Using Solar To Turn Seawater Into Hydrogen Fuel

In Clean Facts, Innovations, News, Technology

Running an electrical current through water splits it into oxygen and hydrogen, the latter of which can be used as a reliable, zero-emission fuel source.

In the past, the process of purifying water beforehand was too energy intensive for this process to be useful — but now scientists have figured out how to skip the process altogether and convert seawater into usable hydrogen.

Generating hydrogen fuel from freshwater sources would put too great a strain on everyone else who needs that water. So instead, the Stanford University and the Beijing University of Chemical Technology, scientists developed a new metal coating for the electrodes used in the experiment that would let them withstand the chemical reaction as it occurs in saltwater.

Because an electrical charge is necessary to actually split the water into hydrogen and oxygen, the scientists tried to make their apparatus as environmentally friendly as possible and powered it with solar cells.

The system could be rigged to submarines or SCUBA gear.

Hydrogen fuel cells could power the sub or the diver’s gear, while the oxygen generated from the chemical reaction could keep them stocked up with breathable air.

But any practical applications are still far off in the future, as this new research simply demonstrates that the technology could work at all.
