An Overview of Clean Coal Technologies II: Mitigating the Environmental Impacts by Continuous Improvement in Coal Combustion and CCS Technology

Abstract

This article is the second of two articles aboutcurrent and prospective clean coal technologies. The first article discussed the source and formation mechanism of the major pollutants in coal-fired power generation together with pre-combustion and post-combustion pollutant control strategies. This article provides an overview of the existing and developing coal-fired electricity production options. The influence of the efficiency improvements on the CO₂ mitigation and different applications of CO₂ capture and storage technologies are also examined from both current and future perspectives.

Keywords:

• CO₂ capture and storage
• coal combustion technologies
• coal-fired power plants
• efficiency
