The flexible CLC-CFB reactor concept is the core of the Bio-FlexCLC project. This is a transformative technology with respect to CO2 capture. It has significant advantages in comparison to current state-of-the-art capture technologies:
- Strong compatibility with existing infrastructure, as the technology is based on fluidized bed combustion, a common technology for heat and power production.
- A flexible system that can be used as CLC with CO2 capture, but can readily switched to CFB-mode without CO2 capture, but still with net-zero emissions.
- Low efficiency penalty for CO2 capture, as the CO2 is obtained in pure form inherently in the process.
- Low investment cost, as the plants will be of similar size and layout as conventional fluidized bed boilers.
- Consequently, low cost for CO2 capture (target: 50% reduction compared to amines for key applications).
- High rate of CO2 capture, approaching 100% for direct use of solid biogenic residues and wastes
- Reduced emissions of e.g., NOx and CO (target: 100%) by conditioning of the small fuel reactor flow.
- Reduced corrosion, as aggressive ash will be reduced (target: >90%) in connection to heat-transfer surfaces.
- High feedstock flexibility, especially when considering thermochemical treatment of difficult fuel fractions.
