Hidden hydrogen: Earth may hold vast stores of a renewable
WEBFeb 16, 2023 · Critically, natural hydrogen may be not only clean, but also renewable. It takes millions of years for buried and compressed organic deposits to turn into oil and gas. By contrast, natural hydrogen is always being made afresh, when underground water reacts with iron minerals at elevated temperatures and pressures.
Natural hydrogen - Wikipedia
WEBSources of natural hydrogen include: degassing of deep hydrogen from Earth's crust and mantle; reaction of water with ultrabasic rocks (serpentinisation); water in contact with reducing agents in Earth's mantle; weathering - water in contact with freshly exposed rock surfaces; decomposition of hydroxyl ions in the structure of minerals;
