Natural hydrogen (known as white hydrogen, geologic hydrogen[1] or gold hydrogen), is hydrogen that is formed by natural processes[2][3] (as opposed to hydrogen produced in a laboratory or in industry). By contrast green hydrogen is produced from renewable energy sources, while grey, brown, blue or black hydrogen are obtained from fossil fuels.[4] White hydrogen may be renewable. It is non-polluting and offers lower costs than industrial hydrogen.[5] Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.[6][7]
