Carbon Capture and Storage

Duke Energy is collaborating in a number of carbon capture and storage research projects to explore potential technologies to capture CO₂ from the flue gas of coal-fired power plants.

• We are hosting a project at our East Bend Power Plant in Kentucky to demonstrate an algae-based system for CO₂ mitigation from coal-fired power plants. Project participants include the University of Kentucky Center for Applied Energy Research and the University of Kentucky Department of Biosystems and Agriculture Engineering.  While the primary focus of the project is to demonstrate how to use algae to reduce CO₂ emissions produced by coal-fired power plants, the project also focuses upon studying the production of biofuels and other bioproducts from the algae to demonstrate the economic feasibility of using algae to capture CO₂.

• Duke Energy is hosting a CO₂ geologic sequestration field demonstration project at its East Bend Power Plant in Kentucky in conjunction with the Midwest Regional Carbon Sequestration Partnership.  The project is part of a national effort sponsored by the U.S. Department of Energy's National Environmental Technology Laboratory to develop strategies for reducing carbon dioxide emissions.
• We are an active member of the U.S. China Clean Energy Research Center's Advanced Coal Technology Consortium (CERC-ACTC). The Advanced Coal Technology consortium addresses technology and practices for advanced coal use, as well as carbon capture, utilization and storage. Specific research areas Duke Energy is involved in as a member of the CERC-ACTC include:
  • Integrated gasification combined cycle with carbon capture and storage
  • Large-scale post-combustion  CO₂ capture, utilization and storage
  • Bio-fixation of CO₂ with algae
• We are partnering with a Chinese company to perform a post combustion capture study at our Gibson Station in Indiana.  The first phase of the project will develop an engineering and pre-feasibility study for annually capturing approximately 1 million tons, or 25 percent of CO₂ from the exhaust gas of Gibson Unit 3.  Additionally, this pre-feasibility study will propose several options for using the captured CO₂.
