The partners are expected to demonstrate a new supercritical carbon dioxide power cycle using pressurized oxy-combustion – a process that uses pure oxygen instead of air as the primary oxidant.
SwRI program director of mechanical engineering division said that objective of the process to achieve 90% CO2 removal at no more than a 35% increase in the cost of electricity besides achieving 90% CO2 capture.
"The proposed power cycle offers a step up in overall system efficiency while producing an output stream of sequestration-ready CO2 at pipeline pressures. "
"The power cycle leverages developments in pressurized oxy-combustion technology, an SwRI-developed cryogenic CO2compression scheme and recent developments in supercritical CO2 power cycles," Brun added.
