Microbial Community in Underground Gas Storages Focused on Methanogenic Archaea and Biotechnological Potential

Extensive usage of fossilized carbon resources has proven problematic in recent years due to its footprint on nature. As such, biomethanation, the microbial production of methane from non-fossil sources, is one of the promising technologies which opens the way to a more suitable energy production. Underground gas storages (UGSs) may play a strategic role in this process. The UGSs provide a suitable environment for methanogenic archaea that are capable of converting anthropogenic carbon dioxide and renewable hydrogen into biomethane.
