Project Description

Research Triangle Institute (RTI) will develop novel third-generation fluidizable solid sorbents for their sorbent-based carbon dioxide (CO2) capture process. Two novel sorbent approaches, based on hybrid-metal organic frameworks (MOFs) and hybrid-phosphorus (P)-dendrimers, have been identified with promise to achieve DOE’s performance and cost goals. The primary project goal is to design and synthesize several novel hybrid-based MOF and P-dendrimers with enhanced stability and higher CO2 capacity, then thoroughly evaluate and show their potential to further drive down the cost of CO2 capture. From this group, the most cost-effective sorbent that can meet DOE’s goals will be selected. RTI researchers will conduct lab-scale testing in RTI's packed-bed reactor and fluidized, moving-bed reactor with simulated flue gas; evaluate the sorbents’ stability and the impact of contaminants, temperature, and humidity; and complete high-level technical and economic analyses to understand the potential of these sorbents to substantially reduce the cost associated with CO2 capture from coal-fired power plants. The project is designed to explore the promise of novel solid CO2 sorbents to further lower the cost of CO2 capture, establish an understanding of how process elements influence CO2 capture performance, and provide information for a technology feasibility study, which will prove the commercial potential of a hybrid solid sorbent-based CO2 capture technology.

Project Benefits

The advanced hybrid-solid sorbents for fluidized-bed CO2 capture are anticipated to further lower the cost of CO2 capture. Successful results will show their potential to meet or exceed DOE’s CO2 capture process performance targets of a greater than 90 percent CO2 capture rate with 95 percent CO2 purity and less than a 30 percent increase in the cost of electricity, and achieve sufficient technology readiness for the next-stage of development.
