Microbiological and Geochemical Perspectives on Sustainable Dihydrogen Storage in Deep Aquifers.

ABSTRACT: The successful integration of dihydrogen (H₂) as an energy vector relies on effective seasonal storage in underground facilities like deep aquifers. However, the viability of this storage remains uncertain due to the unclear behavior of indigenous microorganisms in the presence of H₂, which could influence the gas composition. While modeling can inform H₂ dynamics, reactor-scale experiments are needed for validation. In our study, we used a high-pressure reactor to simulate injecting 2% H₂ into a gas storage aquifer currently used for natural gas (CH₄, 1% CO₂), utilizing formation water and rock samples from the aquifer. Our research led to a kinetic model that analyzes the interactions among gas, water, rock, and microbial
