Researchers at the University of Lyon in France have come up with a way to extract hydrogen from water using the mineral called olivine.

The green mineral is also sometimes mined as a semi precious stone known as peridot.

The chemical reaction that happens when olivine gets wet is something that takes a long time in nature, but researchers have harnessed the reaction to produce hydrogen as a potential source of energy.

When olivine is introduced to water, one hydrogen and one oxygen molecule separate from the H2O leaving the single hydrogen molecule left behind along with a byproduct of serpentine crystals.

The same chemical process happens in rocks on the floor of the ocean, but it takes a lot longer, and it is believed the hydrogen either reacts with carbon to create methane, or is consumed by microbial activity.

Current methods of hydrogen production involve steam reforming, which mixes hydrocarbons in gas or oil with water at high temperatures.

Creating hydrogen using the olivine method doesn’t require the burning of fossil fuels and it happens at a lower temperature, making it a carbon free green chemistry that might provide a sustainable source of energy for the future.
