Deep Saline Formations
Deep saline formations are very large, porous rock formations that are typically several kilometres below the surface and contain water that is unusable because of its high salt and/or mineral content. This saltwater brine is around 10 times saltier than the oceans and has been trapped by impermeable rock, called a “cap rock,” for millions of years. Through advanced geological techniques such as 3D and 4D seismic testing, we are able to identify these reservoirs and select geological formations with solid cap rock formations.
The Intergovernmental Panel on Climate Change Special Report on Carbon Dioxide Capture and Storage reported that the global capacity of deep saline storage sites was many hundreds of times greater than the annual CO2 emissions from industrial sources, and concluded that there is enough storage capacity to store emissions for the next 200 years.
