Journal ArticleDOI
Recent advances in carbon capture storage and utilisation technologies: a review
Ahmed I. Osman,Mahmoud Hefny,Mahmoud Hefny,M. I. A. Abdel Maksoud,Ahmed M. Elgarahy,David Rooney +5 more
TL;DR: In this paper, three major technologies that are utilised for carbon capture are evaluated: pre-combustion, post combustion and oxyfuel combustion, and they compare carbon uptake technologies with techniques of carbon dioxide separation.
Journal ArticleDOI
Hydrogen production, storage, utilisation and environmental impacts: a review
Ahmed I. Osman,Neha Mehta,Ahmed M. Elgarahy,Mahmoud Hefny,Mahmoud Hefny,Amer Al-Hinai,Ala’a H. Al-Muhtaseb,David Rooney +7 more
TL;DR: In this paper, the authors compared the environmental impact of hydrogen production routes by life cycle analysis and showed that combining electrolysis-generated hydrogen with hydrogen storage in underground porous media such as geological reservoirs and salt caverns is well suited for shifting excess off-peak energy to meet dispatchable on-peak demand.
Journal ArticleDOI
Image-based modeling of spontaneous imbibition in porous media by a dynamic pore network model
TL;DR: In this paper, a dynamic pore-network model for imaged-based modeling of spontaneous imbibition in porous media is proposed. But the model is not suitable for the case of sintered glass beads.
Journal ArticleDOI
Synchrotron-based pore-network modeling of two-phase flow in Nubian Sandstone and implications for capillary trapping of carbon dioxide
Mahmoud Hefny,Mahmoud Hefny,Chaozhong Qin,Martin O. Saar,Martin O. Saar,Anozie Ebigbo,Anozie Ebigbo +6 more
TL;DR: In this paper, a quasi-static pore-network model was used to simulate the equilibrium positions of fluid-fluid interfaces, and thus determine the capillary pressure and relative permeability curves.
Journal ArticleDOI
Sequence stratigraphy and depositional environments of Late Cretaceous–Early Palaeogene succession, North Eastern Desert, Egypt
TL;DR: In this article, foraminiferal contents and geochemistry of 199 samples collected from three surface sections in the southern Galala Sub-basin, North Eastern Desert of Egypt, have been studied in detail.
