Abstract
Abstract Studies conducted at the Energy Research Centre at the University of Ulster, Coleraine have been made using an ECLIPSE process simulator to perform technical and economic analysis of a number of coal-fired power generation technologies, including an analysis of the effect of a carbon tax on the relative economics of these processes. They have also examined the impact on these technologies of installing equipment for sequestering CO 2 and using the CO 2 produced in enhanced oil recovery. The results show that advanced coal-fired power generation systems provide a means of reducing CO 2 emissions through improved conversion efficiency without adversely affecting electricity selling prices. A carbon tax of £32/tonne CO 2 would increase the breakeven electricity selling price by about 65%–75%, but even at this high level a carbon tax does not provide any real incentive to develop these advanced coal-fired power generation systems. Selling liquid CO 2 for use in enhanced oil recovery is potentially attractive for all coal-fired power generation technologies.
