The recent trends towards carbon net zero and the development of renewable
energy as an alternative source to fossil fuels has resulted in a major environmental focus being placed on decarbonisation projects with a big emphasis on the potential for carbon capture, utilisation and storage (CCUS).
For both carbon utilisation and storage waste carbon dioxide (CO2) from heavy
industry is captured and transported to site for injection into geological reservoirs which will prevent the release of large quantities of CO2 into the atmosphere. In addition, the captured CO2 can also be used for a variety of industrial purposes such as the production of synthetic fuels or in the food and beverage industry.
Several processes for carbon capture exist such as adsorption, absorption,
membrane gas separation, gas hydrate formation and mineralisation and these
technologies will be reviewed to identify the best potential methods for use with
carbon utilisation and storage.
Although CO2 has been injected into geological formations for several decades for various purposes, including enhanced oil recovery, the long-term storage of CO2 is a relatively new concept. Geological formations are currently considered the most promising for CO2 storage, but a general problem is that long term predictions about submarine or underground storage security are very difficult and uncertain, and there is still the risk for some CO2 to leak into the atmosphere. However, good monitoring techniques and production chemistry and technology, which can be transferred across from the oil and gas industry, should be able to help improve long term storage efficiency.
The focus of this paper will be on CO2 capture and storage methods. Carbon capture technologies will be reviewed and the impact of CO2 injection into saline aquifers and basalts with the potential to mineralise the injected CO2 in the reservoir will be discussed. In addition, the use of production chemicals like corrosion and scale inhibitors, surfactants, CO2 scavengers and polymers will highlight how production chemicals could improve carbon capture and storage methods.
