Advanced Combustion

Demonstration of a Novel Supercritical Carbon Dioxide Power Cycle Utilizing Pressurized Oxy-Combustion in Conjunction with Cryogenic Compression
Southwest Research Institute
Project Number: DE-FE0009395

Southwest Research Institute (SwRI) is developing a novel supercritical carbon dioxide (sCO2) advanced power system utilizing pressurized oxy-combustion in conjunction with cryogenic compression. The proposed power system offers a leap in overall system efficiency while producing an output stream of sequestration ready CO2 at pipeline pressures. The system leverages developments in pressurized oxy-combustion technology and recent developments in sCO2 power cycles to achieve high net cycle efficiencies and produce CO2 at pipeline pressures without requiring additional compression of the flue gas.

The project objective is to demonstrate the advantages of the oxy-combustion system using a thorough engineering design analysis to refine the proposed cycle, demonstrate cycle efficiencies, and identify critical components that have a significant impact on cycle performance. The engineering design analysis will be performed in conjunction with an economic analysis to quantify the cost advantages of the proposed cycle. For critical cycle components a technology assessment will be performed to identify current TRL levels and development paths required to mature essential technologies into a commercially viable system.
