![]() ![]() As CO 2 is a thermodynamically stable form of carbon, manufacturing products from it is energy intensive. There are several additional considerations to be taken into account. ![]() If, in addition, this product substitutes one of fossil origin an overall CO 2 emission reduction occurs. Regarding a single product, CCU does not result in a net carbon positive to the atmosphere. Other commercial products include plastics, concrete and reactants for various chemical synthesis. Instead, CCU aims to convert the captured carbon dioxide into more valuable substances or products such as plastics, concrete or efuel while retaining the carbon neutrality of the production processes.ĬCU and CCS are sometimes discussed collectively as carbon capture, utilization, and sequestration (CCUS).Ĭaptured CO 2 can be converted to several products: one group being alcohols, such as methanol, to use as efuels and other alternative and renewable sources of energy. ![]() ĬCU differs from carbon capture and storage (CCS) in that CCU does not aim nor result in permanent geological storage of carbon dioxide. Carbon capture and utilization may offer a response to the global challenge of significantly reducing greenhouse gas emissions from major stationary (industrial) emitters. Comparison between sequestration and utilization of captured carbon dioxideĬarbon capture and utilization ( CCU) is the process of capturing carbon dioxide ( C O 2) to be recycled for further usage. ![]()
