Advanced Carbon Dioxide Capture Technology for Low Rank Coal Integrated Gasification Combined Cycle (IGCC) Systems

Performer: TDA Research Inc.

Project No: FE0007966

Project Description

TDA Research, Inc. (TDA) is demonstrating the technical and economic viability of a new Integrated Gasification Combined Cycle (IGCC) power plant designed to efficiently process low-rank coals. The plant uses an integrated carbon dioxide (CO2) scrubber/water gas shift (WGS) catalyst to capture more than 90 percent of the CO2 emissions, while increasing the cost of electricity by less than 10 percent compared to a plant with no carbon capture.
TDA is optimizing the sorbent/catalyst and process design, and assessing the efficacy of the integrated WGS catalyst/CO2 capture system, first in bench-scale experiments and then in a slipstream field demonstration using actual coal-derived synthesis gas. The results will feed into a techno-economic analysis to estimate the impact of the WGS catalyst/CO2 capture system on the thermal efficiency of the plant and the cost of electricity.
