- Carbon Capture and Storage (CCS) and Carbon Capture and Utilization (CCU) are two CO2-based technologies aiming at mitigating climate change by capturing and either permanently storing CO2 (CCS) or using it as a feedstock (CCU) for commercial products, e.g., chemicals, fuels, or plastic products. Whereas the implementation of CCS has attracted considerable public opposition in Europe and the US, the CCU-technology is still in an early development stage. This research takes a social science perspective and investigates the awareness, general perception and acceptance of CCS in comparison to CCU by applying an online survey in Germany (2017, n = 509). In addition, the risk perception of single steps in the CCU/CCS process chains was explored (CCS: CO2-capturing, CO2-transport, CO2-storage; CCU: CO2-capturing, CO2-transport, temporary CO2-storage, production, product usage, product disposal). Significant differences were found for the perception and acceptance of CCS and CCU: while both technologies were generally accepted, CCU was perceived significantly more positively than CCS. CCS-acceptance was negatively influenced by storage and transport risks; for CCU, disposal and product risks decreased acceptance. Our results contribute to the development of communication concepts for a successful implementation of CO2-based technologies by considering public concerns.
