<span>This seminar discusses both indirect and direct-fired supercritical CO2 (sCO2) power cycles, briefly reviews the status of pilot plants under development for each of these cycles, and discusses NETL&rsquo;s systems studies of coal-fueled commercial-scale sCO2 plants with carbon capture and storage (CCS).&nbsp; Indirect sCO2 systems studied include an oxy-fired circulating fluidized bed heat source coupled to various sCO2 power cycles. &nbsp;The direct-fired sCO2 cycle design is thermally integrated with a Shell gasifier to efficiently burn syngas within the oxy-combustor of the sCO2 cycle. &nbsp;The performance and cost analyses of these plants are discussed, as well as comparisons to alternative cycles with CCS.&nbsp; Results show that coal-fueled sCO2 plants of either type can exceed 40% HHV plant efficiency with CCS, and have a reduced cost of electricity relative to other cycles.&nbsp; Other cycle configurations that offer further improvements in plant performance and cost-effectiveness are also discussed.</span>
