ABSTRACT

Hydrogen consuming microorganisms can cause operational challenges for
subterranean hydrogen storage. The systems and methods described herein
provide sterilization techniques that include acidifying a subterranean
reservoir prior to injection of hydrogen. Acidification may be facilitated by,
at least partially, saturating a fluid with an acidifying agent such as carbon
dioxide. The subterranean reservoir's fluid may be reduced to 3 pH to 4
pH. Hydrogen may then be injected into the subterranean reservoir for storage.
