Relationship between clay minerals and microorganisms in underground hydrogen storage reservoirs: a mini review

Frontiers in Energy Research, Journal Year: 2025, Volume and Issue: 13

Published: Feb. 7, 2025

Hydrogen (H 2 ) will play a vital role in the global shift towards sustainable energy systems. Due to high cost and challenges associated with storing hydrogen large quantities for industrial applications, Underground Storage (UHS) geological formations has emerged as promising solution. Clay minerals, abundant subsurface environments, critical UHS by providing low permeability, cation exchange capacity, stability, essential preventing leakage. However, microorganisms subsurface, particularly hydrogenotrophic species, interact clay minerals ways that can affect integrity of these storage Microbes form biofilms on surfaces, which cause pore clogging reduce permeability reservoir, potentially stabilizing H limiting injectivity. Microbial-induced chemical weathering, through production organic acids redox reactions, degrade releasing metal ions destabilizing site. These interactions raise concerns about long-term capacity UHS, microbial processes could lead loss caprock degradation, compromising system’s effectiveness. This mini review aims cover current understanding between how dynamics safe deployment .

Amidst the rapid development of renewable energy, intermittency and instability energy supply pose severe challenges impose higher requirements on storage systems. Among various technologies, coupled approach power-to-hydrogen (H2) underground H2 (UHS) offers advantages such as extended duration large-scale capacity, making it highly promising for future development. However, during UHS, particularly in porous media, microbial metabolic processes methanogenesis, acetogenesis, sulfate reduction may lead to consumption production byproducts. These activities can impact efficiency safety UHS both positively negatively. Therefore, this paper provides a comprehensive review experimental, numerical, field studies interactions within aiming capture research progress elucidate effects. It begins by outlining primary types key involved. Subsequently, introduces experimental approaches investigating gas-water-rock-microbe interfacial properties, models simulators used numerical studies, procedures implemented trials. Furthermore, analyzes discusses their positive negative impacts focusing aspects consumption, flow, safety. Based these insights, recommendations site selection, engineering operations, on-site monitoring well potential directions, are provided.

Feasibility Assessment of Symbiotic Processes Between Hydrogen and CO2 Storage in Coal Seams of Various Ranks

Published: Oct. 11, 2024

Abstract Carbon dioxide (CO2) and hydrogen (H2) can be symbiotically stored in coal seams, as an effective method for storing H2 to facilitate the transition from fossil-based energy systems renewable sources sequestering growing amounts of captured CO2 meet carbon neutrality goals. The key challenge this process lies determining interactions between different fluid components fluids rocks, a typical dual-porosity medium. This research first derives governing equations depict flow behavior multi-component gases fracture matrix. effect unconventional stress (UES) on reservoir deformation presence multicomponent are also characterized by control equations. Then UES-dependent porosity permeability models were developed explicitly quantify such interactions. A fully coupled numerical model was established characterize response when symbiotic stored. We subsequently validate through experimental data then use simulate cyclic operations storage seams. results injection production reservoirs support main conclusions are: 1. cushion increases pressure prevent significant amount waste; 2. Under gas stripping effect, desorbs matrix transfers into system mix with H2. mixing phenomenon becomes increasingly pronounced progression cycles, leading gradual decrease purity withdrawn H2; 3. during decreases recovery; 4. larger adsorption strain constant H2, greater corresponding fictitious stress, resulting smaller fluctuations processes; 5. Low-rank seams exhibit best injectivity productivity performance, while high-rank have highest unit capacity CO2. demonstrate that used interaction working gas, well rocks. proofs feasibility
