This study aims to numerically assess the impact of wettability and relative permeability hysteresis on hydrogen losses during underground storage (UHS) explore strategies minimize them by using an appropriate cushion gas. The research utilizes Carlson model calculate saturation trapped gas Killough account for water hysteresis. By incorporating Land coefficient based laboratory-measured data a hydrogen/brine system, our findings demonstrate significant influence recovery factor when H2 is used as base model, which neglects effect, indicates 78% fourth cycle, can be improved. In contrast, modified considers results in approximately 17%, shows 45% cycle. Additionally, has notable production, with observed 12.5% increase volume that incorporates Furthermore, optimization process was conducted evaluating different gases such CO2, N2, CH4, latter proving optimal choice. These enhance accuracy estimating factor, crucial assessing feasibility projects.

Identification of early opportunities for simultaneous H2 separation and CO2 storage using depleted coal seams

Separation and Purification Technology, Год журнала: 2023, Номер 330, С. 125364 - 125364

Опубликована: Окт. 14, 2023

Hydrogen (H2) production by steam methane reforming (SMR) is an economically viable technique on a commercial scale. However, this process produces large amounts of carbon dioxide (CO2), which eventually negates the benefits employing H2 as industrial input and clean energy carrier. This issue has led to increasing interest in capturing CO2 emissions from SMR produce H2. study proposes investigates use coalbed (CBM) resources for separating mixture gases. The competitive adsorption mechanism CBM not only can separate gas but also results into geological storage at same time. idea inject depleted coal seam another well offset distance. work studies proposed using multi-physics simulation model based available data literature. accounts multicomponent, multi-phase flow, swelling/shrinkage, diffusion, sorption. Several simulations were performed investigate feasibility separation CBM. Proof-of-concept showed over 80% 90% storage. result shows that be simultaneously with high efficiency.

Abstract The goal of this research is to investigate the use different gases serve as cushion minimize H2 loss in underground storage (UHS). A detailed study performed using a compositional numerical reservoir simulator. We constructed base model that uses gas. Next, we developed three scenarios where CH4, N2, and CO2 are used gas, analyzed impact each gas on overall performance UHS. fluid account for density viscosity mixture gases. Our results indicated CH4 emerges optimal choice, followed by subsequently CO2. However, maximizing recovery from 63% 77% was at cost lowering purity. Yet, an alternative played vital role minimizing spreading hydrogen, consequently preventing into formation.
