Saltwater could be turned into hydrogen fuel

The discovery of scientists from Stanford allows us to consider the seas and oceans as a new source of renewable energy.

The authors of the study are already considering the process of splitting water into hydrogen and gas as a potential way to get cheap energy. To obtain hydrogen, purified water is needed, and it is difficult to find it in large quantities. Therefore, scientists have tried to find a way to prevent salt water from destroying the device used for electrolysis.

In their invention, they used nickel composite foam as a conductor and iron and nickel hydroxide for electrolysis. Nickel foam protects other elements from exposure to salt water – without it, corrosion will interfere with the electrolysis process after 12 hours, and with it this process will last for thousands of hours.

So far we are far from using sea water as a source of hydrogen. Scientists have just found a way to avoid the process of water purification, and in the future we need to test the ability to scale this process.
