One of the most relevant limitations for CO2 capture or utilization of massive deployment is the high energy consumption of these processes. Energy penalties may vary from 7.5% to 10.5% points depending on the selected carbon capture process. When facing the utilization of carbon, this penalty ranges widely depending on the final conversion process. It is clear that the reduction of these penalties is a key point to make these technologies economically feasible. Thus, energy and mass integration with other systems, which allow the better use of energy limiting losses, must be investigated. This chapter puts together the present scenario of the capture systems and the potential future opportunities to integrate them with suitable conversion processes to enhance the efficiency of the hybrid systems. Two potential synergies between carbon utilization and conversion processes are presented to analyze the increase of energy efficiency after proper integration.
