Надежность подземного хранения водорода совместно с метаном в терригенных геологических формациях

The main natural sources of hydrogen and associated gases – carbon dioxide and hydrogen sulfide – for storing hydrogen together with methane in geological formations are examined. The role of the main hydrochemical and microbiological processes that cause risks of leakage and loss of hydrogen due to the activation of physicochemical and microbiological reactions that affect deformation changes in the surrounding geological space of underground reservoirs is shown.
