| 제목 | CO2 Capture Technology:A Review of Fundamentals and Development Status |
| 초록 | Capturing CO2 from fossil fuel-based power plants is one of the significant ways the world could reduce anthropogenic emissions of greenhouse gases.In 2009 the author participated on a team assembled by the Global CCS Institute to evaluate the status of carbon capture and storage (CCS) research and development and to identify gaps in the worldwide R&D effort.A conclusion from that study is that while technologies exist today to capture CO2 from power plants, those technologies have either not been demonstrated at large scale or add significant cost and performance penalties or both.A number of “next generation” CO2 capture technologies are under development which could lower the cost impact of CCS, but it may be difficult to have those technologies demonstrated at commercial scale by 2020 due to the long timelines for developing emission control processes, and one needs to treat their current estimates for cost savings with a level of healthy skepticism due to the long development path they still most travel. This presentation will describe the three generic processes for capturing CO2 from fossil fuel-based power plants (pre-, post- and oxy-combustion capture) and will review the technical challenges as well as the development status of each of the three approaches.The concept of Technical Readiness Levels (TRLs) will be introduced as a method for judging and tracking the development status of technologies, and the TRLs of various CO2 capture technologies will be identified. The relationship of TRL to cost estimate accuracy will also be discussed.Development of other emission control technologies for power plants has shown that cost estimates for technologies at the initial stages of development are often overly optimistic and those estimates grow until they peak at the time of the first large demonstration.The costs then decline as traditional learning curves come into play. Estimates published by the US Department of Energy, the International Energy Agency and the Global CCS Institute of the cost of capturing CO2 will be reviewed, and the timeline for developing and demonstrating new CO2 capture technologies will be discussed and compared to the often stated goal of having CCS technology commercially demonstrated by 2020. |
