodes so they don’t get encrusted by the water’s salt and minerals.

The method stores almost as much energy as it uses to split the water molecules, and since seawater is a near-infinite resource, could render hydrogen a more realistic fuel.
