A Statistical Analysis of Fluid Interface Fluctuations: Exploring the Role of Viscosity Ratio

Entropy
Understanding multiphase flow through porous media is integral to geologic carbon storage or hydrogen storage. The current modelling framework assumes each fluid present in the subsurface flows in its own continuously connected pathway.

Geological hydrogen storage

The underground geological storage of gases, including natural gas, hydrogen, and CO2, is a key enabler for a reliable and cost-effective low-carbon economy. Furthermore, large-scale underground gas storage capacities for natural gas and hydrogen (blue or green) are essential to compensate for possible disruptions and seasonal supply and demand ...
