Microbiome associated to an H-emitting zone in the São Francisco basin Brazil.

Background: Dihydrogen (H₂) natural gas is a clean and renewable energy source of significant interest in the transition to sustainable energy. Unlike conventional petroleum-based fuels, H₂ releases only water vapor upon combustion, making it a promising alternative for reducing carbon footprints in the future. However, the microbial impact on H₂ dynamics in H-emitting zones remains unclear, as does the origin of H - whether it is produced at greater depths or within shallow soil layers.
