The evolution of biological hydrogen oxidation as a key mechanism to prevent planetary water loss
Water is essential to planetary habitability, and Earth’s long-term water stability depends on mechanisms preventing hydrogen escape to space. Hydrogen on Earth is continually produced through geological and biological processes. While hydrogen production from water photolysis in the upper atmosphere is largely prevented by Earth’s magnetic field and atmospheric cold traps, hydrogen generated in the crust or near the planetary surface would escape to space unless oxidation processes act on it quickly. AQUA hypothesises that biological hydrogen oxidation is one of the major processes preventing planetary water loss and that it played a key role during Earth's evolutionary history. Biological…
