A framework for pore-level imaging to directly compare the behavior of hydrogen and carbon dioxide when stored in reservoir rocks, with the goal of improving the safety and efficiency of underground clean energy storage.
Ahmed Khaled Al Zaabi’s innovation is the first framework of its kind for pore imaging, directly comparing the behavior of hydrogen and carbon dioxide within carbonate reservoir rocks to enable safe and efficient underground storage of clean energy. The idea stemmed from the limited understanding of the behavior of these two gases within reservoir rocks, which has restricted the safe and scalable use of underground hydrogen and carbon dioxide storage to reduce emissions.His framework combines advanced high-resolution computed tomography with reservoir state experiments and pore modeling to visualize and quantify the movement, diffusion, and retention of both gases under identical subsurface pressures and temperatures.By studying both gases under identical conditions, the system isolates key differences in their flow behavior, revealing that hydrogen exhibits faster diffusion and unique communication patterns, while carbon dioxide displays stronger capillary forces.These high-resolution observations are translated into engineering metrics—such as relative permeability and occupancy maps—that operators can directly apply to reservoir inspection, injection planning, and long-term containment assessment, supporting energy transition goals like the UAE’s Net Zero 2050 strategy.This framework is the first to generate comparative pore-level datasets for hydrogen and carbon dioxide in carbonate rocks, bridging the gap between fundamental subsurface physics and real-world industry applications to design safer and more efficient storage strategies.Future plans include expanding the framework to a wider range of reservoirs, integrating the results into full-scale field reservoir simulators, and collaborating on field pilot studies.
