Natural hydrogen

Natural hydrogen (also known as white hydrogen, geologic hydrogen, geogenic hydrogen, or gold hydrogen) is molecular hydrogen present on Earth that is formed by natural processes as opposed to hydrogen produced in a laboratory or in industry.

Modelling suggests that enough natural hydrogen exists to meet humanity's demand for hydrogen for thousands of years, however most of this cannot be extracted economically. Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate. As of 2023, only one well of natural hydrogen has been exploited, producing enough gas to generate electricity for a village in Mali.
