Abstract

Carbon dioxide (CO2) emission from thermal power plants is one of the primary causes of global warming. Demand has therefore been increasing for innovative technologies to reduce CO2 emission. To meet this demand, Toshiba has been engaged in the development of a CO2 turbine and combustor applying a supercritical CO2 cycle fossil power system that separates and collects CO2 without the need for any carbon capture system. The combustor of the new system burns a mixture of fossil fuel and oxygen combined with CO2 to produce a working fluid, mainly consisting of high-temperature and high-pressure CO2 and water vapor, which is used to drive the CO2 turbine generator.
