![]() ![]() The pipelines are pressurized as the only option for transporting the CO2 over long distances. ( September 2023)Ĭarbon capture and utilization (CCU) is defined as capturing C02 from industrial processes and transporting it via pipelines to where one intends to use it in industrial processes. The profitability of CCU depends partly on the carbon price of CO 2 being released into the atmosphere.Ĭarbon capture and utilization may offer a response to the global challenge of significantly reducing greenhouse gas emissions from major stationary (industrial) emitters. The availability of other raw materials to create a product should also be considered before investing in CCU.Ĭonsidering the different potential options for capture and utilization, research suggests that those involving chemicals, fuels and microalgae have limited potential for CO 2 removal, while those that involve construction materials and agricultural use can be more effective. 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. ![]() 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. Comparison between sequestration and utilization of captured carbon dioxideĬarbon capture and utilization ( CCU) is the process of capturing carbon dioxide ( C O 2) from industrial processes and transporting it via pipelines to where one intends to use it in industrial processes. ![]()
