A recent scientific study indicates that hydrogen gas is seeping from within the Earth in places where historically no one had expected it before.
Scientists have now identified thousands of sites in the European part of Russia where natural hydrogen gas may be found seeping out of shallow depressions. In research paper, published in
Natural Resources Research , scientists have examined many of these subcircular, shallow surface depressions seeping hydrogen gas, ranging in size from a hundred meters to several kilometers in diameter. These have been identified throughout a region extending from the Moscow region to Kazakhstan.
Using portable gas detectors, researchers found the concentration of molecular hydrogen gas in the soil of these structures was very high, up to 1.25% at 1.2 m deep.
