Carbon dioxide capture technology for the coal-powered electricity industry : a systematic prioritization of research needs

摘要

Coal is widely relied upon as a fuel for electric power generation, and pressure is increasing to limit emissions of the CO2 produced during its combustion because of concerns over climate change. In order to continue the use of coal without emitting CO2, low cost technologies must be developed for capturing CO2 from power plants. Current CO2 capture technology is expensive, both in terms of capital and operating cost, so research and development efforts will be heavily relied upon to improve the economic profile of the technologies. With scarce resources available for R&D, and a number or different technologies competing for these funds, efforts must be prudently prioritized in order for successful advancements to be realized. This thesis assesses the state-of-the-art CO2 capture technologies available today, as well as the leading technology options for improvement. It also examines types of R&D, government and industry roles in R&D efforts, and methods and tools for managing these efforts. From these analyses, qualitative conclusions about how to prioritize CO2 capture technology R&D efforts to ensure advancement are offered.
