Natural Hydrogen

Natural hydrogen (known as white hydrogen), is naturally occurring molecular hydrogen on or in Earth. (as opposed to hydrogen produced in the laboratory or in industry).

The name white hydrogen distinguishes it from green hydrogen, which is produced from renewable energy sources from the electrolysis of water, and from grey, brown or black hydrogen, which is obtained from fossil sources.

[2] Natural hydrogen is a renewable, non-polluting fuel that is a lower cost operation compared to industrial hydrogen.

[3] Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.[4] [5] (Wikipedia)
