Abstract
H2, which is formed by the oxidation of iron in rocks, was likely a critical source of energy for early life. Analysis of natural rock samples from 3.5–2.7 billion-year-old komatiites, combined with geochemical data from a global database, quantifies the amount of H2 likely to have been produced in Earth’s ancient oceans.
