Carbon capture and storage technologies are essential for industries looking to mitigate their carbon footprints. These systems capture carbon dioxide emissions from sources like power plants and industrial processes, preventing them from entering the atmosphere. By investing in CCS, companies can continue to utilize fossil fuels while significantly reducing their environmental impact.

4.1 Capturing Carbon Emissions

Carbon capture involves the extraction of CO2 from exhaust gases produced by industrial processes or power generation. This is typically achieved using chemical solvents that absorb CO2 from the flue gases. The captured CO2 is then compressed and transported to storage sites, where it is injected into deep geological formations for long-term sequestration.

For example, Shell’s Quest CCS project in Canada captures and stores over one million tonnes of CO2 annually from oil sands operations. This initiative not only reduces emissions but also demonstrates the viability of large-scale CCS projects.

4.2 Storage Solutions

The storage aspect of CCS involves securely sequestering the captured CO2 in geological formations such as depleted oil and gas fields, deep saline aquifers, or unmineable coal seams. These formations are selected based on their ability to contain CO2 securely and permanently.

Norway’s Sleipner project is a pioneering example of CO2 storage. Operating since 1996, it injects about one million tonnes of CO2 per year into a deep saline aquifer beneath the North Sea. The project has provided valuable data on the long-term behavior of stored CO2, contributing to the development of best practices for CCS.

4.3 Enhanced Oil Recovery (EOR)

An additional benefit of CCS is its use in enhanced oil recovery (EOR). Injecting CO2 into mature oil fields can increase oil extraction rates by reducing the viscosity of the oil. This dual benefit of reducing emissions and enhancing oil recovery makes CCS an attractive option for industries.

For instance, Occidental Petroleum in the United States utilizes CO2 captured from industrial sources for EOR, effectively combining emission reduction with increased oil production. This approach not only mitigates the environmental impact but also provides economic benefits.
