TDA Research, Inc. is designing, constructing, and operating a slipstream 0.5-megawatt-electric (MWe) pilot-scale process for post-combustion carbon dioxide (CO2) capture using their low-cost alkalized alumina sorbent to conduct parametric and long-term steady-state testing to demonstrate the effectiveness of the technology to reduce the cost of CO2 capture and to develop scale-up conditions for the process.
