Abstract
Residual gas trapping in porous media is a key indicator of hydrogen storage and recovery performance. The injection scheme of cushion and working gases helps maintain pressure and reduce losses. However, this information is limited in the literature. This work explores core flooding experiments (using electrical resistivity for in-situ saturation monitoring) on Bandera Grey sandstones under reservoir conditions (42 °C, 1400 psi, and 5 wt% NaCl), investigating cushion gas type and injection rate effects on storage and recovery performance. Results indicate that CO2 injection ahead of hydrogen yielded the highest storage capacity with , then CH4: and finally, N2: . At lower injection rates (0.2–0.6 cc/min), CH4 cushion gas exhibited the highest recovery (42%), whereas at higher injection rates (1.2–10 cc/min), CO2 resulted in the highest, with 33%. These findings emphasize cushion gas's role in enhancing hydrogen storage capacity and production efficiency in depleted gas reservoirs.
期刊介绍:
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
