Bio-FlexCLC
The Bio-FlexCLC consortium aims at developing and demonstrating a full-chain technology that utilizes biogenic residues and wastes for flexible CHP production with the possibility of cost-effective CO2 capture.
The concept is based on the chemical-looping technology and has the main features of i) low cost and energy for CO2 capture, as there is no gas separation equipment needed, ii) 100% CO2 capture possible while having low emissions of NOx, SOx and other harmful components, iii) low corrosion with improved steam data for improved electrical efficiency, iv) flexible system with respect to the heat/power ratio and v) flexibility to operate the system as a normal circulating fluidized bed without CO2 capture if conditions are not amiable for this. With such a flexible system we believe that end-users would be more willing to invest in CHP systems with BECCS even without current policy instruments in place.
The idea is to combine the break-through chemical-looping combustion (CLC) technology with conventional circulating fluidized bed (CFB) boilers, a technology widely used in Scandinavia and Europe for combined heat and power production. Bio-FlexCLC concept operating in CLC mode enables CHP production with negative emissions at low-cost while the concept is flexible to switch to CFB boiler mode to produce CHP with net-zero emissions.
Investing in CHP technologies utilizing biogenic and waste fuels, as developed in the Bio-FlexCLC project, offers a range of enduring advantages:
– A fuel combustion facility which can achieve negative emissions with CO2 capture.
– Facilitating the utilization of challenging-to-exploit or low-value bio resources like organic wastes.
– Creating new employment opportunities, particularly in biomass or residue-rich regions, such as rural areas.
– Reducing reliance on fossil fuels and mitigating the need for oil imports.
– Enhancing local and regional production autonomy and supply security.
– Most notably, contributing to the principles of the circular economy, particularly when resources like agricultural residues are effectively harnessed.
