Carbon Sequestration Systems Using Direct FuelCell for Combined Carbon Dioxide Separation and Power Generation

摘要

FuelCell Energy (FCE) has developed novel system concepts for separation of carbon dioxide from greenhouse gas emission sources, using Direct FuelCell~? (DFC~?) technology. DFC is based on carbonate fuel cells featuring internal reforming. The unique chemistry of carbonate fuel cells offers an innovative approach for separation of CO_2 from fossil-fuel power plant exhaust streams (flue gasses). DFC-based CO_2 separation systems are suitable for many types of coal-based power plants, from existing pulverized coal (PC) plants to future integrated gasification combined cycle (IGCC) plants. The carbonate fuel cell system also produces electric power at high efficiency. Cost of electricity (COE) analysis of the DFC system suggests that the simultaneous generation of power and CO_2 capture is an attractive scenario for re-powering the existing coal-fueled power plants.
