Geological hydrogen, often referred to as white or natural hydrogen, represents a paradigm shift in our understanding of Earths energy resources. Unlike manufactured hydrogen produced through electrolysis or steam methane reforming, geological hydrogen is generated naturally beneath our feet by ongoing, Earth-driven chemical reactions. The most common process, known as serpentinization, occurs when groundwater percolates down into deep iron-rich rocks, such as olivine and pyroxene, found in the Earths mantle. As the water reacts with these ferrous minerals at high temperatures and pressures, it oxidizes simply click the up coming web site iron, producing magnetite and releasing hydrogen gas as a byproduct. This reaction is not a relic of the distant past; it happens continuously today wherever tectonic activity creates new fractures.
