Natural hydrogen, referred to as native hydrogen or 'white or gold' hydrogen, is a naturally occurring gas that has attracted considerable attention globally due to its potential as a clean and abundant energy source. Emissions of natural hydrogen have been documented worldwide since ancient times, with notable occurrences in places like Mount Chimaera in Turkey and Mali's Bourakébougou village. Recent exploration efforts have seen countries like Australia, the US, and various European and Asian nations actively searching for natural hydrogen reserves. The US Geological Survey and organizations like CSIRO in Australia are at the forefront of research and development in this field. Geological processes like serpentinization, geothermal activities, and organic matter pyrolysis are instrumental in the creation and movement of natural hydrogen within the Earth's subsurface. This unique gas can accumulate in various types of rocks, offering potential reservoirs for storage. While challenges exist in identifying and assessing these deposits, advancements in technology and geological understanding provide hope for leveraging natural hydrogen as a sustainable energy solution. The exploration and evaluation of natural hydrogen deposits continue to unfold, shaping a potential future where this resource could play a crucial role in global energy transitions.
