One of the major challenges in harnessing energy from renewable sources like wind and solar is their intermittent nature. Energy production these can vary based on weather conditions time day, making it essential to store surplus for later use when there a shortfall. storage systems play crucial role addressing this intermittency issue ensuring stable reliable supply. Green hydrogen, sourced renewables, emerges as promising solution meet rising demand sustainable energy, depletion fossil fuels environmental crises. In present study, underground hydrogen various geological formations (aquifers, depleted hydrocarbon reservoirs, salt caverns) examined, emphasizing need detailed analysis potential hazards. The paper discusses associated with storage, including requirement extensive studies understand interactions microorganisms. It underscores importance issue, focus reviewing past projects sites, well modeling field. also emphasizes incorporating hybrid into overcome limitations standalone systems. further explores future integrations green within dynamic landscape.

Subsurface hydrogen storage controlled by small-scale rock heterogeneities

International Journal of Hydrogen Energy, Journal Year: 2024, Volume and Issue: 60, P. 1192 - 1202

Subsurface porous rocks hold significant hydrogen (H2) storage potential to support an H2-based energy future. Understanding H2 flow and trapping in subsurface is crucial reliably evaluate their efficiency. In this work, we perform cyclic visualization experiments on a layered rock sample with varying pore throat sizes. During drainage, follows path consisting of large pores throats, through low permeability layer, substantially reducing capacity. Moreover, due the heterogeneity depending experimental strategy, imbibition unexpectedly results higher saturation compared drainage. These emphasize that small-scale heterogeneity, which often unaccounted for reservoir-scale models, plays vital role displacement media, implications efficient strategies.

Subsurface Hydrogen Storage in Limestone Rocks: Evaluation of Geochemical Reactions and Gas Generation Potential

Energy & Fuels, Journal Year: 2024, Volume and Issue: 38(11), P. 9923 - 9932

Published: May 14, 2024

Underground hydrogen storage (UHS) in carbonate reservoirs is a suitable solution for safe and efficient recovery during the cycling process. The uncertainties associated with potential geochemical reactions between hydrogen, rock, brine may impact long-term containment of produced formations. Despite current interest studying hydrogen-rock reactions, only limited work available literature. In this study, we experimentally evaluate reactivity rocks to address gas generation induced by reactions. Limestone samples are treated under 1500 psi 75 °C temperature duration 6 13 months using simple reaction cells. Scanning electron microscopy (SEM) analysis performed examine dissolution/precipitation hydrogen. contrast, chromatography (GC analyzer) inductively coupled plasma optical emission spectroscopy (ICP-OES) conducted detect ion precipitation. experimental results indicate no significant treatment on surface morphology pore structure even after treatment, suggesting that abiotic unlikely occur first stages UHS. Furthermore, presence brine, there apparent indications occurring calcite, traces any other gases detected treatment. Besides, solutions' pH remains almost unchanged, minor increase calcium (Ca2+) ions solution, which attributed water, not promisingly support utilization storage.
