What are suitable overall concepts for industrial carbon management and which capture technologies are suitable for this?
Carbon management is the handling of CO2-emissions that are unavoidable or difficult to avoid. This is relevant, for example, for the cement or lime industry with their raw material-related process emissions from lime burning, as well as thermal waste treatment plants. Carbon management can also play a role for energy suppliers with biomass power plants and companies in the petrochemical, glass or paper production industries. Techno-economic knowledge and model- and scenario-based analyses of the industries, their transformation paths and embedding in the overall system therefore represent an important building block for sensibly dimensioning and economically operating the necessary infrastructure.
The basic options for CO2 capture – pre-combustion, oxyfuel combustion and post-combustion – are in turn subdivided into various capture technologies. Framework conditions such as technical availability (TRL), space requirements, CO2 concentration in the exhaust gas stream and selected techno-economic key figures are decisive for selecting the right separation technology for the respective processes. In addition to current technological developments and scientific findings, practical experience must also be taken into account.
