Geological storage of CO 2 is a promising technique to mitigate anthropogenic CO 2
emissions. The effectiveness of CO 2 storage in the subsurface formations relies on various …

This study provides a critical review of Underground Hydrogen Storage (UHS), emphasizing
its potential as a viable energy storage option despite several associated challenges. These …

Implementation of the hydrogen economy for emission reduction will require storage
facilities, and underground hydrogen storage (UHS) in porous media offers a readily …

Depleted oil and gas reservoirs have been recognized as prevailing alternatives to store
hydrogen (H2). However, only a few attempts have been perused to evaluate hydrogen …

Continuous CO 2 injection (CCI) into saline aquifers suffers from low sweep efficiency. While
utilizing foam can effectively address this issue, a relatively potent foam design may …

The hysteresis effect is a key factor to accurately predict the fluid distribution and production
performance of fracturing-shut in-flowback-production (FSFP) process in tight oil reservoirs …

For modelling studies of underground storage of carbon dioxide and hydrogen, it is
important to have a consistent set of relative permeability and capillary pressure–saturation …

We perform single-phase and two-phase flooding on Edwards Brown rock samples. The
single-phase injection was of seawater or CaCl2 brine, at successive salinities 0.63, 0.21 …

Underground hydrogen storage (UHS) is crucial in facilitating the transition to clean energy
by reducing reliance on fossil fuels and ensuring a stable supply of emission-free energy …

Few laboratory studies compared tertiary gas injection using N 2, CH 4, and CO 2. However,
these studies only focussed on oil recovery without examining CO 2 storage. This study …
