Hydrogen (H 2) is currently considered a clean fuel to decrease anthropogenic greenhouse
gas emissions and will play a vital role in climate change mitigation. Nevertheless, one of …

The oxidation of fossil fuels produces billions of tons of anthropogenic carbon dioxide (CO 2)
emissions from stationary and nonstationary sources per annum, contributing to global …

Expectations for energy storage are high but large-scale underground hydrogen storage in
porous media (UHSP) remains largely untested. This article identifies and discusses the …

Hypothesis The mitigation of anthropogenic greenhouse gas emissions and increasing
global energy demand are two driving forces toward the hydrogen economy. The large …

Subsurface porous formations provide large capacities for underground hydrogen storage
(UHS). Successful utilization of these porous reservoirs for UHS depends on accurate …

While carbon capture and sequestration (CCS) has garnered many headlines in the recent
past, its wider applicability on an industrial scale is yet to be explored due to a plethora of …

In H 2, CO 2 and natural gas geo-storage, rock-fluid interfacial tension (γ rock− fluid) is a key
parameter which influences pore-scale fluid distribution and reservoir-scale gas storage …

Hydrogen energy has tremendous potential as a clean fuel in this energy transition. To build
up the full-scale hydrogen energy supply chain, large-scale hydrogen storage is of vital …

Changing oil-wet surfaces toward higher water wettability is of key importance in subsurface
engineering applications. This includes petroleum recovery from fractured limestone …

We review the literature data published on the topic of CO2 wettability of storage and seal
rocks. We first introduce the concept of wettability and explain why it is important in the …
