Hydrogen is anticipated to play a key role in global decarbonization and within the UK's pathway achieving net zero targets. However, as production of hydrogen expands line with government strategies concern where this will be stored for later use. This study assesses different large-scale storage options geological structures available UK addresses surrounding uncertainties moving towards establishing economy. Currently, salt caverns look most favourable option, considering their proven experience hydrogen, especially high purity natural sealing properties, low cushion gas requirement charge discharge rates. geographical availability can act major constraint. Additionally, substantial increase number new necessary meet demand. Salt have greater applicability good short-term solution, however, porous media, such depleted hydrocarbon reservoirs saline aquifers, seen long-term strategic solution energy demand achieve security. Porous media solutions are estimated capacities which far exceed projected Depleted fields generally been well explored prior extraction. Although many aquifers offshore UK, characterizations still required identify right candidates storage. advantages over make them favoured option after caverns.

Sandstone wettability and mixed gas composition: Unraveling the impact of CO2 in hydrogen geo-storage

International Journal of Hydrogen Energy, Journal Year: 2024, Volume and Issue: 59, P. 1352 - 1366

Published: Feb. 15, 2024

Underground hydrogen storage (UHS) is gaining interest as a secure, long-term solution for storing in porous geological formations. In UHS, cushion gas like CO2 crucial to maintain the reservoir pressure and optimize recovery. The concept of wettability plays fundamental role determining system's multi-phase displacement characteristics media. However, there gap existing literature regarding sandstone rocks under geo-storage conditions when H2 are injected bulk gases, respectively. To address this gap, we conducted study investigating hysteresis phenomenon by measuring advancing receding contact angles different mixtures H2/CO2 with brine on mineral pressures temperatures, using tilted plate method. results show that angle increases pressure, leading system become less water-wet. Conversely, an increase temperature makes more Moreover, measured remains relatively constant despite changes concentration. Further analyses utilizing atomic force microscope (AFM) energy dispersive X-ray spectroscopy (EDS) indicated chemical physical structure rock does not change after exposure CO2, consistent observed lack varying fraction. conclusion, water-wet state identified decreases residual trapping H2, facilitating higher recovery but posing potential risk leakage. Hence, fraction favorable reducing decreasing IFT and, subsequently, column. This improves our understanding mechanisms, aiding accurate simulations underground systems.
