... illnesses; glaciers melting; and freshwater aquifers becoming more vulnerable to saline water intrusion. United Nations researchers predict a 20% decline in renewable water resources for every 1°C rise in the world average temperature. For most of us, this is daily news and we have heard it for many years...

...) As shown in Fig. 1, CCUS involves capturing CO 2 from a fossil-fuel-fired power plant or industrial facility and processing it to a practically pure form, transporting it to a nearby geologic storage site using pipelines, and injecting it into saline aquifers for long-term sequestration or depleted oil/gas...

... component, and some think depleted oil and gas fields—with an emphasis on the latter—may fit the bill. Saline aquifers are being eyed for the role too. But as this all suggests, no one has ever attempted to use these formations for hydrogen storage. Just four shallow salt formations, three salt domes...

To demonstrate the effect on seismic amplitude of GWC movement, brine substitution was performed in selected reservoir...

.... Their thickness ranges from 100 to 150 m, with a porosity of 15–32% and permeability of 10–1600 md. These fields are believed to be supported by a regional aquifer several thousand feet thick. Large seafloor subsidence has been observed in these reservoirs. Storage-Capacity Estimation Storage capacity...

It is known that these spaces appear big enough to accommodate billions of tons of carbon; beyond that, the information is skimpy...
