Storage of hydrogen with methane in underground reservoirs: forecast of associated processes

Abstract

Based on the generalization of world experience in the underground storage of hydrogen with methane and the experimental work performed, the authors predict the development of hydrochemical, microbiological, geomechanical processes and phenomena that, in a real geological environment, will most likely accompany the joint storage of hydrogen and methane in underground formations. The issues of gas diffusion through the tire and hydrogen losses due to its consumption by microorganisms are also considered. Theoretical solutions are illustrated by calculations on synthetic models. Keywords: underground gas storage; hydrogen; methane; anaerobic microorganisms.
