Carbon Capture, Utilization and Storage
Introduction The need to limit the harmful effects of climate change is a powerful motive for preventing carbon dioxide emissions from entering the atmosphere, and for removing CO2 that is already there, but there can be subsidiary aims associated with carbon capture, and there are many methods of accomplishing it. According to a definition published in 2014, “Carbon Capture, Utilization, and Storage (CCUS) encompasses methods and technologies to remove CO2 from … flue gas and from the atmosphere, followed by recycling the CO2 for utilization and determining safe and permanent storage options” (RCN-CCUS, 2014a). A definition of carbon capture and storage (CCS) used by Torvanger (2020) “refers to a group of technologies that reduce emissions of carbon dioxide from coal-fired or gas-fired power stations, or from process industries." The term sequestration is also used for the removal of CO2 from the atmosphere or from combustion gases, and permanent prevention of its ret
