USGS researchers have introduced a groundbreaking map showcasing potential hydrogen gas reserves across the contiguous United States. The map indicates various regions where substantial hydrogen resources may be present underground and feasibly extracted. The revelation of these extensive hydrogen reserves defies prior assumptions and opens up new possibilities for energy sourcing. Sarah Ryker from USGS expressed astonishment at the findings, highlighting that the map challenges long-held beliefs about natural hydrogen accumulation. The map's color-coded system designates highly prospective areas in dark blue, encompassing states like Michigan, Kentucky, North Dakota, Kansas, Colorado, Wyoming, Iowa, and Oklahoma. These regions exhibit the ideal combination of hydrogen sources, reservoir rocks, and natural seals conducive to trapping the gas underground. Geologic hydrogen, also known as 'gold hydrogen,' forms through chemical reactions within rocks, presenting a valuable energy asset. The research signifies a significant advancement in identifying and potentially harnessing vast hydrogen reserves for future energy needs.
