Oxy combustion turbine power plants

The leading technologies for capture of CO2 at gas fired power plants have usually been considered to be post combustion and pre combustion capture but there is increasing interest in the alternative of gas-fired oxy-combustion turbine cycles. In these cycles fuel gas is combusted at high pressure using high purity oxygen, moderated by recycled CO2 and/or H2O, and the resulting hot high pressure gas is expanded in a turbine to generate electricity.

This webinar will summarise a techno-economic study on oxy-combustion turbine power plants with CCS that was published recently by IEAGHG. It will describe four leading cycles, namely the Supercritical Oxy-Combustion Combined Cycle (SCOC-CC), the Modified S-Graz cycle and cycles being developed by NET Power and Clean Energy Systems (CES). The thermal efficiencies, capital costs, costs of electricity generation and costs of CO2 avoidance of natural gas fired plants will be presented. Results for a coal fired oxy-combustion turbine plant will also be presented. (Please note title slide is missing from this recording)
