A Multi-Pollutant Framework for Evaluating CO2 Control Options for Fossil Fuel Power Plants

As part of DOE/NETL’s Carbon Sequestration Program, we are developing an integrated, multi-pollutant modeling framework to evaluate the costs and performance of alternative carbon capture and sequestration technologies for fossil-fueled power plants. The model calculates emissions, costs, and efficiency on a systematic basis at the level of an individual plant or facility. Both new and existing facilities can be modeled, including coal-based or natural gas-based combustion or gasification systems using air or oxygen. CO2 storage options include various types of geologic formations, as well as ocean and terrestrial sinks. A key feature of the integrated modeling framework is the explicit characterization of uncertainties in model inputs and results using a probabilistic (stochastic simulation) capability. This capability provides quantitative estimates of the technological and economic risks associated with alternative CO 2 capture and sequestration technologies. This paper reviews the goals and scope of this project and presents preliminary results for the case of carbon capture from coal combustion.
