New Research Publication: Risk of H2 Leakage into Caprock and the Role of Cushion Gas as a Barrier in H2 Geo-Storage: A Molecular Simulation Study
A critical challenge in the field implementation of Underground Hydrogen Storage (UHS) is ensuring the long-term integrity of caprock, particularly its ability to maintain an effective seal. The risk of hydrogen penetrating the caprock could compromise its sealing capacity, making it essential to understand and mitigate potential leakage pathways for safe and reliable storage.
Our recent collaborative research explores the interactions and behaviour of fluid species (H₂ and cushion gas) within nano- and meso-scale pores in the caprock, and quantifies the partitioning of each gas from the bulk reservoir into single pore clay minerals using Molecular Simulations.
