Partnership for CO2 Capture (PCO2C) Technology Development
Development of economically feasible carbon capture technology presents one of the biggest challenges to the fossil energy industry in the 21st century. Many existing technologies are capable of capturing carbon from coal-fired power plants, but most are expensive and inefficient. Development and evaluation of new technologies are critical steps toward economical carbon capture. To address this challenge, the EERC initiated a program to evaluate several CO2
capture technologies that are among the most advanced systems under development. PCO2
C was developed with the overall goal of advancing the state of CO2
capture by evaluating and demonstrating those technologies with the most commercial viability for utility applications. In performing pilot-scale testing of these systems, PCO2
C identifies the strengths and weaknesses of each technology to allow for enhanced performance and decreased costs for future applications.
C project is being conducted in three phases. During Phase I of PCO2
C, the focus was on understanding and developing two platform-based technologies: solvent-based absorption and stripping (postcombustion capture) and oxygen-fired combustion. Phase I results indicate that technological advances are the main way to reduce the costs of capturing CO2
using a retrofit oxy-fired technology. For postcombustion capture, 90% CO2
capture can be met with monoethanolamine (MEA) and advanced solvents. However, the EERC has shown that use of advanced solvents can be expected to reduce the cost of CO2
Phase II of PCO2
C focused on further developing the most promising technologies studied in Phase I. Phase II utilized the information gathered during Phase I for the development of lower-cost and more effective capture technologies as well as their integration into a total system that provides substantial economic and environmental benefits.
Currently, Phase III is continuing the work of Phase II by providing a platform for technologies to be tested so that the gathered data can be evaluated with a direct comparison to MEA and to investigate flue gas precleaning technologies to remove contaminants that can reduce solvent life. This phase continues international involvement and cooperation, which shows the EERC’s commitment to advancing capture technologies for a world with high power demands but doing so with a responsibility to environmental stewardship.
