Carbon Capture Storage is a process designed to mitigate carbon dioxide emissions from large point sources. The CO2 is captured before it is released into the atmosphere and stored underground in depleted oil and gas reservoirs, saline formations or deep coal seams, salt domes or basaltic rock.
Earthline can help define high-grade structures that may be suitable carbon capture storage sites by delineating salt bodies and basaltic rocks and associated faulting and fracturing.
Globally, carbon mineralisation in these rock types has the potential of sequestering up to 60,000,000 Gt CO2 if the resource is economically accessible and ultimately fully carbonated.
CO2 can be stored in depleted oil and gas reservoirs or saline aquifers. Storing CO2 in basaltic rock has advantages over these conventional storage sites, which lack the minerals (such as calcium, magnesium and iron) required to form carbonate minerals, which fix CO2 into a solid form. Basaltic rocks are composed of up to 25% calcium, magnesium, and iron.
They are also common and cover up to 10% of the Earth’s surface as well as significant areas of the ocean floor.
CCS is a crucial process for reducing greenhouse gas emissions and combating climate change worldwide, particularly in industries such as power generation and cement production, where it isn’t easy to eliminate emissions. However, finding suitable storage sites can be challenging, which is where Earthline Consulting can help, as geophysical surveying techniques are becoming more important in the detection of storage sites for carbon capture.
CCS continues to be researched and developed as part of the broader portfolio of strategies to mitigate climate change.
